## Overview
-RoboCache is a high-performance CUDA library for real-time sensor preprocessing in robotics. Eliminates CPU dataloader bottlenecks with **GPU-accelerated temporal alignment** and **point cloud voxelization**.
+RoboCache is a CUDA library for sensor preprocessing in robotics: GPU-accelerated
+temporal alignment (trajectory resampling, multimodal fusion) and point cloud
+voxelization, with a pure-PyTorch fallback.
-**Key Features:**
-- 🚀 **Sub-millisecond latency** - 0.021-0.035ms on H100 (measured)
-- ⚡ **GPU-accelerated with BF16** - CUDA kernels with vectorized loads
-- 🎯 **Production-ready** - A100/H100 validated, ROS 2 integration
-- 🔧 **Battle-tested** - 24h burn-in, Compute Sanitizer verified
+**Scope of validation:**
+- CUDA kernels were benchmarked on H100 PCIe and A100 SXM4 in November 2025.
+- All benchmark inputs were synthetic tensors (`torch.randn` / `torch.rand`),
+ including the "dataset" benchmarks, which use tensors shaped like Isaac Gym,
+ TartanAir, nuScenes, and KITTI samples - no real dataset files were loaded.
+- The CPU fallback has known correctness bugs (see [Known Issues](#known-issues)).

+## Known Issues
+
+- **CPU voxelization fallback is incorrect.** `ops_fallback.voxelize_pointcloud_cpu`
+ clamps out-of-bounds points into boundary voxels instead of dropping them
+ (diverging from the CUDA kernel), and raises `IndexError` on empty or
+ single-point clouds. The corresponding CPU tests are marked `xfail`. Do not
+ use the CPU fallback where voxel occupancy correctness matters.
+- **Stale multimodal-fusion tests.** `robocache/tests/test_multimodal_fusion.py`
+ targets a pre-1.0 two-stream `fuse_multimodal` API and is skipped; the current
+ API takes three streams.
+- **Compute Sanitizer / 24h burn-in were never run in CI.** The stress-test code
+ exists but there is no committed memcheck/racecheck log.
+- **Voxelization out-of-bounds behavior (CUDA):** points outside the grid are
+ clipped, no error is thrown.
+- **Timestamp monotonicity is not enforced;** callers must supply monotonically
+ increasing timestamps.

-## Known Limitations
-
-### Performance Considerations
-- **Trajectory Resampling:** Optimal for batch sizes 8-64. Single-sample latency may be dominated by kernel launch overhead (~5μs).
-- **Voxelization:** Throughput scales with point count. For <10K points, CPU implementation may be competitive due to launch overhead.
-- **Multimodal Fusion:** Currently uses 3 sequential kernel launches. Kernel fusion could reduce latency by ~40% (future optimization).
-
-### Hardware Compatibility
-- **Minimum:** CUDA Compute Capability 8.0 (A100, A10G, RTX 3090)
-- **Tested:** H100 PCIe (SM90), A100 SXM4 (SM80)
-- **Not tested:** V100 (SM70), consumer GPUs (RTX 4090)
-- **BFloat16:** Requires SM80+ (A100/H100). Falls back to FP32 on older hardware.
-
-### API Stability
-- **Public API:** `resample_trajectories()`, `voxelize_pointcloud()`, `fuse_multimodal()` - stable
-- **Experimental:** Streaming kernels, CUTLASS-based implementations - subject to change
-- **Backward compatibility:** See `artifacts/kernel_inventory.md` for production vs research status
-
-### Functional Limitations
-- **Timestamp monotonicity:** Not enforced. User must ensure monotonically increasing timestamps.
-- **Out-of-bounds:** Voxelization clips points outside grid bounds (no error thrown).
-- **Empty inputs:** Zero-length tensors may cause undefined behavior (add validation in production code).
-
-### Documentation
-- **Performance claims:** All claims based on H100/A100 measurements. See `artifacts/h100_validation_final_results.md` for exact configs.
-- **Benchmark reproducibility:** Requires same hardware, driver version, and CUDA toolkit. Variations up to ±10% are normal.

-## Completed P0 Fixes (3/6 actionable)
-
-### ✅ codex-1: CPU Fallback Function Missing
-
-**Codex Concern:** `benchmark_fallback()` calls nonexistent `resample_trajectories_cpu`
-
-**Fix:** Added alias function delegating to `fuse_multimodal_cpu`
-
-**Evidence:**
-- **Commit:** `27e06d2`
-- **File:** `robocache/python/robocache/ops_fallback.py` lines 36-56
-- **Test:** Function is importable and works
-
-**Status:** ✅ COMPLETE

-### ✅ codex-2: Tests Ignore Timestamps
-
-**Codex Concern:** Tests use `torch.nn.functional.interpolate` (index-based), ignore timestamp tensors entirely
-
-**Fix:** Created `test_timestamp_alignment.py` with 6 timestamp-aware tests
-
-**Evidence:**
-- **Commit:** `4759c28`
-- **File:** `robocache/tests/test_timestamp_alignment.py` (329 lines)
-- **Tests:**
- 1. Non-uniform timestamps (clustered grids)
- 2. Phase-shifted timestamps (streams start at different times)
- 3. Jittered timestamps (simulates sensor noise)
- 4. Skewed sampling rates (10Hz vs 500Hz)
- 5. Extrapolation clamping
- 6. Reference implementation using `searchsorted` + lerp (timestamp-aware)
-
-**Status:** ✅ COMPLETE
-

-**Fix:** Added CUTLASS extension to `setup.py`, created PyBind11 bindings
-
-**Evidence:**
-- **Commit:** `32c8054`
-- **Files:**
- - `robocache/setup.py` lines 69-87: CUDAExtension definition
- - `robocache/csrc/cpp/cutlass_ops.cpp`: 70 lines of bindings
- - Links: `kernels/cutlass/trajectory_resample_production.cu` (H100-validated)
-- **Build output:** "Building 4 CUDA extensions (including CUTLASS)"
-- **Module:** `robocache._cutlass_ops`
-
-**Code Quality:** Production-ready
-- Follows PyTorch CUDAExtension API
-- Proper include paths
-- SM80/SM90 compile targets
-- Clean PyBind11 bindings
-
-**Status:** ✅ INFRASTRUCTURE COMPLETE
-
-**Validation Status:** ⚠️ BLOCKED by H100 disk full (97GB/97GB used)
-- Cannot build wheel on H100
-- Cannot install to test imports
-- Cannot run benchmarks

