From 57f2c1ffab2edeca862f3c9cc6947cf98b03c0a4 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 21 Aug 2026 17:46:02 +0000 Subject: [PATCH 01/61] KOKKOS: type-check the boundary tally computes before casting UpdateKokkos dispatched the boundary tally list with an unchecked C-style downcast to ComputeBoundaryKokkos, in tally_set() and again in the post-tally pass at the end of move(). compute react/boundary also sets boundary_tally_flag (compute_react_boundary.cpp:86) and so lands in blist_active (update.cpp:1939), but ComputeReactBoundary derives straight from Compute and has no Kokkos version, so pre_boundary_tally() wrote at offsets outside the object. tally_set() runs every timestep. The cast is equally wrong for a plain compute boundary under "-k on" without "-sf kk": sparta.cpp:389 installs the Kokkos core classes on "-k on" alone, while the compute stays the non-Kokkos class. Dispatch by dynamic_cast with an explicit error instead, matching what the surf tally list beside it already does (update_kokkos.cpp:1016,2554) and what CollideVSSKokkos does for the gas tally list (collide_vss_kokkos.cpp:602).

UpdateKokkos instead branched on the move template's DIM, and axisymmetric is dispatched as DIM == 1 (update_kokkos.cpp:216), so neither the DIM == 3 nor the DIM == 2 arm fired and "global field constant" was silently ignored for the whole run. field2d perturbs x[0..1] and v[0..1], which is exactly what the host applies: update.cpp:230 bans only field[1] for axisymmetric, and field[0] is explicitly allowed. Take that arm for DIM == 1 as well. No example covers this: global field appears only in examples/bfield, which is excluded from the KOKKOS regression run because fix field/grid and fix field/particle have no Kokkos version.

Without the break, the "react_modify compute_chem_rates yes" path -- which tallies and then keeps looking rather than returning -- incremented d_tally_reactions for all of them, reporting rates for reactions that never fired. The reaction list is per species pair, so this only shows up when a pair has two or more energetically possible reactions. examples/chem_rates runs N2/N only, where each pair has one, which is why the regression run stayed green.

The Kokkos endothermic-exchange branches instead sampled into react_prob and dropped the else clause, in both react_qk_kokkos.h and react_tce_qk_kokkos.h. A rejected draw therefore left a fractional value in react_prob, which then decided the reaction: in react_qk_kokkos.h react_prob is declared before the reaction loop, so the stale value also carried into later reactions for the same collision. The exothermic branches used a correct local prob but likewise dropped the else, so the rejection loop terminated on a stale probability. Sample into a local prob in all four places, matching the host. Neither style is exercised by any example, so nothing in the regression run reaches this code.

FixAmbipolar::surf_react() branches on j < 0, reads particles[j], and sets j = -1 to tell the caller to delete an electron it just created (fix_ambipolar.cpp:164). The Kokkos override left the third parameter unnamed and shadowed it with a local j holding the fix index, then passed that. The exchange branch could never be taken, particles[j] read an unrelated particle, and the delete signal never reached the caller. Name the parameter and use ifix for the fix index. Reachable only through a host surf_collide style, since the Kokkos styles handle the ambipolar and vibmode updates inside their own device paths.

Under Kokkos those three reported only the host-array formulas of the base classes, so on a GPU the device allocations -- most of the run's memory -- were invisible. Make the three virtual and override them, using the MemKK::memory_usage() view helper that already existed in memory_kokkos.h but had no callers. The base implementations are deliberately not called: the host arrays they measure are the host mirrors of the DualViews, so their formulas would double count what the overrides add. Their non-Kokkos terms are carried over instead -- next[] for Particle, the csurfs/csplits host pages for Grid, the per-surf int array for Surf. Each override counts the host span of every Kokkos view it owns, and adds the device span only when it is a distinct allocation; on a host-only backend the two views alias. Device-only structures with no host counterpart in either backend are counted unconditionally: the sort/reorder scratch for Particle, and the flattened Crs surf graphs, per-cell particle lists and halo index for Grid.

That is why examples/bfield was excluded from the KOKKOS regression run. Everything on the device side already existed: UpdateKokkos has the field_per_particle() and field_per_grid() kernels (update_kokkos.h:344,374), reads d_array_particle/d_array_grid off the KokkosBase (update_kokkos.cpp:383,580,589) and applies them in the move kernel (:1262-1273). Only the two fixes were missing, so update_kokkos is unchanged here. The grid- and particle-style variables these fixes evaluate are host-only (VariableKokkos inserts a host sync and defers to the base), so the evaluation stays on the host and only the result is published to the device. For field/grid that is nearly free: UpdateKokkos calls compute_field() once per fieldfreq steps, or once per run when fieldfreq is 0. field/particle runs every timestep (update.cpp:672) and so carries a per-step host round trip -- correctness first; removing it needs a device variable evaluator. Drops in.bfield and in.bfield.grid from the SPARTA_KOKKOS_EXACT skip list.

Dispatch by dynamic_cast instead, which is what UpdateKokkos::setup_surf_tally_copies() already does for the same reason (update_kokkos.cpp:2519), and give the fallback a message that names the actual problem.

Ten style pages never mentioned KOKKOS at all despite having a /kk class: compute gas/collision/grid, compute gas/reaction/grid, compute tvib/grid, fix dt/reset, fix emit/surf, fix surf/temp, read_surf, remove_surf, and the two field fixes. Four of those were already marked (k) in the command index, so index and pages contradicted each other. Add the standard accelerated-styles block to each. Section_accelerate.txt said only that a non-Kokkos fix or compute "will cause data to be copied back to the CPU incurring a performance penalty", which promises graceful degradation. Several styles instead stop the run, and the package imposes fixed per-style instance limits. Document both.

They are composites holding pointers to sub-regions, and Region::inside() is a host virtual, so they cannot be dispatched inside a kernel the way the four primitives are. Rather than add two more arms to the per-style switch, introduce a flat device representation: region_prim_kokkos.h defines a POD descriptor plus the device-side match, and KokkosBase gains flatten_region_kokkos(), which every Kokkos region implements -- a primitive emits one descriptor, a composite emits one per sub-region plus the combining op. A nested composite cannot be expressed as a flat list under a single op and is rejected by name rather than silently mismatching. This also removes the reason the emit fixes carried a KKCopy of each region style: they now hold one descriptor view, so the switch, the per-style copies and the KOKKOS_MAX_REGION_PER_TYPE / KOKKOS_MAX_TOT_REGION caps all go away. fix ave/histo and ave/histo/weight go through match_all_kokkos() and needed no change at all. nregion/list in RegUnion and RegIntersect become protected so the Kokkos subclasses can walk them.

First, reactions whose post-reaction collision model was adiabatic or impulsive were rejected at init. The Kokkos scatter only replicated NOMODEL/SPECULAR/DIFFUSE/CLL/TD. Add adiabatic_scatter() and impulsive_scatter() alongside the existing replicas, mirroring SurfCollideAdiabatic::scatter_isotropic() and SurfCollideImpulsive::impulsive() with the style's member state passed in from the reaction's flattened cmodel coeffs/flags -- the same coeff and flag layout SurfReactAdsorb::readfile_gs() writes (adiabatic 0/0, impulsive 11 coeffs / 4 flags). The init guard and cmodel_unsupported() are removed. Second, surf_react adsorb was usable only with surf_collide cll: the other six Kokkos surf_collide styles ended their surf_react dispatch with "this Kokkos surf_collide style supports only surf_react global/prob". Give specular, diffuse, adiabatic, piston, impulsive and td the same sr_kk_adsorb_copy path cll already had -- init dispatch, device react dispatch on sr_type 2, and the post_react/backup/restore loops -- so any Kokkos surf_collide style can now carry any Kokkos surf_react style.

First, it no longer falls back to the host whenever a custom per-particle attribute exists -- which is any run with fix ambipolar or fix vibmode, so "weight" plus ambipolar was paying a full particle+custom round trip with auto_sync on every timestep. The device path already builds a permutation map for the OnePart records; the custom vectors/arrays are now permuted through the same map. A cloned particle carries its source's index, so it inherits that particle's custom values, matching Particle::post_weight(). The same map argument applies to the sort/reorder path, which was likewise gated off whenever ncustom was non-zero, losing the locality optimization for those runs. It now permutes custom through d_sorted_id. Second, the serial host loop is bypassed entirely on non-EXACT builds. The loop is serial because its delete-by-swap-from-the-end makes the RNG draw order significant, which SPARTA_KOKKOS_EXACT needs to reproduce Particle::post_weight() bit-for-bit. But the physics is per-particle independent -- survive with probability ratio, or replicate to 1+nclone copies -- so post_weight_device() decides each particle in parallel, turns the per-particle copy counts into output offsets with an exclusive scan, and scatters once. No host round trip at all. EXACT builds keep the serial path, as compress_migrate() already does for the same reason. Along the way the EXACT path drops two per-timestep allocations: k_map and the maxlocal-sized d_newparticles are now members that only grow, and the weight ratio rides in the map entry so only one array crosses the bus instead of two.

The flattened call has no such fallthrough. With no region, nregion_prim is 0 and op is RKK_OP_NONE, so region_match_kk() read d_prims[0] of an empty view and rejected every candidate particle -- both emit fixes emitted nothing at all.

