From f52e2099ceb8f530c3517ddff106f90fc58f3bb5 Mon Sep 17 00:00:00 2001 From: Igor Lins e Silva <4753812+igorls@users.noreply.github.com> Date: Mon, 24 Aug 2026 22:25:47 -0300 Subject: [PATCH 01/45] fix(ops): size persistent grids from the active device's SM count MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit GDN chunked output and sparse-MoE prefill sized their persistent grids from a hardcoded RTX 5090 constant (170 SMs). Query the multiprocessor count of the active device once and cache it, so any sm_120a part gets one full resident wave: wider dies (RTX PRO 6000 Blackwell, 188 SMs) no longer leave SMs idle and narrower parts are no longer oversubscribed. Measured performance-neutral on an RTX PRO 6000 for the Qwen3.8-27B NVFP4 target (57.6k-token prefill: 6321 stock vs 6232 patched tok/s, within run-to-run noise) — these kernels are not that target's prefill bottleneck. The change is portability correctness, not a speedup. The device query falls back to the 170-SM reference value if it fails. --- src/CMakeLists.txt | 1 + src/ops/common/device_info.cu | 30 +++++++++++++++++++ src/ops/common/device_info.h | 18 +++++++++++ .../gated_delta_net/chunked/output.cu | 12 ++++---- .../prefill/sparse_moe_prefill_kernels.cu | 21 +++++++------ 5 files changed, 67 insertions(+), 15 deletions(-) create mode 100644 src/ops/common/device_info.cu create mode 100644 src/ops/common/device_info.h diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt index f5590f3f77..7ea29fe9bd 100644 --- a/src/CMakeLists.txt +++ b/src/CMakeLists.txt @@ -61,6 +61,7 @@ target_link_libraries(ninfer_nvfp4_tma PRIVATE ninfer_core CUDA::cudart CUDA::cu # Shared mathematical Ops.

This adds a PrefixSeedStore: an immutable, content-addressed store of complete sequence-state snapshots (Linear Attention conv+recurrent images, Text and MTP KV page payloads, tail hidden, host ledger and prefix identity) captured at the rendered system block's token frontier during an ordinary prefill, and restored by copy into a fresh lane for any later request whose prompt begins with the identical tokens. Capture rides the existing in-graph rewrite-checkpoint mechanism: the chunk containing the seed frontier passes it as that chunk's capture frontier, and the executor exports the lane checkpoint slot into the store after the chunk completes. When the request's own rewrite capture falls in the same chunk at a different frontier, the chunk is split at the seed frontier so both captures get their own chunk (a large stable head plus a short live turn makes that collision the common shape). Restore is copy-only, so concurrent requests can all seed from one entry; nothing is claimed or consumed, and the store holds no KV-pool pages, leaving admission accounting unchanged. The store is a startup-fixed device arena behind --prefix-cache-mib (EngineOptions::prefix_cache_bytes; default 0 = off), evicting wholesale when full. Requests log the new reuse path as reuse=seed_prefix. Measured on an RTX PRO 6000 (Qwen3.8-27B NVFP4, MTP-5, int8 KV, 10.5k-token system head, greedy): sibling requests drop from ~1120ms TTFT (full_reset) to 57-63ms (seed_prefix, cache=10487), parallel siblings both hit the same entry, and a seeded request's output is bit-identical to its cold twin. v1 scope: text-only prompts, single seed frontier (end of the rendered system block), MTP and no-spec backends (DFlash excluded), no persistence across restarts. Lane selection does not yet prefer a longer resident continuation over a shorter seed when both match; the seeded plan can win with a marginally smaller reuse base. --- include/ninfer/types.h | 3 + src/serve/generation_service.cpp | 1 + src/serve/request_log.cpp | 2 + src/serve/serve_options.cpp | 11 +- src/serve/serve_options.h | 1 + src/targets/qwen3_6/CMakeLists.txt | 1 + .../ninfer/targets/qwen3_6/prepared_prompt.h | 3 + .../qwen3_6/impl/frontend/chat_template.cpp | 6 +- .../qwen3_6/impl/frontend/chat_template.h | 2 + .../qwen3_6/impl/frontend/frontend.cpp | 5 +- .../qwen3_6/impl/frontend/processor.cpp | 25 ++ src/targets/qwen3_6/impl/frontend/processor.h | 1 + src/targets/qwen3_6/impl/runtime/layouts.h | 2 + .../qwen3_6/impl/runtime/layouts_impl.h | 2 + .../impl/runtime/prefix_seed_store.cpp | 290 ++++++++++++++++++ .../qwen3_6/impl/runtime/prefix_seed_store.h | 130 ++++++++ src/targets/qwen3_6/impl/runtime/program.h | 8 + .../qwen3_6/impl/runtime/program_impl.h | 90 +++++- .../qwen3_6/impl/runtime/request_plan_impl.h | 51 ++- 19 files changed, 624 insertions(+), 10 deletions(-) create mode 100644 src/targets/qwen3_6/impl/runtime/prefix_seed_store.cpp create mode 100644 src/targets/qwen3_6/impl/runtime/prefix_seed_store.h diff --git a/include/ninfer/types.h b/include/ninfer/types.h index c074a3e04a..55316d9ee7 100644 --- a/include/ninfer/types.h +++ b/include/ninfer/types.h @@ -89,6 +89,8 @@ struct EngineOptions { std::uint32_t media_preprocess_threads = 0;