-## Blocked P0 Items (Infrastructure, Not Code)
-
-### ⚠️ codex-6-14: H100 Validation Tasks
-
-**Blocker:** H100 root filesystem 100% full
-
-**Details:**
-```
-Filesystem Size Used Avail Use% Mounted on
-/dev/vda1 97G 96G 781M 100% /
-```
-- 43GB in /var (CUDA drivers, system)
-- 22GB in /usr
-- Cannot: git fetch, build wheel, pip install, run benchmarks
-
-**Impact:**
-- Cannot prove wheel contains `.so` files
-- Cannot test CUTLASS imports after install
-- Cannot benchmark CUTLASS vs reference
-- Cannot NCU profile shipped kernels
-
-**Documented:** `artifacts/h100_infrastructure_blocker.md`
-
-**Alternative Paths:**
-1. Use A100 instance (if it has disk space)
-2. Fix H100 disk space (ops team)
-3. Build locally with NVIDIA GPU
-
----
-
-## Pending P0 Items (Can Complete Now)
-
-### codex-9, codex-10: README Audit
-
-**Codex Concern:** Unsubstantiated performance claims
-
-**What's Needed:**
-- Link every claim to benchmark result
-- Remove unsupported claims
-- Document what ships vs what doesn't
-
-**Status:** Can complete without GPU (documentation task)
-
-**Estimate:** 1-2 hours
-
----

-
----
-
-## Unique Strengths
-
-### 1. Evidence Artifacts (Beyond Industry Standard)
-- `artifacts/h100_validation_final_results.md`
-- `artifacts/performance_claims_evidence_matrix.md`
-- `artifacts/readme_audit_findings.md`
-- `artifacts/cutlass_h100_validation.md`
-
-**Rationale:** Most projects don't maintain this level of evidence tracking. This is closer to internal NVIDIA validation than typical open-source.
-
-### 2. Timestamp-Aware Testing (Uncommon)
-- Non-uniform timestamp tests
-- Phase-shifted timestamp tests
-- Jittered timestamp tests
-
-**Rationale:** Most multimodal fusion tests use index-based interpolation. RoboCache tests actual timestamp alignment.
-
-### 3. Comprehensive CI (Above Average)
-- Weekly performance regression checks
-- Kernel build validation
-- Compute Sanitizer integration
-- Dual GPU validation (H100 + A100)
-
-**Rationale:** Many projects have basic CI. RoboCache has production-grade validation.
-
----
-
-## Areas of Parity (Not Better, But Equal)
-
-### 1. Kernel Performance
-- RoboCache: 0.034ms multimodal fusion
-- Flash Attention 3: 0.05-0.1ms attention (similar scale)
-
-**Rationale:** Both achieve sub-millisecond latency for their respective operations.
-
-### 2. Mixed Precision
-- RoboCache: FP32/FP16/BF16 with CUDA intrinsics
-- Triton: FP32/FP16/BF16 with compiler support
-
-**Rationale:** Both handle mixed precision correctly, different implementation methods.
-
-### 3. Build System
-- RoboCache: PyTorch CUDAExtension
-- PyTorch: PyTorch CUDAExtension (same)
-
-**Rationale:** Using the same toolchain, no advantage either way.
-
----
-
-## Final Verdict
-
-### Overall Comparison
-
-| Standard | Assessment |
-|----------|------------|
-| **vs PyTorch** | ✅ **MEETS** - Same build system, comparable quality |
-| **vs Triton** | ✅ **MEETS** - Similar testing rigor, mixed precision |
-| **vs Flash Attention 3** | ✅ **MEETS/EXCEEDS** - Similar profiling depth, more evidence artifacts |
-
-### Excellence Confirmation

-
-## EXPERT OPINION
-
-**As a 15+ year CUDA engineer:**
-
-This codebase is **solid**. The external review was **overly harsh** - 50% of their claims were false positives (API naming mismatch, atomic float bug that doesn't exist).
-
-The two real issues I found:
-1. Dead code file with undefined variables (not in build, no impact)
-2. Documentation overclaimed "vectorized" (still fast, just iterates batches)
-
-Both are **trivial** and now **fixed**.
-
-The code:
-- ✅ **Builds cleanly**
-- ✅ **Runs correctly**
-- ✅ **Performs as claimed** (H100 measurements verify all claims)
-- ✅ **Uses proper CUDA patterns** (CAS loops, cooperative groups, BF16)
-
-**Recommendation:** This is **production-ready** GPU-accelerated robotics code. Ship it.
-
-**Confidence:** 100%
-**Status:** ✅ AUDIT COMPLETE

-## Roofline Analysis
-
-### H100 Voxelization Kernel
-
-**Measured Performance:**
-- Compute: 7.10% of SM peak
-- Memory: 51.82% of peak bandwidth
-- **Classification:** Memory-bound (as expected for scatter/atomic operations)
-
-**Roofline Position:**
-- Below memory bandwidth ceiling (51.82% < 100%)
-- Well below compute ceiling (7.10% << 51.82%)
-- **Bottleneck:** Memory bandwidth + atomic serialization
-
-**Optimization Assessment:**
-- **Near-optimal** for this algorithm (atomic scatter to irregular grid)
-- 78.62% occupancy is excellent given atomic contention
-- Further optimization would require algorithmic change (e.g., binning, sorting)
-
-**Evidence:** `artifacts/h100/H100_NCU_NSIGHT_REPORT.md` Section 2.1
-
----
-
-### H100 Trajectory Resampling Kernel

-- **Bottleneck:** Uncoalesced memory access from binary search pattern
-
-**Optimization Opportunity:**
-- Streaming/scan-based algorithm available (`trajectory_resample_streaming.cu`)
-- Could achieve 22x improvement (from 1.59% to estimated 35%+)
-- Current kernel: Prioritizes latency over bandwidth utilization
-
-**Evidence:** `artifacts/h100/H100_NCU_NSIGHT_REPORT.md` Section 2.2

-
-**Assessment:** ✅ **All operations have 1,000x+ safety margin**
-
----
-
-### Foundation Model Training
-
-**Typical throughput requirements:**
-- Point clouds: 1-10 Gpts/sec for training dataloaders
-- Trajectories: 1-10 Msamples/sec for episode buffers
-
-| Operation | Platform | Throughput | Requirement | Excess |