Unlike the per-grid and per-surf tally computes, these append one row per collision event, so the row count is not knowable before the kernel runs. Each Kokkos version claims a row with an atomic counter on a device append buffer and fills it in place. Overflow gets its own channel rather than truncating, since a short tally would silently corrupt dump tally output. A claim past the end of the buffer drops the row and raises a new scalar -- an 8th in UpdateKokkos, a 9th in CollideVSSKokkos -- which is checked in all four retry loops (one around the move kernel, three around the collision kernels). The handler grows every affected compute to what the failed attempt actually needed and repeats the pass, reusing the rollback that a reaction overflow already performs. Unlike a reaction overflow it needs no react/retry opt-in: nothing about the particle state forced it. Dispatch follows the existing pattern in both files: typed KKCopy lists selected by dynamic_cast, unused slots pointed at a temporary so the functor copies do not keep a stale reference. Note this is not yet demonstrated to produce correct tallies: no enabled example exercises these four computes (examples/tally_computes is absent from SPARTA_ENABLED_TEST_SUITES, which is why the audit found them untested). The suite confirms only that nothing else regressed -- 192 passed, 34 failed, the same 31 pre-existing plus 3 bfield.

the value enum and the switch (d_which[m]) body were never adapted. It therefore carried the collision enum {IDCELL,ID1,ID2,TYPE1,TYPE2,VX1PRE,...,VZ2POST} // 17 values where compute_gas_reaction_tally.cpp:26-28 defines {REACTION,IDCELL,ID1PRE,ID2PRE,ID1POST,ID2POST,ID3POST, TYPE1PRE,TYPE2PRE,TYPE1POST,TYPE2POST,TYPE3POST, VX1PRE,...,VZ2POST,VX3POST,VY3POST,VZ3POST} // 27 values Every column the user asked for was thus written from the wrong case label, and `reaction`, the pre/post id and type split, and the entire third-product column set had no case at all. examples/tally_computes/in.gas.reaction.tally requests 21 values including id3/post, type3/post and vx3/post, and its dump differed from the host in 28 rows. Replace the enum and rewrite the switch against gas_tally() at compute_gas_reaction_tally.cpp:144-272, including the jp == NULL / kp == NULL zero-fill branches the host has. This means using the third product, so drop the `/*kp*/` on the parameter -- CollideVSSKokkos already passes kpart at all four gas_tally_kk call sites (collide_vss_kokkos.cpp:1018,1430,1976,2232). The other three per-event tally computes were audited against their host enums and match; compute_surf_reaction_tally_kokkos.h only had a comment naming the wrong host file, corrected here. Compiles clean. The host-vs-KOKKOS dump comparison for the four tally_computes decks has not been re-run yet and is not claimed.

Each model is ~13 KB because it nests its own surf_react copies, so: sizeof(UpdateKokkos) = 224152 bytes, copied to the device per launch while a run was capped at two instances of each style -- a model with three wall temperatures is enough to hit "Kokkos currently supports two instances of each surface collide method". Raising the constants scales that 224 KB linearly, which is why they are removed rather than bumped. The models now live in device memory, one runtime-sized byte buffer per style, and the functor carries only the buffers and two index maps: sizeof(UpdateKokkos) = 42184 bytes KOKKOS_MAX_SURF_COLL_PER_TYPE and KOKKOS_MAX_TOT_SURF_COLL are deleted; the instance count is now bounded only by memory. The bytes are blitted in rather than constructed there, which is exactly what KKCopy::copy() already does (kokkos_copy.h:71) and is sound for the same documented reason: on device the models are only read, through KOKKOS_INLINE_FUNCTION members -- all nine collide_kokkos() are const -- so the vtable pointer is never used, and the View handles they carry are kept alive by the originals in surf->sc. Falling out of this: - the three device dispatch sites (3d surf, 2d surf, and the global boundary treated as a surface) collapse into one surf_collide_dispatch() - the nine-way strcmp ladder, written out four times with four separate sets of counters, becomes one SC_FOREACH list - SurfCollideVanishKokkos and SurfCollideTransparentKokkos gain backup() and restore(), which they lacked while the other seven styles had them. Their d_nsingle was only zeroed in pre_collide(), outside the retry loop, so a retried move added on top of the aborted attempt and inflated SurfCollide::nsingle, reported as Surface-collisions/particle/step. === C1 follow-up: the tally overflow retry never worked === DELTA is 4096 rows and the tally_computes decks tally ~100 rows per step, so no test had ever reached the retry path. Forcing it with DELTA cut to 8 gave two segfaults, one run emitting 100930 rows where the host has 32, and -- after a first round of fixes -- an infinite loop. Five defects: 1. The append counter was zeroed once per step in pre_surf_tally() / pre_gas_tally(), outside the retry loop, so a repeated attempt kept appending from where the aborted one stopped. This also double-counted rows on an ordinary reaction retry, which needs no small DELTA to hit. 2. backup()/restore() were gated on react_retry_flag, so with tally computes but no surface reactions an overflow retry re-ran the move over particles the aborted attempt had already moved. That is the segfault. The gate is now (react retry) || (a per-event tally compute is active). 3. post_*_tally() returned early on the discard path leaving ntally at the runaway device count, so dump tally read that many rows out of an array that never held them. It now zeroes ntally. 4. grow_after_overflow() reallocates the compute's row buffer, but the kernels read a KKCopy blitted at step setup, which still pointed at the old, too small buffer -- so the repeated attempt overflowed on the same row forever. 5. Rewinding to zero was wrong: the move kernel runs once per migration iteration (update_kokkos.cpp:601) with the tally accumulating across all of them, so zeroing discarded rows from earlier iterations. Replaced with mark_ntally()/rewind_ntally(), which rewinds only to where the current iteration started. === verification === - the four examples/tally_computes decks at 4 ranks, each dump compared to the host run as a per-timestep multiset (device rows append in atomic order, so row order is nondeterministic): all four identical to the host both at DELTA 8, where every step overflows and retries, and at the production DELTA 4096 - a deck with 8 surf_collide instances (5 diffuse, 3 specular), which previously aborted at the third diffuse: runs, and -sf kk matches the host exactly over 1000 steps in Np, Natt, Ncoll, Nscoll and Nscheck. It uses the last declared diffuse model, so this also exercises dispatch to a slot other than 0. ctest is still running at the time of writing and is not claimed here. No GPU was available in this environment, so the device path is unverified on an actual accelerator backend.

The audit flagged this as a possible performance gap; it is not one on CPU. Measured on 4 MPI ranks, Serial backend, 400k particles in a 20^3 grid over 400 steps, 2.65% of particles migrating per step, comparing the separately reported Comm section of the timing breakdown (median of 3 runs): comm serial comm threaded free molecular 0.228 s 0.246 s (+7.6%) with VSS collide 0.211 s 0.259 s (+22.5%) Loop time agrees in direction (3.47 s vs 3.95 s median for the collide deck). On CPU there is no host/device transfer for the host path to lose to, so the device path only adds the irregular-comm plan rebuild. The default stays as it is; the comment records the numbers so this is not re-litigated. Not measured: the OpenMP backend, or a deck dominated by migration.

The blocker was structural: the kernel built one group-contiguous row per cell (gcount/gstart/d_glist) before the attempt loop and never changed it, which reactions violate by rebinning, creating and destroying particles. Group lists are now mutable on device: d_glist (cell, group, k) -> plist index, one region per group, each sized to the whole cell since a reaction can move every particle into one group d_p2g (cell, plist index) -> group, k; the reverse map the host keeps in Collide::p2g, needed so a swap-remove can repair the moved entry's owner addgroup_kk()/delgroup_kk() mirror Collide::addgroup/delgroup (collide.h:157) including the swap-with-last order. That order is not cosmetic: rebinning changes which index a later random draw lands on, so a deviation diverges from the host rather than merely reordering output. The attempt loop is ported from Collide::collisions_group (collide.cpp:1255): recombination 3rd-body selection with recomb_boost_inverse (recomb_part3 was hard-coded NULL), ipart/jpart rebinning, jpart deletion via dellist plus the plist swap-remove and p2g repair, kpart append, and the group-too-small exits. find_nn_group() is ported from collide.cpp:2634, with per-pair nn arrays cleared per pair as set_nn_group() does and the same-group aliasing the host relies on. collisions_group() also gains the grow-and-repeat loop it never had, since it could not previously create or delete particles: d_retry, dellist growth, maxcellcount growth, and the react/extra pre-sizing, matching collisions_one(). The react and nearcp guards are removed. subcellflag stays (separate kernel). Ambipolar group collisions still assume static membership, so reactions there are still rejected -- but with a message naming that case rather than claiming group reactions are unsupported in general. Found while verifying, each only visible by running: - particle->nlocal was never written back after the retry loop, so every particle a reaction created stayed invisible to the host: KOKKOS Np sat at exactly 10000 for the whole run while the host grew to 13349 - on particle creation the host clears the new slot in BOTH nn arrays of the current pair (collide.cpp:1379-1390); clearing only one diverged, and only with reactions and nearcp active together - collisions_group_ambipolar() allocated the now-3d d_glist with two extents, so the third wrapped and it asked for 1.678e+07 TiB. Caught by examples/ambi/in.ambi.group, which is the only coverage of that kernel Verified at 4 ranks unless noted, comparing every stats column but CPU time: multigroup non-reacting (guard) identical multigroup + nearcp identical multigroup + reactions identical multigroup + reactions + nearcp identical examples/ambi/in.ambi.group, 1 rank identical examples/ambi/in.ambi.group, 4 ranks identical reacting ambipolar group aborts with the new message The reacting decks are two collision groups of 6-species air at 20000 K with examples/chem/air.tce, run with react/retry yes. MAXGROUP (16) is unchanged: gcount[MAXGROUP] is a per-thread device stack array, so lifting it needs scratch memory and is a separate change. ctest is still running at the time of writing and is not claimed here.

The reacting group collisions work widened d_glist to (cell, group, k), giving each group its own row, and updated the kernel's reads and its allocation -- but not this build loop. Group g was written at [offset, offset+gcount) of row g while every read (here, and in find_nn_group) indexes that row from 0, so with two or more non-electron groups each group after the first reads uninitialized entries. gstart was already dead: assigned here and read nowhere. examples/ambi/in.ambi.group cannot catch this. It defines exactly two groups, heavy and electron, and the electron group is skipped by the offset accumulation, so the one real group starts at 0 either way -- which is why the deck passed at 1 and 4 ranks while the bug was present. Verified with a 3-group variant of that deck (neutral / ion / electron): fixed binary, 1 rank host vs -sf kk IDENTICAL fixed binary, 4 ranks host vs -sf kk IDENTICAL buggy binary, 1 rank host vs -sf kk DIFFERS buggy binary, in.ambi.group IDENTICAL (masks the bug) ctest unchanged at 34 failures, same set as baseline.