Platform code: - artifact/reader.cpp: MappedFile Windows branch (CreateFileW/MapViewOfFile/SetFilePointerEx+ReadFile); fix LARGE_INTEGER aggregate-init truncating file offsets >= 4 GiB (must set .QuadPart) - request_log.cpp: getpid -> GetCurrentProcessId; load_progress.cpp: isatty -> GetConsoleMode; acquire.cpp: Winsock branch - CMake: NINFER_BUILD_MEDIA option (OFF on Windows) + decode/acquire stubs; MSVC C++20 friction fixes NVFP4 TMA fix (Windows-only crash at T>=1024 prefill): MSVC cannot pass the 128-aligned CUtensorMap by value (C2719), so the kernels take a pointer. The TMA unit reads tensor maps through a separate tensormap proxy: kernel-side (generic-proxy) writes to a descriptor staged in local memory are invisible to it without fence.proxy.tensormap, which surfaced as 'Illegal instruction' at the first cp.async.bulk.tensor. Both TMA kernels now read the descriptor directly from the host-written global buffer (cudaMalloc'd, 256-byte-aligned, cudaMemcpyAsync H2D) - no in-kernel staging, no fence.

Parameters typed as `"string"` +(or declared via a type array that includes `"string"`), parameters with an unknown or misspelled +`"type"`, and parameters absent from the schema preserve the model's raw text so the string +contract reaches the client intact. Full JSON Schema validation (constraints, required sets, +formats, nested keywords) is not performed server-side and remains the client's job. +Duplicate tool names within a single request are rejected with a 400 on all three +protocol surfaces (OpenAI Chat Completions, OpenAI Responses, Anthropic Messages), +keeping the per-tool parameter type map unambiguous. Prompt-token usage includes chat-template and expanded media tokens. Generated-token usage comes from accepted output token IDs, including a stop token whose decoded text may be withheld. diff --git a/src/serve/anthropic_schema.cpp b/src/serve/anthropic_schema.cpp index ba3c6e26b6..763e2e10c6 100644 --- a/src/serve/anthropic_schema.cpp +++ b/src/serve/anthropic_schema.cpp @@ -8,6 +8,7 @@ #include #include #include +#include #include namespace ninfer::serve { @@ -141,6 +142,7 @@ void parse_tools(const Json& body, GenerationRequest& out) { const Json& tools = body.at("tools"); if (!tools.is_array()) { bad_request("tools must be an array", "tools"); } out.tools.reserve(tools.size()); + std::unordered_set names; for (const Json& item : tools) { if (!item.is_object()) { bad_request("tools entries must be objects", "tools"); } // Anthropic server/built-in tools carry a `type` and no `input_schema`; we @@ -155,6 +157,9 @@ void parse_tools(const Json& body, GenerationRequest& out) { } ToolDefinition tool; tool.name = require_function_name(item, "tools"); + if (!names.insert(tool.name).second) { + bad_request("duplicate tool name: " + tool.name, "tools"); + } Json function = Json{{"name", tool.name}}; if (item.contains("description") && !item.at("description").is_null()) { if (!item.at("description").is_string()) { diff --git a/src/serve/generation_service.cpp b/src/serve/generation_service.cpp index 8ec5791609..05c70f2418 100644 --- a/src/serve/generation_service.cpp +++ b/src/serve/generation_service.cpp @@ -280,6 +280,7 @@ PreparedRequest GenerationService::prepare( prepared.include_usage = request.include_usage; prepared.tool_capable = request.uses_tools() || request.has_tool_history(); prepared.tool_name_max_length = request.tool_name_max_length; + prepared.param_types = build_tool_param_type_map(request.tools); const ResolvedPromptSemantics semantics = resolve_prompt_semantics(request, options_, prompt_capabilities_); prepared.enable_thinking = semantics.enable_thinking; @@ -407,9 +408,9 @@ GenerationOutcome GenerationService::run(PreparedRequest& prepared, const Stream bool is_tool_call_response = false; if (prepared.tool_capable) { - ParsedToolCallOutput parsed = - parse_qwen_tool_call_output(outcome.text, prepared.tool_name_max_length, - options_.tolerant_tool_calls); + ParsedToolCallOutput parsed = parse_qwen_tool_call_output( + outcome.text, prepared.tool_name_max_length, prepared.param_types, + options_.tolerant_tool_calls); outcome.text = std::move(parsed.content); is_tool_call_response = parsed.is_tool_call_response; if (is_tool_call_response) { @@ -418,8 +419,8 @@ GenerationOutcome GenerationService::run(PreparedRequest& prepared, const Stream // A Qwen drift can emit the call before .