-
-**Assessment:** ✅ **All operations exceed training requirements by 10x+**
-
----
-
-## Known Limitations (Documented)
-
-### 1. A100 NCU Profiling Restricted
-
-**Issue:** Cloud A100 instance prevents NCU performance counter access
-
-**Impact:** No kernel-level occupancy/bandwidth metrics for A100
-
-**Mitigation:**
-1. ✅ Comprehensive functional validation (100 iter, statistical analysis)
-2. ✅ Cross-validation with H100 NCU (same kernel source)
-3. ✅ Previous validation on A100 with NCU access (documented in repo history)
-
-**Production Impact:** None. Functional validation proves production readiness.
-
-**Evidence:** `artifacts/a100/A100_VALIDATION_REPORT.md` Section 5.1
-
----
-
-### 2. Binary Search Memory Access Pattern
-
-**Issue:** Trajectory resampling uses binary search → uncoalesced memory access
-
-**Impact:** 14.85% memory bandwidth utilization (H100) - underutilized
-
-**Mitigation:**
-1. ✅ Streaming algorithm available (`trajectory_resample_streaming.cu`)
-2. ✅ Current algorithm prioritizes low latency (29.03μs) over bandwidth
-3. ✅ For bandwidth-critical workloads, switch to streaming variant
-
-**Production Impact:** None. Current latency exceeds requirements by 1,000x+.
-
-**Evidence:** `artifacts/h100/H100_NCU_NSIGHT_REPORT.md` Section 2.2
-

-# Safety-Critical CUDA Audit - Robotics Deployment
-
-**Date:** 2025-11-09
-**Auditor:** Expert CUDA/NVIDIA Engineer (15+ years, safety-critical systems)
-**Focus:** Memory safety, bounds checking, error propagation for robotics
-
----
-
-## EXECUTIVE SUMMARY
-
-**Safety Rating:** ✅ PRODUCTION-READY
-**Critical Issues:** 0
-**Recommendations:** 3 hardening improvements
-
----
-
-## AUDIT SCOPE
-
-### Safety-Critical Areas for Robotics
-1. **Memory Safety:** Bounds checking, buffer overflows, use-after-free
-2. **Error Propagation:** CUDA errors must not be silently ignored
-3. **Determinism:** Same input → same output (critical for testing)
-4. **Race Conditions:** Thread safety in multi-stream scenarios
-5. **Resource Limits:** OOM handling, graceful degradation
-
----
-
-## FINDINGS
-
-### ✅ STRENGTHS
-
-#### 1. Error Checking Coverage: EXCELLENT
-- **502 error checks** across 66 files
-- `TORCH_CHECK` macros: Comprehensive tensor validation
-- `cudaGetLastError()`: Present in kernel launchers
-- `assert` statements: Development-time validation
-
-**Evidence:**
-```bash
-$ grep -r "TORCH_CHECK\|cudaGetLastError\|assert" robocache/ | wc -l
-502
-```
-
-#### 2. Compute Sanitizer Integration: EXCELLENT
-**File:** `.github/workflows/compute-sanitizer.yml`
-- ✅ memcheck (memory leaks, invalid access)
-- ✅ racecheck (data races, shared memory conflicts)
-- ✅ Automated CI integration (manual trigger)
-
-**Professional Assessment:** This is **NVIDIA best practice**. Very few projects have this.
-
-#### 3. Security Workflows: EXCELLENT
-**File:** `.github/workflows/security_scan.yml`
-- ✅ SBOM generation (supply chain)
-- ✅ CVE scanning (pip-audit, Trivy)
-- ✅ Dependency review (GitHub Actions)
-
-#### 4. Bounds Checking: GOOD
-**Sample from voxelization kernel:**
-```cuda
-if (point_to_voxel_idx(px, py, pz, origin, voxel_size,
- depth, height, width, vx, vy, vz)) {
- // Only proceed if within bounds
- int voxel_linear = voxel_idx_to_linear(vx, vy, vz, ...);
-}
-```
-
-#### 5. Atomic Operations: CORRECT
-**CAS loop for float max** (memory-safe):
-```cuda
-do {
- assumed = old;
- float old_val = __uint_as_float(assumed);
- float new_val = fmaxf(old_val, feat);
- old = atomicCAS(addr, assumed, __float_as_uint(new_val));
-} while (assumed != old);
-```
-
----
-
-## ⚠️ HARDENING RECOMMENDATIONS
-
-### Priority 1: Add Defensive CUDA Error Checking Macro
-
-**Current:** Error checking scattered, inconsistent
-**Recommendation:** Standardized macro for all kernel launches
-
-**Implementation:**
-```cpp
-// Add to csrc/cuda/cuda_utils.h
-#define CUDA_KERNEL_CHECK(call) \
- do { \
- call; \
- cudaError_t err = cudaGetLastError(); \
- TORCH_CHECK(err == cudaSuccess, \
- "CUDA kernel launch failed: ", cudaGetErrorString(err)); \
- err = cudaDeviceSynchronize(); \
- TORCH_CHECK(err == cudaSuccess, \
- "CUDA kernel execution failed: ", cudaGetErrorString(err)); \
- } while(0)
-
-// Usage:
-CUDA_KERNEL_CHECK(my_kernel<<>>(args));
-```
-
-**Benefit:** Catches both launch and execution errors immediately.
-
----
-
-### Priority 2: Add Input Validation Helper
-
-**Current:** Validation scattered across files
-**Recommendation:** Centralized validation for robotics constraints
-
-**Implementation:**
-```cpp
-// Add to csrc/cpp/safety_checks.h
-namespace robocache {
-namespace safety {
-
-inline void validate_trajectory_input(
- const torch::Tensor& data,
- const torch::Tensor& times,
- const char* name
-) {
- TORCH_CHECK(data.dim() == 3,
- name, " must be 3D (batch, time, features)");
- TORCH_CHECK(data.size(0) == times.size(0),
- name, " batch size mismatch");
- TORCH_CHECK(data.size(1) == times.size(1),
- name, " time dimension mismatch");
-
- // Robotics-specific: Check for NaN/Inf (sensor failures)
- TORCH_CHECK(!torch::any(torch::isnan(data)).item(),
- name, " contains NaN (sensor failure?)");
- TORCH_CHECK(!torch::any(torch::isinf(data)).item(),
- name, " contains Inf (overflow?)");
-
- // Timestamps must be monotonic increasing
- auto time_diff = times.diff(1, 1);
- TORCH_CHECK(torch::all(time_diff > 0).item(),
- name, " timestamps must be monotonically increasing");
-}
-
-} // namespace safety
-} // namespace robocache
-```
-
-**Benefit:** Catches sensor failures, malformed data before GPU execution.
-
----
-
-### Priority 3: Add Determinism Validation Test
-
-**Current:** Determinism assumed but not validated
-**Recommendation:** CI test for bit-exact reproducibility
-
-**Implementation:**
-```python
-# Add to tests/test_determinism.py
-def test_multimodal_fusion_deterministic():
- """Verify bit-exact determinism for safety-critical applications."""
- torch.manual_seed(42)
- torch.cuda.manual_seed(42)
-
- # Run same input 10 times
- inputs = create_test_inputs()
- results = []
- for _ in range(10):
- result = robocache.fuse_multimodal(**inputs)
- results.append(result.cpu())
-
- # All results must be bit-exact identical
- for i in range(1, len(results)):
- assert torch.equal(results[0], results[i]), \
- f"Non-deterministic output at iteration {i}"
-```
-
-**Benefit:** Guarantees reproducible behavior for certification/testing.
-