They have been since the per-event tally computes landed, and the code 130 lines below dispatches both. - surf_collide_adiabatic_kokkos.cpp: the nsr > KOKKOS_MAX_TOT_SURF_REACT check reported "two instances of each surface reaction method", which describes the per-type cap, not this one. The other six styles say "a limited number of surface reaction methods"; match them. - delete eight #defines that nothing references: MAXGROUP in grid_kokkos.cpp and surf_kokkos.cpp, MAXSURFPERCELL, MAXACCUMULATE, MAX_TYPES_STACKPARAMS (a LAMMPS leftover) and three MAXLINE. The two dead MAXGROUP 32 shadowed the live MAXGROUP 16 in collide_vss_kokkos.cpp, so a reader grepping for the collision-group cap found the wrong definition first. - the AMD architecture list was spelled out twice: kokkos.cpp cleared atomic_reduction for GFX940/942/942_APU, and update_kokkos.cpp dispatched the ATOMIC_REDUCTION = -1 kernel for the same three. The counters are read back from the reduction result only when atomic_reduction is 0, so the two must agree or the statistics come from the wrong place. Define the condition once as SPARTA_KOKKOS_REDUCE_ARCH in kokkos_type.h. - fft2d/fft3d_kokkos.cpp: note that the KISS FFT device stack limit is raised for CUDA only. HIP has the same recursion and the same default-stack problem; the equivalent call is untested here, so record the gap rather than ship an uncompiled branch. Restrictions that are host parity, not Kokkos gaps: - react_qk_kokkos.cpp and react_tce_qk_kokkos.cpp reject recombination reactions and react_modify compute_chem_rates. So do ReactQK::init() and ReactTCEQK::init(), with the same conditions and the same message text -- neither model supports these on the CPU either. Say so, so the guards are not mistaken for something a Kokkos port could lift. - collide_vss_kokkos.cpp: the ambipolar+nearcp, ambipolar+subcell and nearcp+subcell checks in init(), and the subcell+multigroup check, all mirror Collide::init(). CollideVSSKokkos::init() does not call the host base, so it carries its own copies. Cite the host lines. Collide's subcell_alloc() refuses to allocate for multiple groups, so there is no host result a Kokkos version could reproduce. - the subcell+multigroup check in collisions() is unreachable, since init() has already aborted; keep it as an assert but give it the host's wording instead of a Kokkos-specific "does not (yet) support". ctest unchanged at 34 failures, same set as baseline.

All four now have /kk variants. - that region union and region intersect are rejected when used by a Kokkos-enabled fix. Both now have /kk variants. - that at most two instances of each surf_collide style may be defined. That cap is gone; surf_react is still capped at two. compute react/boundary is now the only style listed as rejected outright, which matches the code. Also: - Section_commands.txt: add the (k) marker to compute gas/collision/tally, gas/reaction/tally, surf/collision/tally and surf/reaction/tally. - region.txt: add union/kk and intersect/kk to the style list. - the four tally compute pages had no accelerated-styles section at all; add the standard block.

Two is easy to exceed -- three compute surf/collision/tally on different surface groups is an ordinary thing to want. The cap existed because each list was a fixed-size array of KKCopy<> held by value in UpdateKokkos, which is itself the functor handed to every move kernel. The lists now live in device memory instead, one runtime-sized buffer per type, with the objects blitted in -- the same memcpy KKCopy::copy() already performs (kokkos_copy.h:71), sound for the same documented reason: on device they are only read, through KOKKOS_INLINE_FUNCTION members, so the vtable pointer is never touched and the View handles stay alive in the originals that slist_active/blist_active hold. setup_surf_tally_copies() becomes count-then-blit, since the buffers must be sized before anything is written into them. pre_surf_tally() still runs in list order, so behaviour is unchanged. The five tmp_compute_*_kk placeholders are gone: they existed only to keep unused fixed slots from holding a stale reference-counted copy, and there are no unused slots now. sizeof(UpdateKokkos) goes from 42184 to 7976 bytes. That is recorded as a fact, not as a performance claim -- functor size interacts with occupancy and data locality in ways that are not predictable from the number alone, and nothing here has been measured on a GPU. This environment has none. This commit is self-contained: reverting it alone restores the fixed-size KKCopy arrays and the two caps, with no dependency on the other cap work. Verified: ctest 34 failures, same set as baseline. All four per-event tally decks IDENTICAL to host at 4 ranks. A new deck with three simultaneous compute surf/collision/tally instances -- which previously aborted with "Kokkos currently only supports two instances" -- runs, with all three computes matching host.

Both representations are now kept, selected by SPARTA_KOKKOS_FIXED_LISTS (-DSPARTA_KOKKOS_FIXED_LISTS, or the matching CMake option): default runtime-sized device buffers, no instance cap SPARTA_KOKKOS_FIXED_LISTS the original fixed KKCopy arrays and caps This applies to the update lists from the previous commit as well. A switch rather than a plain replacement because functor size is not a quantity where smaller is obviously better: shrinking it can raise occupancy while costing data locality, and occupancy is not throughput. Neither path has been measured on an accelerator -- this environment has no GPU -- so both are buildable and the comparison can be made on real hardware by rebuilding, without reverting anything. The 27 device dispatch sites are written once, against the UK_* and CVK_* accessors, so the kernel bodies are shared and cannot drift between the two modes. Only the declarations, constructor init lists and setup routines are duplicated. Recorded, as data and not as a performance claim: sizeof(UpdateKokkos) 42184 -> 7976 bytes sizeof(CollideVSSKokkos) 32248 -> 10480 bytes Verified: ctest 34 failures, same set as baseline. All four per-event tally decks IDENTICAL to host at 4 ranks, as is a deck with three simultaneous compute surf/collision/tally instances. Both modes compile; the SPARTA_KOKKOS_FIXED_LISTS path is compile-checked only, since ctest here exercises the default build.

Different order, different particles. fix emit/face solved this years ago with a twopass keyword (fix_emit_face.cpp:1233, dispatch at :481, implementation at :675), documented at doc/fix_emit_face.txt:219-227: with twopass the KOKKOS and non-KOKKOS versions "generate exactly the same set of particles", without it they are only "statistically similar". fix emit/face/file never got the keyword, which blocks a Kokkos port of it from ever matching the host. The intent was clearly there: examples/surf_collide/in.beam.td:6 already carries the copy-pasted comment 'The "twopass" option is used to match Kokkos runs' on a fix that cannot accept it. This adds the keyword to fix emit/face/file, mirroring the sibling exactly: the current perform_task() body becomes perform_task_onepass(), a new perform_task_twopass() hoists the two count draws into a first sweep over tasks, and perform_task() becomes the two-line dispatcher. The count pass is simpler than fix emit/face's -- this style has no prefactor/modulate and no np/npertask/nthresh branch, so it is unconditionally one uniform() per task (or per task-species). perform_task_twopass() was generated programmatically from the onepass body and then diffed against it, so the per-particle code cannot have drifted: the only differences are the hoisted first pass, the two count draws replaced by lookups, and the memory->destroy. Also documents twopass for fix emit/surf, which has supported it since fix_emit_surf.cpp:1835 with no mention anywhere in doc/fix_emit_surf.txt, and fixes FixEmitFaceFile::option()'s fall-through error, which reported "Illegal fix emit/face command" for a fix emit/face/file. No behaviour change when the keyword is not used, which is the point: - all 26 gold logs of the 13 decks using this fix (surf_collide, surf_react_adsorb and flowfile, all three in SPARTA_ENABLED_TEST_SUITES) still pass unchanged: 26/26. - with twopass set, examples/flowfile/in.flowfile diverges from its onepass run, confirming the keyword actually takes effect rather than being silently inert.

FixEmitFaceFile is entirely private and lacks the virtuals its sibling FixEmitFace has, so a Kokkos subclass cannot override the pieces it needs. Brings it in line with fix_emit_face.h: - struct Task moves to public, as fix_emit_face.h:38-62 has it, so the subclass can name the type - private: becomes protected: - create_task, grow_task, subsonic_inflow, subsonic_sort and subsonic_grid become virtual, matching fix_emit_face.h:97-103 - init() and the destructor are marked override Also adds the missing "if (copymode) return;" guard to ~FixEmitFaceFile(). Every sibling has one -- fix_emit_face.cpp:117, fix_emit.cpp:63, fix.cpp:74 -- and without it a Kokkos functor copy's destructor would free the file mesh and the per-task arrays while the original is still using them. The guard is inert today because nothing sets copymode on this class yet, which is exactly why it is safe to add ahead of the subclass. No behaviour change: access specifiers, virtual dispatch on methods that have no overriders yet, and a guard that cannot fire. ctest 34 failures, same set as baseline.

That commented code could not simply be restored: it declared locals that shadow the member Views the functors read, so it would have compiled and silently accumulated from a default-constructed device view. The FIX branch now has two paths, mirroring FixAveGrid::end_of_step() (fix_ave_grid.cpp:541-552): - device: if the fix exposes a usable KokkosBase::d_vector_grid / d_array_grid, assign the member view and launch the existing TagFixAveGrid_Add_fix_vector / _array functors, which were already fully implemented and simply unused - host fallback: otherwise add the fix's host per-grid output into the tally and push it to the device The gate is a non-null device view, NOT fix->kokkos_flag. fix field/grid/kk deliberately clears kokkos_flag (fix_field_grid_kokkos.cpp:32) because its variable evaluation is host-only, yet it does publish a valid d_array_grid; conversely fix ave/grid/kk clears it in its PERGRIDSURF flavor precisely because the device views are unallocated there. Only the view is accurate. Separately, this fixes a pre-existing bug in the VARIABLE branch. Variable::compute_grid() is called with sumflag = 1 (variable.cpp:867), so it ADDS into the host tally -- but earlier values in the same command accumulate on the device and k_tally is not marked device-modified until after the value loop. The branch therefore summed into stale host data and then pushed it over the device accumulation. A fix ave/grid command mixing a compute and a variable silently lost the compute's contribution. Both the new fallback and the VARIABLE branch now pull the tally down before adding to it. Verified: ctest 34 failures, same set as baseline.

