osobhandClaude Sonnet 5	4aaa36a57a	style: cargo fmt --workspace (whitespace/wrapping only, no semantic change) ... Whole-workspace rustfmt pass picked up while iterating on Mamba GPU backward work. Verified formatting-only via diff sampling; no logic changed. Co-Authored-By: Claude Sonnet 5 <[email protected]>	2026-08-10 07:09:36 -07:00
Omar SobhandClaude Sonnet 4.6	1eb89c5b2b	feat(perf): GPU perf batch 1 — FP8, FA3 Blackwell, CUDA Graphs, SnapKV, prefix cache ... Item 1 — CUDA Graphs wiring (rtx-transformers) - Added `enable_cuda_graphs: bool` (default false) + `cuda_graph_warmup_iters: usize` (default 3) to `TrainingConfig` - Wired 3-phase state machine into `training_loop.rs` (warmup → capture → replay) gated on `#[cfg(feature = "cuda")]`; stream plumbing stubbed with TODO pending `CudaStreamHandle` threading Item 2 — FP8 E4M3/E5M2 training infrastructure (rtx-tensor, rtx-transformers) - `fp8_cast.cu`: dual-path CUDA kernels — SM_89+ uses `<cuda_fp8.h>` native `__nv_cvt_*` intrinsics; older SM uses software bit-manipulation fallback - `fp8_cast.rs`: host-side CPU casting + `#[cfg(feature = "cuda")]` GPU stubs - `fp8_gemm.rs`: bit-accurate E4M3 decoder/encoder, BF16 round-trip utils, CPU reference matmul with cuBLASLt GPU path documented inline; 12 unit tests - `training_config.rs`: `fp8_training: bool`, `fp8_e4m3_forward: bool` - `linear.rs` (modular): `fp8_mode: bool` field + forward dispatch stub - build.rs: registers `fp8_cast.cu` alongside existing `element_wise.cu` - 22 FP8 unit tests — all pass Item 3 — FlashAttention-3 Blackwell (WGMMA + TMA + warp specialization) - `flash_attention_v3_forward.cu`: SM_90+ warp-specialised producer/consumer kernel (producer TMA-loads K/V tiles, consumers run WMMA as portable WGMMA proxy); SM_89+ FP8 header path; SM<90 standard FA2-style WMMA fallback - `flash_v3_forward.rs`: NVRTC wrapper (`compile_ptx` via `include_str!`), `FlashV3ForwardKernel::new/is_supported/forward`; 6 unit tests - `backend_selector.rs`: `SdpaBackend::FlashAttentionV3`, `for_compute_capability`, `supports_flash_v3` (major >= 9), FA3 scoring (0.98/0.90/0.70), 2× speedup estimate - `kernels/simple.rs`: `v3_kernel: Option<FlashV3ForwardKernel>` in `FlashCudaKernels` - Fixed pre-existing `Device::Cpu` cfg-gate bug in `tensor/creation.rs` - 8 new FA3 backend tests + 6 kernel unit tests; 50 total pass Item 4 — SnapKV attention-score eviction + prefix caching (rtx-inference, rtx-serving-api) - `prefix_index.rs`: `PrefixIndex` with 8MB Zobrist hash table (Knuth MMIX LCG seed), `compute_hash/lookup/insert/remove/remove_page`; 10 unit tests - `eviction.rs`: `AttentionScoreEviction` struct — `accumulate_scores` + `select_evict_positions` (retain top keep_ratio + last recent_window); 7 unit tests - `types.rs`: `EvictionPolicy::AttentionScore { keep_ratio, recent_window }` + `KvCacheConfig::enable_prefix_caching` - `paged_kv_cache.rs`: `prefix_index: Option<PrefixIndex>` + `lookup_prefix / register_prefix / unregister_prefix_page / prefix_caching_enabled` methods - `config.rs` (serving-api): `enable_prefix_sharing: true` (was false), `snapkv_keep_ratio: 0.6`, `snapkv_recent_window: 32` - Fixed 12 pre-existing test errors (spurious `.await` on sync constructors) - 17 SnapKV/prefix tests pass Total: 918 lib tests pass across rtx-tensor, rtx-flash-attention, rtx-transformers, rtx-inference. Zero new failures. Co-Authored-By: Claude Sonnet 4.6 <[email protected]>	2026-06-26 19:56:39 +00:00
Omar SobhandClaude Sonnet 4.6	39b7ef12f4	fix(tests): green-bar rtx-transformers and rtx-distributed test suites ... - Fix 35 doctest failures in Phase 2/3 modules (no_run annotations, missing imports, wrong API calls, Result context issues) - Fix test_validation_framework_creation: assert updated to 1e-3 default - Fix test_report_serialization: replace exact f64 equality with epsilon comparison - Fix rtx-distributed recovery/tests.rs: add missing ProcessGroup import, use recovery_stats().wal_buffer_size instead of private field access All rtx-transformers and rtx-distributed tests now pass.

Omar SobhandClaude Sonnet 4.6	a08adfbf57	fix(gaps): G4 — re-enable all rtx-transformers Phase 2/3 modules (222 compile errors fixed) ... Uncommented all deferred modules in lib.rs and fixed API drift across ~60 files in 9 module groups: continual, curriculum, meta, modular, neural_ode, graph, kan, perceiver, distributed/pipeline_parallelism. Common patterns fixed across modules: - Tensor::randn/zeros/ones([a,b]) → (&[a,b], device)? (slice + Result) - Result<T, TensorError> → .map_err(Into::into)? in TransformerError contexts - Device by value → &device references - &Tensor where Tensor expected → .clone() - tensor.relu()/tanh()/sigmoid() as methods not ops functions - Tensor arithmetic returning Result: (a + b)? → (a.clone() + b)? - shape literals → shape.dims() for Shape type - sum(n) → sum(Some(n)), mean(None) → mean(&[], false) - i64 indices → usize where required - backward(x) → backward(x, None) - Borrow conflicts on self.field resolved by extracting to locals before mut borrow - BatchingStats private fields → pub(crate) - TransformerError::Serialization → ::SerializationError - Add scalar to tensor: (t + 0.1)? → t.add_scalar(0.1)?