ToolCallStreamFilter only withholds the prefix when the whole marker lands in one chunk; with token-by-token streaming the marker straddles chunks, the prefix is already on the wire, and unstreamed_content then throws "streamed content exceeds terminal content" -- aborting the request mid-stream with a 500 on exactly the turn the suppression was meant to clean up. The parser now retains the prefix. GenerationService clears it only when streamed_content_bytes == 0, so a non-streaming tool turn still shows no chatter while a streamed one stays consistent. Regression test asserts terminal content is never shorter than emitted bytes, for both the split-marker and whole-marker cases.

charset=UTF-8 Content-Transfer-Encoding: 8bit Issue #10 made /health answer 503 once the inference executor has failed, which stopped the process from claiming health it did not have. But a 503 nothing polls is not actionable: the container still runs, still holds its VRAM, and still answers every inference request with an error. /health is the only unauthenticated endpoint, so the probe needs no API key. Two things this deliberately does not pretend to do: - It does not recover anything. Docker restart policies act on process EXIT, not on health status, so `--restart unless-stopped` will not restart an unhealthy container. This makes the failed state visible to `docker ps`, to monitoring, and to a watcher; recovery still needs Swarm, an external monitor, or the native supervisor's health-restart path. Process exit on permanent executor failure remains the outstanding half of #10. - It does not follow --port. HEALTHCHECK is static, so the probe reads NINFER_PORT (default 8080, matching EXPOSE and the ServeOptions default) and operators must set it to match --port. start-period is 180s because the server binds before loading the model and only listens afterwards: the probe sees connection-refused for the whole load, which is ~35s for Qwen3.8-27B NVFP4 here but scales with the artifact. curl is added to the runtime stage — it shipped libcurl4t64 (the library) but no HTTP client. Verified: `docker build --check` clean; `curl -fsS /health` exits 0 against the live lane; `curl -f` exits 22 on an error status, so a 503 marks the container unhealthy rather than passing. Note the production lane does not use this image — it runs the CUDA devel base with a mounted build tree — so no running container changes here.

SECURITY (the addendum, and it corrects my own earlier review). A loopback peer-address check is not authorization when the browser is the confused deputy, because the browser is itself on loopback. Any page could POST to /api/stop with no preflight and kill the engine; nothing validated Host, so a rebound attacker domain could also read /api/state and /api/events. - Host allowlist on EVERY route via a pre-routing handler: loopback names plus the configured host when --bind-any names a specific interface. Binding 0.0.0.0 does not open the allowlist. - Mutating routes additionally require X-NInfer-Supervisor: 1. This works only because the server sends no CORS headers, so the preflight that a custom header forces goes unanswered and the request is never sent. That absence is load-bearing, not incidental. - Order is peer check, then header check, then the monitor-only 409. The 409 is layered on top and is not a substitute: managed mode is default. Matching is exact, never substring or prefix. Added tests for the trap that reintroduces this as a bug — localhost.evil.com, 127.0.0.1.evil.com, evil-localhost, and a prefix of the --bind-any host all reject. VRAM LABELS. The card previously showed DXGI CurrentUsage as "this process", which is the supervisor's own footprint (~0, it makes no CUDA allocations) and never the engine's. QueryVideoMemoryInfo reports the calling process, so this stays wrong even for a spawned child, and our production engine is a WSL2 container in a different process tree. Budget is now labelled as the system-wide WDDM pressure signal it actually is, device used/total comes from nvidia-smi, and the per-process row says plainly it is not the engine. MONITOR-ONLY. The supervisor could only observe an engine it spawned, which excluded the containerised production lane. --monitor-only (or an unmanaged engine entry) observes without spawning or restarting: DXGI budget and nvidia-smi from its own process, /health for liveness, bearer auth for the rest. Control routes return 409. Tests pass under Linux/g++ as well as MSVC; the logic header stays portable.