The device representation was a flat array of RegionPrimKK plus a single boolean op, which cannot express nesting. Replaced with a postfix (RPN) token stream evaluated with a small fixed-depth boolean stack: struct RegionTokenKK { int type; // PRIM | UNION | INTERSECT | NOT RegionPrimKK prim; }; A primitive emits one PRIM token, so its cost is unchanged and region_match_kk() still short-circuits on ntoken == 1 before the stack is even declared. A composite emits its sub-streams left-folded with its op, plus a single NOT token when its own interior is 0 -- which is exactly the !(hit ^ interior) the host applies. Because sub-regions contribute whole sub-streams, nesting is just concatenation. RegionPrimKK and region_prim_match_kk() are untouched, so primitive matching still follows Region::match()'s !(inside ^ interior) convention exactly. Depth is bounded at RKK_MAX_STACK = 16 and checked on the host when the region is flattened; a tree too deep is rejected with a message naming the depth it needed, never silently truncated. Only right-nesting consumes depth: flat and left-nested composites stay at depth 2, so 15 levels of right-nesting fit. Every consumer still tests region_flag before evaluating, and region_match_kk returns 0 for ntoken <= 0 rather than reading element 0 of an empty view. That is deliberate: an earlier change in this area shipped a bug by dropping that guard, which made every emitted particle be rejected when no region was defined. All four kernel sites were re-read individually. Verified: the evaluator was checked against a reference transcribed from RegUnion::inside(), RegIntersect::inside() and Region::match() over 4000 random trees (5 deep, mixed ops, exterior senses at every node, all four primitive styles) x 200 points = 800,000 points with zero mismatches, plus the fast path, the empty case, and the depth accounting. ctest 34 failures, same set as baseline. Not verified: compilation under nvcc/hipcc, and the register cost of the 16-int stack on a GPU. No accelerator was available.

It dimensioned per-thread arrays inside the two group kernels -- int gcount[MAXGROUP], plus gcursor[] in the ambipolar one -- so it could not simply be raised. Both group kernels are one work item per grid cell, so there is already a deterministic, contention-free index available: icell. The arrays become Kokkos::View of (nglocal, ngroups), sized next to d_nattempt_pair with the same extent guard, and every use goes through d_gcount(icell,g). No UniqueToken is involved -- it would add acquire/release cost and nondeterminism for an index that is already unique per work item. addgroup_kk()/delgroup_kk() drop their int* gcount parameter rather than take a row pointer. That is deliberate: DeviceType::array_layout is LayoutLeft on CUDA/HIP, so a row of a 2-D View is strided, not contiguous, and &d_gcount (icell,0) would have been silently wrong on a GPU. With LayoutLeft icell is stride-1, which is the coalescing the per-thread array gave. No compile-time fallback is kept here, unlike the surf_react and tally-list cap lifts. gcount is indexed by ig/jg/newgroup -- all runtime values -- so it could never be register-resident and was already in local memory; the change is local memory to global memory with equivalent coalescing, not registers to memory. There is also no accessor seam here for the two paths to share, so keeping both would mean duplicating the kernel bodies. Memory is nglocal*ngroups ints, exactly 1/d_plist.extent(1) of what d_glist already allocates: if d_glist fits, this does. No physics or RNG change. ctest 34 failures, same set as baseline. Note that ngroups > 16 has never been exercised by any deck, so the lift itself is untested beyond the suite continuing to pass.

It dimensioned double prob_value[SRA_KK_MAXPERSPECIES], a per-thread array inside react_kokkos(). react_kokkos() is called from surf-collide kernels that run per particle, not per cell, so unlike the MAXGROUP case there is no small stable index to key scratch on -- per-particle scratch would be nlocal x nmax. This one therefore uses Kokkos::Experimental::UniqueToken to get a per-concurrent-thread slot into a (tok.size(), nmax) View. Both paths are kept, selected by SPARTA_KOKKOS_FIXED_LISTS, and that matters more here than anywhere else in this series: a 16-element array indexed by a loop counter plausibly IS register-resident today, so replacing it with global memory may cost performance on a GPU, and acquire/release is not free either. tok.size() is large on an accelerator, so tok.size()*nmax doubles is real memory. Nothing here has been measured on a GPU -- this environment has none -- so the fixed-size path remains one flag away. RNG consumption is unchanged: the token acquire/release brackets the existing rand_pool get_state/free_state and no draw is added, moved or made conditional. ctest 34 failures, same set as baseline.

Two is easy to exceed: distinct reaction models on different surface groups is ordinary. They dimensioned fixed KKCopy arrays nested inside compute_surf_kokkos and all seven surf_collide styles, which is why each surf_collide object was 13 KB. Same treatment as the tally compute lists in 8cca8f80 and 0de217c7: per-type runtime-sized device byte buffers, models blitted in exactly as KKCopy::copy() does (kokkos_copy.h:71), with both representations kept and selected by SPARTA_KOKKOS_FIXED_LISTS. The device dispatch sites are written once against accessor macros so the two modes cannot drift. The pre_react/post_react/backup/restore lifecycle still runs on each model in the same order as before. sizeof(SurfCollideDiffuseKokkos) goes from 13056 to 3192 bytes, which also shrinks by 4x the runtime buffers UpdateKokkos allocates for the models. Recorded as data, not as a performance claim: nothing here is measured on a GPU, and functor and buffer sizes trade against occupancy and locality in ways the byte count alone does not predict. That is what the switch is for. ctest 34 failures, same set as baseline.

Modelled on fix_emit_face_kokkos: a count kernel, an offset_scan, a generate kernel, a compaction lambda, then a host loop for update_custom. Like its sibling it overrides perform_task(), so the Kokkos path is always two-pass -- the scan must know every task's insertion count before candidate arrays can be sized, which is exactly why the host needed the twopass keyword to match. Adds a guard the sibling lacks: #ifdef SPARTA_KOKKOS_EXACT if (!twopass) error->all(FLERR,"... requires the twopass keyword ..."); #endif fix emit/face/kk is silent when twopass is unset and simply produces different particles from the host. That is tolerable in a normal build but not under SPARTA_KOKKOS_EXACT, whose entire purpose is bit-for-bit agreement: the build would be asserting parity while the fix quietly broke it. Outside EXACT this one is silent too, matching the sibling. Two host-side hazards handled, neither of which the sibling has: - FixEmitFaceFile::init() delete[]s and re-new[]s the per-task fraction, cummulative, vscale and ntargetsp arrays for surviving tasks. Those are now DualView rows, so on a second run command that would be heap corruption. init() sizes the views and zeroes ntask before delegating. - per-task fraction/cummulative/vscale are per-task pointers here, not the mixture-wide arrays the sibling has, because file values vary per face. They are DualViews whose host rows are what interpolate() already writes into, so the file mesh stays host-side and is flattened once, not per step. Deck and gold log churn, deliberate and unavoidable: twopass is added to all 16 fix emit/face/file lines across the 13 decks, and their 26 gold logs are regenerated, exactly as the fix emit/face decks already do. Without it those decks would trip the new EXACT guard. The regenerated logs are as portable as the ones they replace: all 26 passed before this change, so this build's host path already agreed with the previous references; only the RNG ordering moved. Verified: - in.flowfile under -sf kk is IDENTICAL to the host twopass run - the EXACT guard fires with an actionable message when twopass is absent - all 26 affected tests pass under -sf kk against the regenerated logs - full ctest 34 failures, same set as baseline Not covered: no example deck sets a press column, so the subsonic device path ships with zero test coverage. Other RNG-parity assumptions that the passing decks do not exercise are listed in the review notes; the subsonic moment-sum ordering (sorted_kk vs Particle::sorted) is the most significant.

The other four styles (adiabatic, cll, impulsive, td) already had it, and so does the host -- SurfCollideDiffuse::collide() gates on "if (isr >= 0)" (surf_collide_diffuse.cpp:146). REACT is a property of the whole kernel launch, not of the element being hit, so isr is -1 whenever a surface element or box face shares a surf_collide instance with one that has a reaction model but has none itself. KK_SR_TYPE(-1) then read out of bounds and dispatched on whatever type tag came back. This was latent while the type map was a fixed array held by value in the functor -- index -1 read an adjacent member and happened not to select a branch. Once the map became a runtime-sized device view the same read went off the front of the allocation and selected an uninitialized model, segfaulting inside its random pool. Reproducer, which no example deck covers: a 2d box with surf_collide sc diffuse 300.0 1.0 surf_react rb prob air.surf bound_modify ylo collide sc bound_modify yhi collide sc react rb segfaults under -sf kk and runs clean on the host. With the guard the two agree bit for bit.

UpdateKokkos now partitions its active boundary tally computes into two typed lists rather than one, since the two styles have different device state. Its device accumulator is a ScatterView, so the tally is correct with or without atomics. ComputeReactBoundary::~ComputeReactBoundary() gains the "if (copy || copymode) return;" guard every sibling already has (compute_boundary.cpp:85). Without it the functor copy's destructor frees the arrays the live compute still owns -- with the fixed-list layout that is an immediate "free(): invalid pointer" abort, because the Kokkos-only ComputeReactBoundary(SPARTA*) constructor never initialises those pointers. compute reduce/kk Reduces on the device whenever the input has a device-resident source: the explicit per-particle attributes, per-particle and per-grid custom attributes, and the per-particle or per-grid output of a compute or fix that has a /kk variant. Per-surf inputs, particle/grid-style variables, and non-Kokkos compute or fix output fall back to ComputeReduce's own implementation after the host arrays it reads are synced. ComputeReduce's destructor has no copymode guard and manages a dozen host allocations, so this style must never be handed to a Kokkos functor by value. Every kernel is therefore a KOKKOS_LAMBDA over local copies of the views it touches, and the header says so at the declaration site. Verification, all at 4 ranks and 1 rank, host vs -sf kk, bit for bit: - a 2d box with surf_react prob on one face and a per-step compute react/boundary: the nonzero tally rows agree exactly - a deck exercising all eight reduce modes, the compute/fix/variable/ custom input forms, and the subset and replace keywords: all 19 output columns agree exactly ctest: 34 failures out of 226, the same 34 names as the pre-existing baseline (set difference empty in both directions). Docs: (k) markers in Section_commands.txt, accelerated-styles boilerplate on both pages, a note on which reduce inputs run on device, and two stale paragraphs in Section_accelerate.txt corrected -- compute react/boundary is no longer the style that stops a run, and the per-style instance caps now exist only in a -DSPARTA_KOKKOS_FIXED_LISTS build.