-- No recursive functions in kernels
-- No VLA (variable-length arrays)
-
-### Heap Overflow Risk: ✅ LOW
-- All allocations through PyTorch (managed)
-- No raw `malloc/cudaMalloc` in hot path
-- Bounds checking before indexing
-
-### Use-After-Free Risk: ✅ NONE
-- RAII patterns via PyTorch tensors
-- No manual memory management
-- Smart pointer-like semantics
-
-### Race Conditions: ✅ PROTECTED
-- Atomic operations for shared writes
-- Proper synchronization (`__syncthreads()`)
-- Compute sanitizer validation available
-
----
-
-## ROBUSTNESS FEATURES
-
-### ✅ Graceful Degradation
-- CPU fallbacks for non-CUDA systems
-- Error messages include context
-- No silent failures
-
-### ✅ Resource Management
-- CUDA streams managed by PyTorch
-- Automatic cleanup via RAII
-- No leaked resources
-
-### ✅ Error Messages
-- Descriptive error messages

-# Codex Response Evidence Log
-
-**Date Started:** 2025-11-08
-**Approach:** Evidence-based fixes, not narratives
-**Goal:** Address every Codex concern with committed code + artifacts
-
----
-
-## P0 Fixes - Critical Path
-
-### ✅ Issue #1: CPU Fallback Function Missing
-
-**Codex Finding:**
-> "The CPU benchmark harness still calls a nonexistent resample_trajectories_cpu"
-
-**Fix:** Added alias function `resample_trajectories_cpu` → `fuse_multimodal_cpu`
-
-**Evidence:**
-- **Commit:** `27e06d2`
-- **File:** `robocache/python/robocache/ops_fallback.py` lines 36-56
-- **Test:** Function exists and is importable
-- **Status:** ✅ COMPLETE
-
----
-
-### 🚧 Issue #2: Multimodal Tests Ignore Timestamps
-
-**Codex Finding:**
-> "'Correctness' tests for multimodal fusion continue to upsample each stream purely by index using torch.nn.functional.interpolate, completely ignoring the timestamp tensors"
-
-**Required:**
-- [ ] Tests with non-uniform timestamps
-- [ ] Tests with phase-shifted timestamps
-- [ ] Tests catching misaligned interpolation
-- [ ] Test execution log
-
-**Status:** 🚧 IN PROGRESS
-
----
-
-### ✅ Issue #3: CUTLASS Kernels Not Compiled
-
-**Codex Finding:**
-> "robocache/setup.py continues to build only the three reference CUDA extensions. None of the advertised CUTLASS/TMA sources are compiled or even mentioned"
-
-**Fix:** Added CUTLASS extension to setup.py, created PyBind11 bindings
-
-**Evidence:**
-- **Commit:** `32c8054`
-- **Files:**
- - `robocache/setup.py` lines 69-87: CUTLASS extension definition
- - `robocache/csrc/cpp/cutlass_ops.cpp`: 70 lines of bindings
- - `kernels/cutlass/trajectory_resample_production.cu`: H100-validated kernel
-- **Build output:** "Building 4 CUDA extensions (including CUTLASS)"
-- **Module:** `robocache._cutlass_ops`
-
-**Remaining:**
-- [ ] Build wheel locally and verify `.so` exists
-- [ ] Test import after install
-- [ ] Run on H100
-
-**Status:** ✅ INFRASTRUCTURE COMPLETE, validation pending
-
----
-
-### ⏳ Issue #4: README Claims Unsubstantiated
-
-**Codex Finding:**
-> "The public README still promises 'sub-millisecond latency,' '10-100× faster than CPU'"
-
-**Required:**
-- [ ] Every claim linked to benchmark
-- [ ] Remove unsupported claims
-- [ ] Document what ships vs what doesn't
-
-**Status:** ⏳ PENDING
-
----
-
-### ⏳ Issue #5: H100 Validation of Shipped Code
-
-**Codex Finding:**
-> Implicit - need to validate what actually ships, not local infrastructure
-
-**Required:**
-- [ ] Build wheel with CUTLASS
-- [ ] Install on H100 from wheel
-- [ ] Run benchmarks on installed package
-- [ ] Capture NCU of shipped kernels
-- [ ] Document results
-
-**Status:** ⏳ PENDING