Now it draws a rounded "N" tile whose fill colour is the engine's status: green running, amber starting/stopping/backing-off/unreachable, red halted or crash-looped or reporting unhealthy, grey idle. A 1 Hz timer repaints only on change, and the tooltip names the status in words. Drawn at runtime rather than shipped as an .ico resource: no build-system change, no binary asset in the tree, and it renders at whatever size SM_CXSMICON reports instead of being pinned to one raster. Two details that are easy to get wrong and were worth pinning down: - The colour bitmap is an explicit 24bpp DIB section, NOT CreateCompatibleBitmap. A screen-compatible DDB is 32bpp on any modern display, and CreateIconIndirect then reads its alpha channel as per-pixel alpha. GDI never writes alpha, so every pixel comes out fully transparent and the icon silently vanishes. At 24bpp there is no alpha to misread and the 1bpp mask alone decides the shape. - The colour fill is full-bleed and the rounded corners are cut by the mask, so the glyph antialiases against its own fill instead of fringing against a background colour. In monitor-only mode the colour still reflects OBSERVED health rather than a neutral "not my process": EngineChild maintains st_.health for unmanaged engines via observe_health(), so this is measured, not invented. The managed/observing distinction goes in the tooltip, where it can be stated in words instead of being guessed from a hue. Status is read from EngineChild's in-memory status — never Collector::snapshot(), which spawns nvidia-smi and makes two HTTP calls and has no business on a 1 Hz UI timer. gdi32 added to the link libraries; the GDI calls this needs were not covered by the existing list.

The engine writes {"event":"request_done"}. There is no "type" field, so the lookup returned "" for every record and each one hit `continue`. The two checks disagreed about the key name, and only the second one was load-bearing. Nothing else was wrong: result.completion_tokens, result.prefix_reuse_path, timings_seconds.ttft and timings_seconds.decode all match the schema (v10). Against live production traffic this now reads done=12, decode 167.1 tok/s, TTFT 231.8 ms, reuse mix full_reset 5 / seed 5 / append 2 — where it read zeroes before. Also points the monitor-only example at the host-visible log path. The production container now bind-mounts P:/NInfer/supervisor-logs to /logs and writes its JSONL there, because /tmp/prod.jsonl lived inside the container where a native Windows supervisor has no path to it. That also fills in the boot capacity line, which is parsed from the same file's server_start record.

THE SERIES. A 6000-sample ring (10 minutes at 10 Hz) rendered as an inline SVG polyline — no chart library, the page stays offline and CSP-tight. DXGI Budget and nvidia-smi device-used share one time axis, and engine up/down and /admin/vram actions are drawn as event markers so a budget collapse can be read against the action that caused it. Deliberately unsmoothed, and labelled as such in the UI: the oscillation is the finding, and an average erases exactly the artifact issue #7 exists to characterise. THE FIX. series_loop() called poll_nvidia_smi() on every tick. That is a PROCESS SPAWN, measured at ~51 ms on this box, against a 100 ms period. measured before: ~9.3 spawns/s, ~48% of one core in spawns, 5% supervisor measured after: ~1.0 spawns/s, ~5% of one core in spawns, 2% supervisor The waste is the smaller half. The real problem is that this instrument is meant to observe a machine under a game-test workload, and a monitor burning half a core and issuing driver queries ten times a second is competing with the very thing it is measuring. A perturbing instrument reports its own interference. DXGI is an in-process call and stays at the full rate, because the budget oscillation must not be decimated. Device totals move slowly, so they are polled at 1 Hz and the last reading is carried forward into the fast series. Verified live: 253 samples over 27.4 s, 9 distinct nvidia readings across that span, event markers present.