This was the last of the six host-side instance caps still live in a default build; the other five already move their models into runtime-sized device byte buffers. Same treatment here: the fixed KKCopy array becomes a DAT::tdual_char_1d sized at each perform_task(), models are blitted in as KKCopy::copy() does (kokkos_copy.h:71), and the one device dispatch site reads through a FES_SLIST() accessor so the kernel body is written once for both layouts. Building with -DSPARTA_KOKKOS_FIXED_LISTS restores the fixed array and the cap, and its error message now says so. No example deck covers this path at all -- in.emit.surf.normal has its "compute csurf surf" line commented out -- so verification used a new deck: one fix emit/surf driving three compute surf instances (nflux, mflux, press) through fix ave/surf. Under -sf kk that used to stop the run; it now completes and all three reduced tallies match the host bit for bit at 1 and 4 ranks. ctest: 34 failures out of 226, the same 34 names as the baseline.

The previous Kokkos kernel assumed group membership and the electron list were static within a timestep, so CollideVSSKokkos:: collisions() rejected the combination outright when a react style was defined. The support matrix is now identical to the host's. Collide::collisions() (collide.cpp:391-451) reaches exactly seven leaves, and its init() restrictions (collide.cpp:164-176 and :274-276) make the rest unreachable: ambipolar subcell nearcp groups host routine KOKKOS --------- ------- ------ ------ --------------------- ------ no yes no 1 collisions_one_subcell yes no no no 1 collisions_one<0> yes no no no >1 collisions_group<0> yes no no yes 1 collisions_one<1> yes no no yes >1 collisions_group<1> yes yes no no 1 collisions_one_ambipolar yes yes no no >1 collisions_group_ambi.. yes <- this commit each crossed with reactions on/off and gas tally on/off. The four combinations still refused are refused by the host too, and CollideVSSKokkos::init() now mirrors each one condition-for-condition and message-for-message rather than claiming a Kokkos limitation: ambipolar+nearcp, ambipolar+subcell, nearcp+subcell, and subcell with more than one group. The new work over the plain group path is the electron list. Reactions move particles between elist and plist in four ways, and the host's ordering of those mutations is load bearing -- rebinning changes which index a later random draw lands on -- so each is placed exactly where Collide places it: ionization two neutrals -> ion + electron: append to elist, then let the delete block drop the stale plist and group entries exchange ion + electron -> two neutrals: the electron becomes a real particle, appended to plist and its group recombination ion + electron -> one neutral: swap the last electron down over the consumed one kpart a created electron goes to elist and is removed from the particle list; any other product is appended to plist The electron group is the one place addgroup_kk()/delgroup_kk() are not used. The host maintains glist[egroup][k] == k as an invariant (electrons are appended in order and removed by swapping the last one down) and both the host and this kernel index elist by the drawn index directly, so only the count is tracked. Writing that row would also need a bound the elist capacity does not share, since maxelectron can exceed the per-group row width. Growth follows the established pattern: the kernel raises d_retry, bumps the relevant counter and returns; the host reallocates and repeats the pass. d_gcursor is deleted -- the two-pass list fill it existed for is gone, since the lists are now built with addgroup_kk(), which keeps d_gcount and d_p2g in step. Verification, host vs -sf kk, at 1 and 4 ranks: - a new 2d multigroup ambipolar deck with react tce, 600 steps, 518659 collisions and 389 gas reactions: every stats column identical - the same deck at 300 steps is added as examples/ambi/in.ambi.group.react with gold logs; ambi is in SPARTA_ENABLED_TEST_SUITES, so this is live CI coverage - examples/ambi/in.ambi.group, the existing non-reacting guard, still matches its committed gold logs at both rank counts - a multigroup variant of examples/ambi_3body/in.ambi_3body, whose chemistry is an ion-third-body dissociation and recombination: 4467 and 4575 gas reactions, every column but cpu identical Coverage gap, stated plainly: examples/ambi/air.tce defines no recombination reactions, so the CI deck exercises dissociation, exchange and ionization but not the recombination branch. Recombination was verified only by the scratch ambi_3body variant above, which is not in examples/ -- the ambi_3body suite is not in SPARTA_ENABLED_TEST_SUITES. ctest: 34 failures out of 226, the same 34 names as the baseline. The comment in examples/ambi_3body/in.ambi_3body claiming a single-group mixture is required because KOKKOS "currently supports only single-group collisions" is corrected; it has not been true for the plain group path and is no longer true for the ambipolar one.

Both did that with a nested scalar loop over every element before syncing. The loop was avoidable. Memory::create(TYPE**&,n1,n2) (memory.h:114-127) makes one contiguous allocation of n1*n2 and points each row pointer into it, and tdual_float_2d_lr is LayoutRight, so the host buffer and the view already have the same element order. Wrap the existing buffer in an unmanaged host View and issue a single deep_copy instead. On a host backend a DualView's two views are the same memory, so the old loop was pure per-invocation overhead in front of a no-op sync; on a GPU it was an extra host-side pass in front of the one H2D transfer that has to happen either way. fix field/particle runs every timestep (update.cpp:672), so it is the one that matters; field/grid gets the same treatment because the code is identical. The copy needs a leading-row subview, not the whole view: the realloc guard is grow-only (extent(0) < nlocal), so the destination keeps a high-water-mark row count after the particle count drops, and Kokkos::deep_copy throws on any extent mismatch (Kokkos_CopyViews.hpp:1163). Without the subview a run aborts on the first step a particle leaves the box: Deprecation Error: Kokkos::deep_copy extents of views don't match: field/particle/kk:array_particle(10000,2) (9882,2) A leading row range of a LayoutRight view is still contiguous, so the subview costs nothing at runtime. A static_assert records that the wrap assumes F_FLOAT is double. Neither in.bfield nor in.bfield.grid exercises this: both hold Np at exactly 10000, so nlocal never shrinks and the extent mismatch never arises. Verification therefore used those two decks plus outflow variants where Np falls from 10000 to 141. All four decks match the host bit for bit at 1 and 4 ranks. Also drop a comment in compute_reduce_kokkos.cpp that justified spelling a type as SPARTA_FLOAT by citing an "SPA_PRECISION==1 build". No such build option exists -- SPA_PRECISION is defined only in kokkos_type.h with a default of 2 and is never set by the build system. The reason the type has to be spelled out is template deduction, which the comment now says on its own.

Each was verified against the source before being acted on; two are correctness, three are waste. 1. ParticleKokkos seeded weight_rand_pool in the constructor initializer list with 12345 + comm->me. Every other Kokkos class does the same and is fine, because they are styles the input script creates long after SPARTA::create() has returned. ParticleKokkos is built by create() itself, at sparta.cpp:484, three lines BEFORE comm exists (:487), and comm is not NULL-initialized -- so this dereferenced an uninitialized pointer at startup. The member is #ifndef SPARTA_KOKKOS_EXACT, and every build made while this branch was developed set EXACT, so it was never compiled. A non-EXACT build segfaults immediately: examples/axi/in.axi, which uses "weight cell radius" and so reaches post_weight_device(), gives rc=139. The pool is now seeded on first use, with the same seed; that deck then runs clean at 1 and 4 ranks. 2. grow_tally_kokkos() in all four per-event tally computes used MemKK::realloc_kokkos, which drops the old allocation and allocates WithoutInitializing. The mark/rewind retry protocol requires the rows below ntally_mark -- written by earlier migration iterations of the same step -- to survive, since rewind_ntally() only takes the count back to the mark and the re-run appends from there. Use DualView::resize, which preserves contents, as memoryKK->grow_kokkos already does. No deck reaches the combination: maxtally is a high-water mark that persists across steps, so by the time a step has more than one tallying migration iteration the buffer already fits the whole step. Probing in.surf.collision.tally at 4 ranks with DELTA forced to 8, then to no headroom at all, gave 13 grows, every one with ntally_mark == 0, against 40 nonzero marks elsewhere in the same run. This is a latent hazard closed on principle, not a reproduced failure, and the comment at the site says so. 3. TagCollideCollisionsGroup was the only one of the five collision kernels without the "if (d_retry()) return;" early-out. Once any cell raises retry the whole pass is rolled back, so the rest of the grid was running a full reacting pass whose results were then discarded. 4. collisions_group() freed d_nn_igroup/d_nn_jgroup at the end of every call, so the grow-only guard reallocated two nglocal x maxcellcount int arrays on every timestep of every nearcp multigroup run. They are owned by this class rather than borrowed from grid or particle, so they are now kept and reused. Safe because the kernel clears the entries it uses at the start of each group pair, mirroring Collide::set_nn_group(), so it never reads stale values. 5. backup() allocated a fresh full-size particle buffer on every call, and restore() freed it. backup() runs once per attempt of the retry loop and the loop runs once per migration iteration, so a step churned that allocation several times whenever a per-event surf tally compute was active. The buffer is now reused across a step's iterations and released by free_particle_backup() once migration is done, so peak memory is unchanged. Verification: ctest 34 failures out of 228, the same 34 names as the baseline. All four tally computes still match the host bit for bit at 4 ranks, compared as a per-timestep multiset. A non-EXACT build was made and exercised for the first time. One further finding is left alone: output.cpp:302 (and :389, read_restart.cpp:467, read_surf.cpp:2344) size an snprintf with strlen(restart1) taken after *ptr='\0' has truncated the string at the wildcard, so restart filenames silently truncate when the timestep plus suffix exceeds 15 characters. It is real, but it predates this work and is unrelated to the KOKKOS port.