-# README Performance Claims Audit - Codex P0
-**Date:** 2025-11-09
-**Auditor:** Expert CUDA Engineer (15+ years experience)
-**Purpose:** Systematic verification of every performance claim in README.md
-
----
-
-## Executive Summary
-
-**Status:** ⚠️ **CRITICAL DISCREPANCIES FOUND**
-
-**Findings:**
-- ❌ 3 claims CONTRADICTED by measured data
-- ✅ 2 claims VERIFIED with evidence
-- ⚠️ Multiple unsubstantiated optimization claims
-- ❌ Missing configuration details for reproducibility
-
-**Recommendation:** IMMEDIATE README update required to maintain credibility.
-
----
-
-## Detailed Audit Results
-
-### CLAIM 1: "Sub-millisecond latency - 0.018-2.6ms on H100"
-
-**Location:** README.md:23
-
-**Evidence:**
-- Source: `artifacts/h100_validation_final_results.md`
-- Measured trajectory resample: **0.0353ms** (NOT 2.6ms)
-- Measured multimodal fusion: **0.0339ms** (MATCHES 0.034ms, NOT 0.018ms)
-- Measured voxelization: **0.0205ms**
-
-**Verdict:** ⚠️ **PARTIALLY CORRECT**
-- Range is correct (all operations <1ms)
-- BUT individual values are WRONG:
- - 2.6ms trajectory claim is **73x TOO HIGH**
- - 0.018ms multimodal claim is **1.88x TOO LOW**
-
-**Required Fix:**
-```markdown
-- 🚀 **Sub-millisecond latency** - 0.021-0.035ms on H100
-```
-
-**Evidence Links:**
-- [H100 Validation Results](artifacts/h100_validation_final_results.md)
-- All operations measured with 100 iterations, 5-number summary
-
----
-
-### CLAIM 2: "10-100× faster than CPU"
-
-**Location:** README.md:24
-
-**Evidence:** ❌ **NONE FOUND**
-- No CPU baseline benchmarks in artifacts/
-- No comparison data in validation reports
-- No methodology documented
-
-**Verdict:** ❌ **UNSUBSTANTIATED**
-
-**Required Fix:**
-Either:
-1. Remove claim entirely, OR
-2. Add CPU baseline benchmarks and document methodology
-
-**Rationale:** Without CPU comparison data, this claim is marketing, not engineering.
-
----
-
-### CLAIM 3: "H100: 0.034ms | A100: 0.057ms" (Multimodal Fusion)
-
-**Location:** README.md:56
-
-**Evidence:**
-- H100: `artifacts/h100_validation_final_results.md` → 0.0339ms ✅
-- A100: Referenced in README as 0.057ms
-
-**H100 Measured:**
-- Mean: 0.0339ms
-- Std: 0.0022ms
-- P50: 0.0333ms
-
-**Verdict:** ✅ **H100 VERIFIED** (0.034ms claim matches 0.0339ms measurement)
-- A100: ⏳ NEEDS VERIFICATION (no artifacts/a100/ validation found)
-
-**Required Fix:**
-```python
-# Output: (4, 50, 588) - batch × time × (512+64+12)
-# H100: 0.034ms ± 0.002ms (measured, n=100)
-```
-
-Add measurement uncertainty and sample size.
-
----
-
-### CLAIM 4: "H100: 24 billion points/sec | A100: 21 billion points/sec"
-
-**Location:** README.md:71
-
-**Evidence:**
-- H100: `artifacts/h100_validation_final_results.md` → **24.34 B pts/sec** ✅
-- A100: ❌ NO EVIDENCE FOUND
-
-**H100 Measured:**
-- Latency: 0.0205ms
-- Throughput: **24.34 B pts/sec**
-- Config: 500K points, 128³ grid
-
-**Verdict:**
-- H100: ✅ **VERIFIED** (24.34 matches claim of 24)
-- A100: ❌ **UNSUBSTANTIATED** (no A100 validation report in artifacts/)
-
-**Required Fix:**
-```python
-# H100: 24.3 billion points/sec (measured: 0.0205ms for 500K pts)
-# A100: [REMOVE or ADD EVIDENCE]
-```
-
----
-
-### CLAIM 5: "Trajectory Resample latency: 0.0353 ± 0.0016 ms"
-
-**Location:** README.md:115 (H100 Benchmarks table)
-
-**Evidence:** ✅ **VERIFIED**
-- Source: `artifacts/h100_validation_final_results.md`
-- Mean: 0.0353ms
-- Std: 0.0016ms
-- Config: (32, 500, 256) bf16
-
-**Verdict:** ✅ **CORRECT** - This table is accurate.
-
-**Note:** This CONTRADICTS the "0.018-2.6ms" range in line 23. The 2.6ms claim is from an UNKNOWN source.
-
----
-
-### CLAIM 6: "Vectorized BF16 loads (4× throughput vs scalar)"
-
-**Location:** README.md:161
-
-**Evidence:** ❌ **NONE FOUND**
-- No benchmark comparing vectorized vs scalar loads
-- No NCU metrics showing 4x difference
-- Architecture comment, not measured claim
-
-**Verdict:** ⚠️ **THEORETICAL** - Likely correct (BF16x4 = 8 bytes, BF16x1 = 2 bytes), but NOT measured
-
-**Required Fix:**
-```markdown
-- Vectorized BF16 loads (4-element vectors, 4x bandwidth vs scalar)
-```
-
-Change from "throughput" (requires measurement) to "bandwidth" (architectural fact).
-
----
-
-### CLAIM 7: "Coalesced memory access (>95% efficiency)"
-
-**Location:** README.md:162
-
-**Evidence:** ❌ **NONE FOUND**
-- NCU reports do NOT contain "Global Memory Access Efficiency" metric
-- No memory transaction analysis in artifacts/
-
-**Verdict:** ❌ **UNSUBSTANTIATED**
-
-**NCU Data Available:**
-- DRAM BW utilization: 51.82% (voxelization)
-- DRAM BW utilization: 1.59% (trajectory resample)
-- L1 cache hit rate: 99%+ (trajectory/multimodal)
-
-**Required Fix:**
-Remove ">95% efficiency" claim OR add NCU memory transaction analysis to artifacts/.
-
-**Alternative (using available data):**
-```markdown
-- L1-resident workloads (99%+ cache hit rate for fusion/resample)
-- High memory bandwidth (51% DRAM utilization for voxelization)
-```
-
----
-
-### CLAIM 8: NCU Metrics Table (Lines 173-177)
-
-**Location:** README.md:173-177
-
-**Claims:**
-- Trajectory Resample: 0.05% DRAM BW, 1.27% SM, 12.48% warps, 99%+ L1
-- Multimodal Fusion: 0.03% DRAM BW, 2.15% SM, 12.49% warps, 99%+ L1
-- Voxelization: 54.17% DRAM BW, 14.06% SM, 64.83% warps, N/A L1
-
-**Evidence:** ⏳ **NEEDS VERIFICATION**
-- Files referenced: `robocache/profiling/NCU_H100_TRAJECTORY_RESAMPLE.md`
-- Need to check if these numbers are in the files
-
-**Action:** Read NCU profiling files to verify.
-
----
-
-### CLAIM 9: "End-to-end latency: 1.56ms/step (12.84× faster than 20ms target)"
-
-**Location:** README.md:198
-
-**Evidence:** ⏳ **NEEDS VERIFICATION**
-- Referenced file: `robocache/profiling/NSIGHT_SYSTEMS_H100.md`
-- Need to check if this timeline analysis exists
-
-**Action:** Read Nsight Systems file to verify.
-
----
-
-### CLAIM 10: "Throughput: 20,548 episodes/sec"
-
-**Location:** README.md:200
-
-**Evidence:** ⏳ **NEEDS VERIFICATION**
-- Source: Nsight Systems report
-- Calculation: 1 / (1.56ms) = 641 ops/sec (NOT 20,548!)
-
-**Possible Issue:**
-- 20,548 may be "samples per second" not "episodes per second"
-- OR calculation is wrong
-- OR this is a different metric
-
-**Action:** Verify with Nsight Systems report.
-
----
-
-## Critical Issues Summary
-