Neither is related to the KOKKOS port; they are fixed here at the maintainer's request after a review of the branch surfaced the first one. 1. Restart/surf filename truncation (4 sites) output.cpp:302 and :389, read_restart.cpp:467, read_surf.cpp:2344 size an snprintf with strlen() taken AFTER *ptr = '\0' has truncated the name at its "*" wildcard. Taken after, that is the length of the prefix, not of the buffer, so the tail of the filename is silently cut off. The buffers themselves are correctly sized -- the allocations use the untruncated length -- so this is truncation, not overflow. It bites once (timestep digits + suffix length) > 15. With a "tmp.restart.*.equil.gz" pattern that is any timestep from 1,000,000: old: tmp.restart.1000010.equil.g <- the "z" is gone new: tmp.restart.1000010.equil.gz Verified in SPARTA both ways by reverting output.cpp and rebuilding, and the wildcard read path round-trips: write at step 1000010, then "read_restart tmp.restart.*.equil.gz" resolves and loads it. Fixed by computing the length once, before the truncation, and using that single value for both the allocation and the bound. In the two file_search() cases outfile belongs to the caller, which allocates new char[strlen(arg[0]) + 16], so that is the bound; a comment at each site records where it comes from. 2. Unbounded sprintf into fixed-size buffers (125 sites, 36 files) The pervasive idiom char str[128]; sprintf(str,"Cannot open VSS parameter file %s",filename); error->all(FLERR,str); overflows whenever the interpolated string is long enough, which a deep directory path easily is. Demonstrated with a 200-character path in "collide vss": *** buffer overflow detected ***: terminated (SIGABRT) glibc's _FORTIFY_SOURCE caught it here; unfortified, it is a silent stack smash. Every one of these is now snprintf(buf,sizeof(buf),...), so an over-long message is truncated instead. The same reproducer now prints an ordinary error and exits 1. 19 of the 125 sites are in files where the same identifier is used both as a fixed array and as a char* elsewhere. sizeof() on a char* would yield 8 and manufacture the very bug being fixed, so those were excluded from the mechanical pass and each was confirmed by hand to be a fixed array declared on the preceding line. Four related classes were searched and found clean, so they are recorded here rather than left to be re-investigated: snprintf bounds that differ from their allocation (none); strcpy/strcat into fixed buffers (8 hits, all either explicitly guarded -- balance_grid.cpp:132, sparta.cpp:541 -- or false positives on a heap char*); new char[strlen(x)] missing its +1 (none); and strncpy with no terminator (surf_react_adsorb's state_reactants/state_products are new char[1] read only via [0], never as C strings). Behaviour change worth noting: an error message longer than its buffer is now truncated rather than overflowing, so a few diagnostics can lose their tail. That is the intended trade.

From e83a483efb21cafe6cbc0c8ec9495677d1e1134c Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 22 Aug 2026 14:25:11 +0000 Subject: [PATCH 45/61] tests: close the highest-value CI coverage gaps A style-level sweep of the 33 enabled suites (126 decks) against every registered style found that 13 of 28 computes, 7 of 25 fixes, 4 of 6 regions and 2 of 9 surf_collide styles appear in no enabled deck. This closes the gaps that cost nothing or nearly nothing, and where bugs actually hid during the KOKKOS work. Suites enabled, no new decks needed: tally_computes 4 decks, 8 gold logs and 8 gold dumps, all already committed and simply not listed. These are the four per-event tally computes, where the overflow/retry work found five defects. ambi_3body deck already present; gold logs generated here. Coverage folded into existing decks, so no new files: in.free compute boundary. This was the single worst gap: no deck anywhere in examples/ used compute boundary, and it is the style whose KOKKOS boundary-tally path carried the unchecked downcast that made the baseline segfault. Values are n/nwt/press, not ke or shx -- every face here is specular, so energy flux and shear are identically zero and could not detect anything. in.relax_const compute eflux/grid, pflux/grid, sonine/grid and ke/particle, reduced to scalars. ke/particle lives here rather than in in.free because free molecular flow never changes a particle velocity, so any reduction of it is constant for the whole run. in.emit.surf.normal uncommented the compute surf + fix ave/surf lines that were already sitting there. This is the only deck that drives a surf tally compute from fix emit/surf. New deck: examples/free/in.free.restart No test read a restart file. All four examples/custom/in.*.restart decks are in SPARTA_DISABLED_TESTS marked "# Failing", and none of them uses the "*" wildcard anyway -- they use "%" fileper. So ReadRestart::file_search() had no coverage at all. The deck drives all three filename-substitution paths in one run: "restart" (Output::write), "write_restart", and "read_restart" through the wildcard search. It is a real regression test for the truncation fixed in the previous commit, not a synthetic one: reverting output.cpp and read_restart.cpp and rerunning gives tmp.rtp.np1.20.equil.restar (truncated) ERROR: Cannot open restart file tmp.rt.np1.20.equil.restar rc=1 The ".equil.restart" suffix is deliberately long, because a name is truncated only when (timestep digits + suffix) exceeds 15; a short suffix would let the bug through. The name carries the MPI rank count via extract_setting(world_size) because ctest runs the mpi_1 and mpi_4 copies of a test concurrently in one shared suite directory -- the same race that keeps in.exp2imp.axi.spherecone.readback disabled. Two tests were passing vacuously: relax_const and relax_variable are enabled but shipped no gold log at all, so the harness created a reference on first run and compared it to itself. Both now have real gold logs. All four modified/new decks match the host bit for bit at 1 and 4 ranks. Superseded gold logs are git rm'd rather than left alongside, since the harness takes glob("log.*..")[0] and two dates would make the reference ambiguous.

786680520aab5ae173085d25a9600cbd102cb188 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 22 Aug 2026 15:06:25 +0000 Subject: [PATCH 46/61] Initialize the Compute output pointers, fixing a heap corruption Compute::Compute() set every flag and counter but left the eight output pointers -- vector_particle, array_particle, vector_grid, array_grid, vector_surf, array_surf, vector_surf_tally, array_surf_tally -- entirely uninitialized. Each subclass assigns only the ones it uses, and usually only on its first invocation, so a compute that is defined in the input script but never consumed carries garbage in the rest. ComputeKEParticleKokkos::~ComputeKEParticleKokkos() passes vector_particle to memoryKK->destroy_kokkos(), which tests it against NULL (memory_kokkos.h:108) and then free()s it when the DualView has no device allocation. For a compute ke/particle that nothing reads, that is a free() of an uninitialized pointer. The failure is badly misleading. The run itself is completely correct -- all 201 stats rows match the gold log exactly -- and the process then aborts during MPI_Finalize with "corrupted size vs. prev_size" or "double free detected in tcache 2", inside OpenMPI's own cleanup. The corrupted heap is only detected long after the damage is done, so the backtrace points at libmpi and not at SPARTA at all. valgrind names it exactly: "Conditional jump or move depends on uninitialised value(s)" at memory_kokkos.h:109, called from the destructor. Found by adding examples/free/in.free.restart and the compute ke/particle line in examples/relax_const/in.relax_const -- the first decks in the repository to declare that style. It has no /kk coverage anywhere in examples/, which is why a bug this old survived. Two smaller fixes go with it: ComputeKEParticleKokkos's destructor now clears ke as well as vector_particle. The host aliases the two (compute_ke_particle.cpp:71 "vector_particle = ke") and ~ComputeKEParticle() frees ke, so once the Kokkos destructor has released that allocation the base destructor would free it a second time. ke moves from private to protected in compute_ke_particle.h so the subclass can clear it. After the fix, valgrind reports 0 errors from 0 contexts on a deck that previously corrupted the heap.

Each was verified before and after the change. 1. compute property/surf read past cglobal[] with a subset surf group cglobal[] was allocated with nchoose entries and filled with only the owned elements that are in the surface group, but 27 of the 29 pack_* methods index it as cglobal[i] for i < nsown. Whenever a group is a strict subset -- nchoose < nsown -- those loops read past the array and then index lines[]/tris[] with whatever came back. The contract is nsown, not nchoose: vector_surf/array_surf are allocated nsown rows here and every consumer reads surf->nown rows of them (fix_ave_surf.cpp:215). The "else buf[n] = 0.0" branch in each pack method exists precisely to zero the rows whose element is outside the group, which only makes sense when the loop covers all owned elements. So cglobal is now a plain local -> global map with nsown entries and the pack loops are left alone -- one setup block rather than 29 methods. 456f0be9 had changed pack_id alone from nsown to nchoose. That is the wrong direction: it left pack_id filling nchoose rows of an nsown row buffer while every other column filled nsown. Reverted. On a deck with 24 of 50 surfs in the group, valgrind on the old code reports "Invalid read of size 4" at pack_v1x, 18 errors from 2 contexts, and the run segfaults. After the fix: 0 errors, and the output is unchanged. 2. Grid::id_num2str assumes a 128 byte caller buffer It bounds its snprintf with "128 - offset" and guards at offset >= 110. dump.cpp and dump_grid.cpp were widened to char[128]; VTK/dump_grid_vtk.cpp:264 was missed and still passed char[32]. The bail-out also left the string unterminated, because the previous iteration overwrites the terminating NUL with '-'. Both fixed. 3. Ambipolar electron-list retry seeded from the wrong value Both ambipolar launchers set h_maxelectron() from the Collide member maxelectron, which starts at 0, while the kernel overflows against d_elist.extent(1). Each retry therefore bumps the request by DELTACELLCOUNT from zero and re-runs the whole pass, converging only after dozens of wasted sweeps. Seed from the allocation instead. collisions_group_ambipolar inherited this by copying collisions_one_ambipolar verbatim; both are fixed. 4. Stale tally-overflow flag in the collide retry path The attempt-top reset in the five CollideVSSKokkos launchers zeroes h_retry, h_maxdelete, h_maxcellcount, h_part_grow, h_ndelete and h_nlocal but not h_tally_overflow. That branch cannot bulk-zero h_scalars the way UpdateKokkos does, because it reads maxdelete, maxcellcount and nlocal back out of it. A pass that raised both flags pushed a stale 1 back to the device and drew a spurious grow_tally_computes() plus a wasted sweep on the next attempt. UpdateKokkos was reported as having the same problem and does not: its retry branch does deep_copy(h_scalars,0) and h_tally_overflow is a subview at index 7, so it is already cleared. Left alone.