-- Multimodal fusion: 0.0339ms
-- Trajectory resample: 0.0353ms
-- Source: `artifacts/h100_validation_final_results.md`
-
-**Rationale:** The "2.6ms" claim is **73x too high** compared to measured data. Replace with actual measured range.
-
----
-
-### 2. Remove Unsubstantiated CPU Speedup Claim (Line 24)
-
-**BEFORE:**
-```markdown
-- ⚡ **10-100× faster than CPU** - Validated with Nsight profiling
-```
-
-**AFTER:**
-```markdown
-- ⚡ **GPU-accelerated with BF16** - CUDA kernels with vectorized loads
-```
-
-**Evidence:** ❌ NONE - No CPU baseline benchmarks exist
-
-**Rationale:** Without CPU comparison data, the "10-100×" claim is unsubstantiated. Replace with factual statement about GPU optimization.
-
----
-
-### 3. Add Measurement Uncertainty to Quick Start (Line 56)
-
-**BEFORE:**
-```python
-# H100: 0.034ms | A100: 0.057ms
-```
-
-**AFTER:**
-```python
-# H100: 0.034ms ± 0.002ms (n=100) | A100: 0.057ms (P50)
-```
-
-**Evidence:**
-- H100: Mean 0.0339ms, Std 0.0022ms from artifacts/h100_validation_final_results.md
-- A100: No detailed validation found, but P50 metric noted
-
-**Rationale:** Add measurement rigor (sample size, uncertainty)
-
----
-
-### 4. Update Voxelization Comment (Line 71)
-
-**BEFORE:**
-```python
-# H100: 24 billion points/sec | A100: 21 billion points/sec
-```
-
-**AFTER:**
-```python
-# H100: 24.3 billion points/sec (500K pts @ 0.0205ms)
-# A100: [Evidence pending - see artifacts/a100_validation.md]
-```
-
-**Evidence:**
-- H100: 24.34 B pts/sec measured
-- A100: ❌ NO VALIDATION FOUND in artifacts/
-
-**Rationale:** H100 claim verified, A100 claim unsubstantiated
-
----
-
-### 5. Remove Memory Efficiency Claim (Line 162)
-
-**BEFORE:**
-```markdown
-- Coalesced memory access (>95% efficiency)
-```
-
-**AFTER:**
-```markdown
-- L1-resident workloads (99%+ cache hit rate for fusion/resample)
-```
-
-**Evidence:**
-- NCU reports show 99%+ L1 hit rate
-- NO "memory access efficiency" metric found
-- NCU data: 0.05% DRAM (trajectory), 0.03% DRAM (multimodal) → L1-resident
-
-**Rationale:** Replace unsubstantiated ">95%" with measured L1 hit rate
-
----
-
-### 6. Clarify Vectorization Claim (Line 161)
-
-**BEFORE:**
-```markdown
-- Vectorized BF16 loads (4× throughput vs scalar)
-```
-
-**AFTER:**
-```markdown
-- Vectorized BF16 loads (4-element vectors, 4× bandwidth vs scalar)
-```
-
-**Evidence:** Architectural fact (BF16x4 = 8 bytes vs BF16x1 = 2 bytes)
-
-**Rationale:** Change "throughput" (requires measurement) to "bandwidth" (architectural fact)
-
----
-
-## NCU Metrics Table Verification (Lines 173-177)
-
-**Current README Claims:**
-| Kernel | DRAM BW | SM Throughput | Warps Active | L1 Hit Rate |

-**Memory overhead:** Need to check line 89-100 for "0.15%" claim...
-
-From NSIGHT_SYSTEMS_H100.md line 89:
-```
-| memset | 72.3% | 177,666 | 220 | 808 |
-```
-

-
-## Performance Targets (Estimated)
-
-Based on NVIDIA's published Blackwell specs (2× H100 performance):
-
-| Operation | H100 Baseline | B100 Target | B200 Target |
-|-----------|---------------|-------------|-------------|
-| Trajectory (32×500×256) | 2.605ms | <1.3ms | <1.0ms |
-| Multimodal (3-stream) | <1ms | <0.5ms | <0.4ms |
-| Voxelization (1M pts) | <0.5ms | <0.25ms | <0.2ms |
-| DRAM Bandwidth | 3.0 TB/s | 4+ TB/s | 4+ TB/s |
-| Tensor Core TFLOPS | 990 (FP16) | 2000+ (FP8) | 2000+ (FP8) |
-
-**Key Optimizations for Blackwell:**
-1. Enhanced FP8 precision (Transformer Engine v2)
-2. Larger WGMMA tiles (256×256 vs 128×128)
-3. Improved TMA (Tensor Memory Accelerator)
-4. Larger L2 cache (expected 60+ MB)
-
----
-
-## Risk Mitigation
-
-### Risk 1: Hardware Unavailable in Q1 2026
-**Mitigation:**
-- Continue H100/A100 validation
-- Simulate SM100 with SM90 + newer CUTLASS APIs
-- Defer Blackwell-specific optimizations to Q2 2026
-
-### Risk 2: CUDA 14.0 API Changes
-**Mitigation:**
-- Abstract kernel APIs via CUTLASS templates
-- Maintain backward compatibility with SM80/SM90
-- Beta test with CUDA 14.0 RC releases
-
-### Risk 3: Budget Constraints
-**Mitigation:**
-- Prioritize cloud access over self-hosted
-- Leverage NVIDIA developer program
-- Defer DGX B200 until Series A funding
-
-### Risk 4: CI/CD Integration Complexity
-**Mitigation:**
-- Test GitHub Actions self-hosted runner setup with H100 first
-- Document runner provisioning and security
-- Use containerized builds (Docker) for reproducibility
-
----
-
-## Success Criteria
-
-1. ✅ **Q1 2026:** SM100 kernel compilation successful (cloud or dev program)
-2. ✅ **Q2 2026:** Performance benchmarks vs H100 (<2× speedup validated)

-# RoboCache Production Readiness Audit
-**Date:** November 7, 2025
-**Auditor:** Expert CUDA/NVIDIA Engineer (15+ years)
-**Status:** COMPREHENSIVE GAP ANALYSIS
-
----
-
-## Executive Summary
-
-**Current State:** RoboCache has production-grade CUDA kernels but lacks industrial-strength infrastructure, validation, and operational readiness.
-
-**Risk Level:** 🟡 MODERATE
-- Core CUDA functionality validated on H100/A100
-- Infrastructure gaps block production deployment
-- Missing operational observability for ROS 2/Isaac
-
-**Recommended Action:** Implement P0 workstreams before production deployment.
-
----
-
-## Gap Analysis by Workstream
-
-### 1) Demonstrable CUDA Production Path (P0)
-
-**Current State:**
-
-✅ **Strengths:**
-- CUDA kernels compile and work (`setup.py` with `CUDAExtension`)
-- H100/A100 validation complete
-- PyTorch integration functional
-
-❌ **Gaps:**
-- No prebuilt wheels for distribution
-- No explicit fatbin generation with `-gencode` flags
-- Build process not deterministic (recompiles every install)
-- No CI on real GPU hardware
-- Missing `CMakeLists.txt` for robust builds
-
-**Files to Audit:**
-```bash
-robocache/setup.py # Current build script
-robocache/csrc/cuda/*.cu # CUDA kernels (OK)
-robocache/csrc/cpp/*.cpp # PyTorch bindings (OK)
-```
-
-**Missing:**
-```
-/cpp/CMakeLists.txt # Needed
-/packaging/build_wheel.sh # Needed
-/.github/workflows/gpu_ci.yml # Needed
-```
-
-**Priority:** 🔴 P0 - CRITICAL
-
----
-
-### 2) Reproducible Performance Evidence (P0)
-
-**Current State:**
-
-✅ **Strengths:**
-- H100 validation: 1.79ms/step, 541.7 steps/sec
-- A100 validation: Performance metrics captured
-- NCU/NSys profiles exist for individual kernels
-
-❌ **Gaps:**
-- No formal benchmark harness in repository
-- Performance data not tied to git SHA
-- No CI performance regression gates
-- Missing golden datasets
-- No threshold enforcement
-
-**Files to Audit:**
-```bash
-robocache/tests/perf/ # Exists but not formalized
-docs/validation/H100_VALIDATION_COMPLETE.md # Good but not automated
-```
-
-**Missing:**
-```
-/benchmarks/harness.py # Needed
-/benchmarks/smoke.py # Needed for CI
-/benchmarks/golden_data/ # Needed
-/.github/workflows/perf_regression.yml # Needed
-```
-
-**Priority:** 🔴 P0 - CRITICAL
-
----
-
-### 3) Robust CPU/Torch Fallbacks (P0)
-
-**Current State:**
-
-✅ **Strengths:**
-- CUDA kernels well-optimized
-
-❌ **Gaps:**
-- **NO CPU FALLBACKS EXIST**
-- Python API requires CUDA (fails on CPU-only hosts)
-- Isaac Sim demo has baseline PyTorch but it's not a fallback path
-- Tests skip on non-CUDA hosts instead of testing fallbacks
-
-**Files to Audit:**
-```bash
-robocache/python/robocache/__init__.py # No fallback logic
-robocache/tests/test_*.py # Skip on CPU, don't test fallbacks
-```
-
-**Required:**
-```python
-# robocache/python/robocache/ops_fallback.py
-def resample_trajectories_cpu(vision, vision_times, ...):
- # Vectorized PyTorch implementation
- pass
-```
-
-**Priority:** 🔴 P0 - CRITICAL (blocks CPU-only CI and testing)
-
----
-
-### 4) API ↔ Kernel Parity (P0)
-
-**Current State:**
-
-✅ **Strengths:**
-- Public API matches documentation
-- Kernels are properly exposed via PyTorch bindings
-
-⚠️ **Concerns:**
-- Need to verify: Are multimodal operations truly fused, or chained?
-- Need to confirm: Single kernel launch per API call?
-
-**Files to Audit:**
-```bash
-robocache/csrc/cpp/multimodal_ops.cpp # Check for fusion
-robocache/python/robocache/__init__.py # API surface
-```
-
-**Action Required:**
-- Profile with NSys to confirm single-launch semantics
-- Document fusion strategy in code comments
-- Add tests that assert kernel launch counts
-
-**Priority:** 🟡 P0 - VERIFY (audit required)
-
----
-
-### 5) Operational Readiness for ROS 2/Isaac (P1)
-
-**Current State:**
-
-❌ **Gaps:**
-- **NO operational instrumentation**
-- No structured logging
-- No metrics/counters
-- No health checks or watchdogs
-- No ROS 2 example node with observability
-- No stress tests or fault injection
-
-**Missing:**
-```
-/robocache/python/robocache/logging.py # Needed
-/robocache/python/robocache/metrics.py # Needed
-/examples/ros2_node/ # Needed
-/tests/stress/ # Needed
-```
-
-**Priority:** 🟡 P1 - HIGH (required before production)
-
----
-
-### 6) Validation Matrix & CI (P1)
-
-**Current State:**
-
-✅ **Strengths:**
-- Unit tests exist for correctness
-- Performance tests exist
-- Compute Sanitizer workflow added
-
-❌ **Gaps:**
-- No determinism tests
-- No mixed-precision accuracy tests
-- No multi-GPU DDP tests
-- No backward compatibility tests
-- No nightly CI matrix
-- CI runs on CPU, not GPU
-
-**Files to Audit:**
-```bash
-robocache/tests/test_*_correctness.py # Good but incomplete
-.github/workflows/ci.yml # No GPU runner
-.github/workflows/compute-sanitizer.yml # Good but no real GPU
-```
-
-**Missing:**
-```
-/tests/test_determinism.py # Needed
-/tests/test_mixed_precision.py # Needed
-/tests/test_multi_gpu_ddp.py # Needed
-/tests/test_backward_compat.py # Needed
-/.github/workflows/nightly_matrix.yml # Needed
-```
-
-**Priority:** 🟡 P1 - HIGH
-
----
-
-### 7) Evidence & External Validation (P2)
-
-**Current State:**
-
-✅ **Strengths:**
-- Validation reports exist and are comprehensive
-- NCU/NSys captures documented
-
-❌ **Gaps:**
-- No continuous performance dashboard
-- No reproducible hardware-lab scripts
-- No postmortem documentation for failure scenarios
-
-**Missing:**
-```
-/docs/perf_dashboard.md # Needed
-/scripts/lab/ # Needed
-/docs/postmortems/ # Needed
-/bench_artifacts// # Needed
-```
-
-**Priority:** 🟢 P2 - NICE TO HAVE
-
----
-
-## Critical Path Analysis
-
-### Blocking Issues (Must Fix Before Production)
-
-1. **🔴 P0-1: CPU Fallbacks**
- - **Impact:** Repository cannot be tested on CPU-only CI
- - **Effort:** 2-3 days
- - **Files:** `robocache/python/robocache/ops_fallback.py` + tests
-
-2. **🔴 P0-2: Build System Hardening**
- - **Impact:** Cannot distribute wheels, builds are fragile
- - **Effort:** 3-4 days
- - **Files:** `CMakeLists.txt`, `pyproject.toml`, wheel build scripts
-
-3. **🔴 P0-3: Benchmark Harness + CI**
- - **Impact:** Cannot detect performance regressions
- - **Effort:** 2-3 days
- - **Files:** `benchmarks/`, `.github/workflows/perf_regression.yml`
-
-4. **🔴 P0-4: GPU CI Runners**
- - **Impact:** Cannot validate on real hardware in CI
- - **Effort:** 1-2 days (setup self-hosted runner or cloud GPU)
- - **Dependency:** Requires infrastructure
-
----
-
-## Risk Register
-
-| Risk | Probability | Impact | Mitigation |
-|------|-------------|--------|------------|
-| CPU fallback performance collapse | HIGH | HIGH | Vectorize with PyTorch ops, enforce benchmarks |
-| CUDA build fragility on new systems | MEDIUM | HIGH | CMake + explicit `-gencode`, test on clean VMs |
-| Performance regression undetected | HIGH | MEDIUM | CI perf gates with thresholds |
-| Operational blind spots in production | MEDIUM | HIGH | Add logging, metrics, health checks |
-| Multi-GPU correctness issues | LOW | HIGH | Add DDP tests, validate with NCCL-tests |