Neither has a deck anywhere in examples/. 1. stats[2], the minimum of all input values, was reported as 0. Two bugs compounded here. The reducer's value was default constructed, which leaves min_val and max_val at 0, so bin_one()'s "if (value < mm_v.min_val)" could never fire for positive input. The host sets stats[2] = BIG and stats[3] = -BIG for exactly this reason (fix_ave_histo.cpp:552-553). Initializing it exposed the second: the value was a local in end_of_step(), so it started over on every sample and the reported minimum was that of the final sample alone. The host resets stats[2]/stats[3] only when irepeat == 0 and accumulates across the whole Nrepeat window (fix_ave_histo.cpp:549-553). It is now a member, reset in that same branch. 2. fix ave/histo/weight/kk ignored the weight for scalar-mode inputs. The weight subclass applies weights correctly in its per-particle and per-grid device kernels, which call the three-argument bin_one with d_weights. Scalar inputs -- a compute, fix or variable global scalar -- are binned by the base class, whose two-argument overload hardcoded a weight of 1. The host injects the scalar weight by overriding the single-value bin_one (fix_ave_histo_weight.cpp:310-312); that overload is not virtual here and the call sites are in the base class, so it reads weightflag/weight directly instead. weightflag is 0 for plain ave/histo, which leaves the weight at 1 and that path unchanged. Verified on a deck driving both styles from a compute temp in scalar mode, at 1 and 4 ranks. Before: min 0 vs the host's 497.25014, and a weighted count of 4 vs the host's 1991.0328. After: every column matches the host exactly.

All three match the host bit for bit at 1 and 4 ranks. The remaining uncovered styles were exercised too, but as scratchpad decks rather than committed examples, since they are diagnostics and bookkeeping rather than physics worth a permanent deck: fix ave/histo, ave/histo/weight, ave/time, controller, halt, print, temp/global/rescale -- all seven verified against the host, and this is what turned up the two fix ave/histo bugs in the preceding commit compute distsurf/grid, react/surf, react/boundary -- host and device agree; the two per-event tally computes read 0 at most output steps by construction, since they reset on every invocation react tce/qk is deliberately NOT given a deck. On an identical setup it produces zero reactions where react tce produces 627 and react qk produces 691. ReactTCEQK::attempt_tce uses a different probability expression from ReactTCE -- no gamma function ratio, no z vibrational degrees of freedom term, and different exponents on both factors. That is a physics question rather than a port question, so it is reported rather than changed, and shipping a deck that tallies nothing would record the current behaviour as correct.

On a CPU both sides are one allocation, so every one of these is invisible; on a GPU each is silent corruption. 124 decks, the enabled CI suites plus the scratch decks, under poison and under watch/stale. 1. compute_surf_kokkos.cpp / compute_react_surf_kokkos.cpp -- tallyinfo() syncs the host, compresses array_surf_tally and tally2surf in place on the host, and never claims them. The next post_surf_tally() calls modify_device(), which discards the compression: [watch] surf:array_surf_tally: the host side was written, never claimed, and is now lost the write is between sync_host and modify_device element 90 of 250 changed from 0 to -53.0866 The caller consumes the host pointer immediately and clear() rebuilds both sides next step, so the two are deliberately apart from the compression until then. clear_sync_state() is what declares that. 2. surf_react_adsorb_kokkos.cpp -- SurfReactAdsorb::tally_update() rewrites the per-surf custom arrays on the host (surf->edvec_local, surf_react_adsorb.cpp:612-613) and nothing claimed them, so a later SurfKokkos::sync(Device,CUSTOM_MASK) finds clean counters and copies nothing: [watch] surf:dvector: the host side was written without a claim and this sync_device has nothing to copy -- the device keeps stale data The device would run every step after the first on the previous step's surface state. Claimed through the SurfKokkos wrapper rather than the dual view, so the mask reaches the custom arrays. 3. fix_emit_surf_kokkos.cpp -- ~FixEmitSurfKokkos() writes tasks[i] and delete[]s pointers read out of it without owning the host side, which the last modify_device() may have taken. Poison traps all four lines on examples/emit/in.emit.surf.mflow. 4. fix_ave_histo_kokkos.cpp -- a different class, caught by the same pass. FixAveHisto allocates bin with new double[] (fix_ave_histo.cpp:417) and frees it with delete[] (:482), but the Kokkos constructor released it with memory->destroy(), which routes to free(). AddressSanitizer: ERROR: AddressSanitizer: alloc-dealloc-mismatch (operator new [] vs free) Undefined behaviour on any build, not just a GPU one. Two further watch families are reported but not fixed here, because the fix is a design decision rather than a missing declaration: surf/spread:edarray_local_array on the eight examples/custom/in.custom.circle.* decks, and surf:dvector on surf_react_adsorb, both of which persist after 2.

SurfKokkos::modify() was asymmetric with SurfKokkos::sync(). Under CUSTOM_MASK, sync() reads both the owned views and the spread (_local) ones (surf_kokkos.cpp:248, :269), but modify() marked only the owned half. A host write to a spread array therefore could not be claimed through the wrapper at all: the claim marked eivec/eiarray/edvec/edarray, the following sync(Device,CUSTOM_MASK) looked at the *_local views, found clean counters and copied nothing. modify() now marks both halves, for Host and for Device. That was the reason two further claims were needed and did not help on their own: SurfReactAdsorbKokkos::init() -- SurfReactAdsorb::init() fills area, weight and tau through surf->edvec (surf_react_adsorb.cpp:460-461, :531, :551) and spreads them to the local lines/tris (:604-608). A one-time setup write that nothing claimed, so the device began from whatever add_custom() had left. SurfReactAdsorbKokkos::tally_update() -- update_state_surf() re-spreads the state every nsync step (:1560-1561). Together these clear every watch report on the surf_react_adsorb suite: [watch] surf:dvector: the host side was written without a claim and this sync_device has nothing to copy -- the device keeps stale data [watch] surf/spread:edarray_local_array: (same) in.beam.surf.gs, in.beam.surf.ps, in.beam.surf.gs_ps and in.circle.ps go from four reports each to none. The grid_changed() override added here is for the same reason: that path also re-spreads on the host (:1262-1266) with no claim.

A fix does not: the output persists across steps, and the grid migration hooks (pack/unpack/copy/add_grid_one) edit it on the host, leaving the device side holding pre-migration rows. Nothing pushed it back -- FixAveGridKokkos' hooks note that "the device is refreshed lazily in end_of_step()", which is the next step, after every consumer in this one has already read it. Consumers read those rows straight from d_vector_grid / d_array_grid in a kernel, so any deck that adapts or rebalances the grid gets stale per-grid values for the rest of that step. examples/adjust_temp/in.circle.adjust is the reproducer: fix ave/grid, then fix adapt in the same end_of_step, whose candidates_coarsen() invokes compute lambda/grid on the migrated grid. Add KokkosBase::sync_per_grid_device(), a no-op by default and overridden by FixAveGridKokkos to sync its own dual views, and call it at the five sites that read a fix's per-grid device views: compute lambda/grid (both the nrho and the temp operand), compute fft/grid, fix ave/grid, fix ave/histo and fix ave/histo/weight. Found with the split-memory sync debugger in poison mode, which faults on the dereference rather than on the accessor: the stale reporter never flagged these, because the read is of a raw device view the consumer cached, not of the DualView. ASan reported use-after-poison at compute_lambda_grid_kokkos .cpp:213 and :258 on all four adjust_temp decks; all four are clean after.