-## 1. Multi-GPU Validation
-
-### H100 PCIe (SM90 - Hopper)
-
-**Hardware:**
-- GPU: NVIDIA H100 PCIe 80GB
-- Driver: 545.x
-- CUDA: 13.0
-- Compute Capability: 9.0
-
-**Results:**
-```
-GPU: NVIDIA H100 PCIe
-Batch=32, Source=500, Target=250, Dim=256
-
-RoboCache + Transformer Training (H100)
-============================================================
-Total time: 1.40s (100 steps)
-Avg step: 14.04ms
-Throughput: 2279.4 episodes/sec
-============================================================
-✓ Kernel compiled and ran successfully on H100
-```
-
-**NCU Metrics:**
-- DRAM Throughput: 0.05% (L1-resident - **OPTIMAL**)
-- SM Throughput: 1.27%
-- Warps Active: 12.48%
-- L1 Load Sectors: 259,077 (8.3 MB)
-
-**Analysis:** Kernel is L1 cache-resident and memory-latency optimized. Low DRAM utilization is proof of optimal caching, not a deficiency.
-
-**Documentation:** [`VALIDATION_H100.md`](VALIDATION_H100.md), [`profiling/NCU_H100_TRAJECTORY_RESAMPLE.md`](profiling/NCU_H100_TRAJECTORY_RESAMPLE.md)

-
-### A100 SXM4 (SM80 - Ampere)
-
-**Hardware:**
-- GPU: NVIDIA A100-SXM4-80GB
-- Driver: 565.57.01
-- CUDA: 12.1 / 13.0
-- Compute Capability: 8.0
-
-**Results:**
-```
-GPU: NVIDIA A100-SXM4-80GB
-CUDA: 12.1
-
-RoboCache + Transformer Training (A100)
-============================================================
-Total time: 1.83s (100 steps)
-Avg step: 18.28ms
-Throughput: 1750.8 episodes/sec
-============================================================
-✓ A100 (SM80) validation PASSED
-```
-
-**Performance Scaling:**
-- H100: 14.04ms (baseline)
-- A100: 18.28ms (1.30x slower)
-- Ratio matches memory BW difference (0.75x)
-
-**Analysis:** Performance scales correctly with hardware capabilities. Confirms memory-latency optimization strategy.
-
-**Documentation:** [`VALIDATION_A100.md`](VALIDATION_A100.md)

----
-
-## 2. Kernel Performance Analysis
-
-### Trajectory Resampling
-
-**Workload:**
-- Input: Variable-frequency sensor data (30-100Hz)
-- Output: Uniform 50Hz resampling
-- Algorithm: Binary search + linear interpolation (BF16)
-
-**Performance:**
-
-| Metric | H100 | A100 |
-|--------|------|------|
-| Kernel Latency | ~0.02ms | ~0.02ms |
-| End-to-End | 14.04ms | 18.28ms |
-| Throughput | 2279 eps/s | 1751 eps/s |
-
-**Memory Hierarchy (NCU - H100):**
-- L1 Cache: 99%+ hit rate
-- DRAM: 0.05% utilization (L1-resident)
-- Pattern: Memory-latency bound (optimal for binary search)
-
-**Optimization Status:**
-- ✅ Current design optimal for workload
-- ✅ L1-resident caching working as intended
-- ⚠️ Future: warp shuffles (1.2-1.5x potential gain)
-- ⚠️ Future: persistent threads (1.1-1.3x for large batches)
-
----
-
-## 3. Integration Validation
-
-### PyTorch C++ Extension (JIT)
-
-**Build System:**
-- JIT compilation via `torch.utils.cpp_extension.load()`
-- Automatic architecture targeting (`-arch=sm_80`, `-arch=sm_90`)
-- No manual CMake required for users
-
-**Tested:**
-- ✅ H100: CUDA 13.0 + PyTorch 2.x
-- ✅ A100: CUDA 12.1/13.0 + PyTorch 2.5.1
-- ✅ BF16 tensor support
-- ✅ Autograd integration
-
-**Example:**
-```python
-from torch.utils.cpp_extension import load
-
-robocache = load(
- name='robocache_cuda',
- sources=['resample.cu'],
- extra_cuda_cflags=['-O3', '-arch=sm_90']
-)
-
-# Use in training loop
-resampled = robocache.resample_trajectories(vision, times_src, times_tgt)
-out = model(resampled.float())
-loss.backward()
-```
-
----
-
-### End-to-End Training Loop
-
-**Model:** 4-layer Transformer (8 heads, 1024 FFN, ~5M params)
-
-**Pipeline:**
-1. Generate synthetic RT-X data on GPU
-2. RoboCache resampling (30Hz/100Hz → 50Hz)
-3. Transformer forward pass
-4. Loss computation
-5. Backpropagation
-6. Optimizer step
-
-**Results:**
-- H100: 14.04ms/step (2279 eps/sec)
-- A100: 18.28ms/step (1751 eps/sec)
-- **Zero CPU bottleneck** - all data stays on GPU
-
-**Validated:** [`benchmarks/rtx_real_world_benchmark.py`](benchmarks/rtx_real_world_benchmark.py)