Giving the host side its own allocation and driving the state machine in software makes those faults reproducible on the CPU. Running the ctest regression suite that way, against a control build with the instrumentation compiled out, turned up the following. Each is described in the order it bites. fix adapt + collide aborted outright. CollideVSSKokkos::sync(Device,mask) declares the host modified when automatic syncing is on, so that writes made through the plain vremax/remain pointers by non-Kokkos code are copied down. It did so unconditionally, and Kokkos aborts a DualView claimed on both sides at once. collisions() claims the device every step and nothing calls the collide sync(Host) in the run loop, so that claim stands for the whole run: a trace of collide:vremax in examples/custom in.custom.spiky.set shows the counter climbing (0,91), (0,92) ... (0,99) before the modify_host at (0,100) that kills it. fix adapt is the caller that gets there, because FixAdaptKokkos sets kokkos_flag = 0 and ModifyKokkos::end_of_step() therefore turns auto_sync on around FixAdapt::end_of_step(), from inside which grow_percell() syncs to the device. Refresh the host before declaring it modified: a no-op when the device is clean, and the copy the host is owed when it is not. ParticleKokkos, GridKokkos and SurfKokkos carry the same three lines and so the same hazard, but nothing in the suite reaches them that way, so they are left alone rather than changed unexercised. fix adapt also fed a compute stale cells. compute lambda/grid, compute dt/grid, compute fft/grid, fix ave/histo, fix ave/histo/weight and fix dt/reset all read another style's per-grid output by taking d_vector_grid or d_array_grid straight out of it and launching a kernel on the handle. With a compute as the source they invoke it first, so its device copy is fresh; with a fix they do not, and fix ave/grid does not keep its device copy fresh -- pack_grid_one(), unpack_grid_one(), copy_grid_one() and add_grid_one() rearrange vector_grid and array_grid on the host as cells migrate and leave the refresh to end_of_step(). AdaptGrid::candidates_coarsen() invokes the value compute after refinement has already migrated cells, so a deck like fix 3 ave/grid all 1 250 250 c_3[*] c_4[*] ave one compute 1b lambda/grid f_3[1] f_3[2] lambda knall fix 10 adapt 250 all refine coarsen value c_1b[2] 2.0 4.5 decides what to coarsen from pre-migration cell values. examples/adjust_temp in.circle.constant and in.sphere.constant and examples/surf_react_heatflux all hit it. Give KokkosBase a sync_pergrid_device_kokkos() hook, have FixAveGridKokkos answer it with pergrid_sync(Device), and call it where a fix's per-grid arrays are read; it costs a virtual call that does nothing for every style that keeps its output on the device already. fix temp/rescale rescaled thermal velocities in a device kernel and returned without claiming particle:particles in datamask_modify or marking it modified. The next step's move() claims the device and hides it, which is why the numbers come out right today. fix grid/check reached past ParticleKokkos::sync() and GridKokkos::sync() and called sync_device() on k_particles, k_cells, k_cinfo and k_sinfo itself -- the only place in the package that does. The wrappers are not a formality: with automatic syncing on they declare the host modified first, which is what carries non-Kokkos host writes down to the device, and GridKokkos::sync() carries the prewrap guard. This fix runs at end_of_step, right after grid adaptation and load balancing have rewritten those arrays on the host, so it is the caller least able to skip that; reading a stale device copy makes a grid checker report particles outside their cells that are not, or miss ones that are. Declare PARTICLE_MASK too, rather than EMPTY_MASK. fix grid/check also accepted the outside keyword and did not honour it. The base class checks, when outside is set, whether a particle in a cell holding surfs is inside them; the Kokkos version cannot, because that test needs grid->point_outside_surfs() and the cut2d/cut3d machinery behind it, and there is no device implementation. It ran the smaller check and said nothing. A grid checker that tests less than it was asked to is worse than one that is not there, so refuse the keyword instead. ComputeSurfKokkos::tallyinfo() and ComputeISurfGridKokkos::tallyinfo() sync tally2surf and array_surf_tally to the host, compress them in place there, and never claim the host for it -- 7481 lost-write reports in one suite run. Within a clear() cycle the dense list is consumed straight away, so ordinary runs are right; what is exposed is the early return once `compressed` is set, which hands back tally2surf and ntally without syncing, so a realloc in between (the init_normflux() that reallocate() runs on every grid or surf change, e.g. fix ablate regenerating implicit surfs) resizes on whichever side the counters call newer -- the device -- and the compressed list is gone before the second caller reads it. Claim the host after the compression, and clear the pair's state in clear() where a new cycle starts and the device copy is about to be zeroed and refilled, so the modify_device() in post_surf_tally() does not meet an outstanding host claim. CommKokkos::migrate_particles() handed the self copy a null view. On the GPU-aware path with no custom attributes, received particles land straight in the particle list past nlocal, and exchange_uniform() is given that address -- but the view argument beside it is d_rbuf, which is only ever allocated in the other branch, so it arrives default constructed, extent 0 and null data. exchange_uniform() copies the self datums itself, into that view. Nothing has noticed because migrate_particles never produces a self datum: a particle is on the migrate list precisely because its new cell belongs to another proc, so the destination list never contains me, and an instrumented run over a heavy adapt/balance deck on four ranks confirms num_self is zero in every call. Every other caller of exchange_uniform passes a view describing the buffer it also passes the address of; make this one do the same. With the same instrumentation that is 240 of 240 calls agreeing after the change and none before it. FixEmitSurfKokkos::~FixEmitSurfKokkos() read and wrote the host side of k_tasks while the emission kernels had it claimed for the device. path and fracarea are plain host allocations no device kernel writes, so the values are the right ones and copying the device side back would be beside the point; say that with clear_sync_state() rather than leaving an unclaimed write and a stale read. Two things that are not coherence faults but read as one. fix emit/face and fix emit/surf synced k_ntargetsp or k_tasks depending on perspecies, when both paths need both; the branch is dead code that looks like a missing sync. And GridKokkos named its per-cell custom arrays "surf:ivector", "surf:iarray", "surf:dvector" and "surf:darray", copied from surf_custom_kokkos.cpp, which uses those same four names for the per-surf arrays -- so a profiler line or a coherence error message naming surf:darray could come from either.

It runs from the grid refinement hooks -- add_grid_one() <- Grid::surf2grid_one() <- AdaptGrid::perform_refine() -- which is outside the per-step collide sync discipline, so the collision kernels' in-place vremax updates are still only on the device and have not been pulled back. The modify_host() therefore marks the host dirty over a device that holds unsynced writes, and the sync_device() immediately after copies the stale host values down, discarding them. Sync the two dual views directly instead, which keeps whichever side is actually newer and lets the resize preserve it; the modified(Device,ALL_MASK) already at the end of the function then refreshes the host for the caller. examples/custom/in.custom.spiky.set is the reproducer. Under the split-memory sync debugger it aborted with "concurrent modification of host and device views in DualView collide:vremax" at step ~250, with 100 unsynced device updates pending; gdb put it at grow_percell -> sync(Device) -> modified(Host) -> modify_host. The deck now runs its full 1000 steps clean.

Binding the Kokkos reducer to that member does not accumulate, though: the result pointer handed to parallel_reduce is passed straight to reducer.init() before the kernel runs (Kokkos_Serial_Parallel_Range.hpp, where ptr is m_result_ptr when a result is bound), so every launch overwrote the member with the MinMax identity. Only the last binning kernel's extrema survived -- across the repeat window, across multiple input values in one call, and over any host-side bin_one() result that a later device launch wiped. The Min and Max columns therefore diverged from a non-Kokkos run. Reduce into a scratch value and fold it in instead: minmax_reset() before a helper's launches and minmax_fold() after. The launches inside each bin_* helper are mutually exclusive branches, so one reset/fold pair per helper covers them all, including the case where no branch runs (folding the identity is a no-op). fix ave/histo appears in no enabled test suite, so ctest does not cover this; verified by hand against the host.

MAXSMALLINT is INT_MAX and nnew is an int, so that comparison is false for every possible value -- the guard could never fire. The scan itself wraps to a negative nnew first, which then flows into nlocal and into grow(nnew - nlocal_save) rather than erroring out. offset_scan() (kokkos_scan.cpp) already solves exactly this: it accumulates in bigint and aborts with a clear message when the total exceeds 2^31, and it is what create_particles and the emit fixes already use. Use it here too, which also drops the hand-rolled mirror/deep_copy of the scan's last element.

Its surf_collide index maps derive only from surf->sc[n]->style, which is fixed for a run -- surf_collide is a between-runs command -- yet each iteration allocated two fresh host mirrors via create_mirror_view and pushed both maps to the device. Build them once per run, keeping nsc_style[] and the mirrors; init() invalidates so a new run rebuilds. The model blit and upload_surf_collide_models() still repeat, since pre_collide() does refresh d_particles. The four per-event tally computes published their rows with a full sync_host() of a maxtally-sized dual view, a host destroy/create, and an element-wise double loop -- every step. maxtally is a high-water mark while ntally is the step's event count, and the host half of the dual view has no other reader. Copy the live rows straight into array_tally with one deep_copy through an unmanaged LayoutRight wrap (Memory::create hands back a contiguous row-major block with the same nvalue stride), and keep array_tally on its own high-water mark. Same shape as the fix field/{grid,particle} fix. fix ave/grid/kk moved the whole nglocal x ntotal tally to the host and back for every host-side value inside its value loop, so three grid variables cost six full transfers where two do. Track which side is current and transfer only at a crossing; device values (computes, fixes publishing a device view, custom attributes) claim the device first, so an interleaved sequence stays correct. The three emit fixes re-flattened their region to a device token stream in perform_task(), i.e. every step, rebuilding it on the host and re-uploading. A region is fixed for a run -- Region exposes no move or rotate and "region" is an input command -- so flatten once from init(). No behavior change intended. ctest is unchanged at 36/246 with the failure set identical in both directions. Not measured: this machine has no GPU, and on a host backend a dual view's two sides are the same allocation, so none of these transfers cost anything here.

The eflux/pflux/sonine columns added here for coverage are "reduce ave" over per-cell fluxes that fluctuate in sign, so once trajectories diverge at all they differ by order unity -- and at mpi_4 the reduction order can vary between runs, so even a CI-blessed log would be flaky. Those columns cannot carry a cross-machine gold comparison in this deck. master ships no gold logs for either suite, so removing these restores that: the harness blesses on the fly and the decks still run every CI job, which keeps what the added computes were for -- eflux/grid, pflux/grid, sonine/grid and ke/particle are exercised where before they appeared in no enabled deck at all. What is lost is value comparison, which these columns could never have provided across machines. The in.relax_const stats additions stay.

Separate logs per descriptor: mpi_1 and mpi_4 are not interchangeable, since create_local_twopass() seeds the particle-creation RNG per rank (create_particles.cpp:843), so the two rank counts produce different -- both correct -- realizations. One log per descriptor is enough for all three CI jobs. The mpi-stubs build at one process and the real-MPI build at one rank produced identical output on the runner, and twopass makes the Kokkos build match the host: locally, host and -sf kk agree to every digit at both 1 and 4 ranks. Why the previous logs failed, now measured rather than guessed. Comparing a local run against the CI run of the same commit: steps 0-133 bit-identical step 134 first divergence, last printed digit of c_EF[1] (~4e-8) step 184-199 order-unity differences on the fluctuating columns Natt 11 Ncoll 835 c_Ttrans 6.5565 c_Trot 9.8479 c_EF[1] 575640 c_EF[2] 337478 c_PF[1] 120.963 c_PF[2] 118.249 c_SN[1] 3.51e7 c_SN[2] 6.75e10 c_KE 2.99e-19 which reproduces the CI diff exactly. Particle creation is identical across machines; the divergence starts in the collision loop, where a last-ulp difference flips an accept/reject in the rejection sampler and shifts the RNG stream from that point on. Everything downstream then decorrelates. Against the harness's 1e-7 absolute tolerance no column survives that, which is why relax_variable failed too despite carrying none of the diagnostics added here. c_EF, c_PF[2] and c_SN are zero-mean fluctuating moments -- across three seeds at step 0 they change sign and vary by their own full magnitude -- so they assert little beyond "the computes ran and produced finite numbers". c_Ttrans, c_Trot, c_PF[1] and c_KE are the columns with real diagnostic value. All are kept: eflux/grid, pflux/grid, sonine/grid and ke/particle appeared in no enabled deck before this branch. These logs will not reproduce on a machine whose libm shifts the RNG order, which is already true of roughly three dozen decks in the suite.
