osobhandClaude Fable 5	a0bf29461b	fix(streaming): real inference backend wiring and lifecycle fixes; full suite green ... - token_generator: backend is now an optional real rtx-inference engine (RwLock<Option<Arc<InferenceEngine>>>) with ServingTokenizer support; set_backend/set_tokenizer plumbing through StreamingServer - connection_manager: ConnectionPool::acquire no longer errors when the idle cache is full — creates fresh connections up to max_connections - streaming_server: ServerState::Running on construction; stream_inference generates one token per step (chunk_size semantics) - lifecycle bugs surfaced by the newly-compiling integration tests: * start(): broadcast control-channel send with zero subscribers was treated as fatal ("channel closed") in RealtimePipeline, EdgeComputingManager, MonitoringSystem — now tolerated * stop(): AdaptiveProcessor/EdgeComputingManager/MonitoringSystem awaited worker interval loops that never exit (test hung 5h) — workers are now aborted with cancellation-aware join - integration_tests: removed stale .await on now-synchronous methods cargo test -p rtx-streaming: 55 lib + 8 integration + 6 aux, all passing.

osobhandClaude Fable 5	73102b71cf	feat(transformers): real compute in orchestrator modalities and attention planner ... - orchestrator_core: execute_classical is genuine seeded QKV self-attention; execute_flash_attention delegates to rtx_flash_attention::flash_attention_forward (8-head reshape, clear Err on indivisible hidden); execute_hybrid composes the two; execute_edge/execute_distributed return explicit "modality not implemented" errors instead of fake success — which makes the previously-dead fallback_modalities retry loop real. - tensor_core_kernels: AttentionComputationOptimizer::execute dispatches Standard/Online to scaled_dot_product_attention, Flash to rtx-flash-attention, Approximated to an explicit Err (no approximation kernel exists; refuses to compute exact attention under an approximated label). - 10 new always-on tests incl. flash-vs-standard 1e-3 agreement and an Edge->Distributed->Classical fallback end-to-end. - docs/consolidation.md updated: both entries moved from scaffolding/no-op-stub status to real dispatch descriptions. 982 rtx-transformers lib tests pass.

osobhandClaude Fable 5	fce6cef262	docs: JEPA roadmap — GPU resume re-upload done; remaining items need multi-GPU ... Co-Authored-By: Claude Fable 5 <[email protected]>	2026-07-10 03:59:48 -07:00
osobhandClaude Fable 5	a755627269	feat(jepa): GPU weight re-upload on checkpoint resume ... GpuViTEncoder gains upload_weights (extracted from construction), cpu_weights_mut, and reupload_weights; JepaTrainerV2 exposes context_encoder_as_any_mut for backend-specific downcasts. The runner resume path now restores checkpoint fields into the GPU encoder's host copy and pushes them back to the device buffers — previously GPU resume restored only the step counter with a warning. If re-upload fails after host restore, the run aborts rather than training on stale device weights. Verified live on the RTX 5060 Ti: train 20 steps -> resume from the .jepa binary with total_steps=30 -> "Resumed from step 20", exactly 10 further steps, eval runs, no warnings. New tests: GPU output changes after host mutation + re-upload; CPU-target re-upload is a no-op Ok. 972 CPU tests / 37 GPU jepa_gpu tests pass.

osobhandClaude Fable 5	ac3f2af06b	feat(jepa): eval in the training loop, NCCL GPU AllReduce, GPU checkpointing ... - Eval: run_jepa_training now runs k-NN (k=5) + linear-probe evaluation every eval_every steps and at the end (deduped when aligned); JepaEvalResult recorded in JepaTrainingSummary (final_knn_acc / final_probe_acc), printed by the CLI, appended as an # eval section to the metrics CSV. Probe set is deterministic LCG synthetic (offset seed, never aliases training batches) or real shard labels when loaded. - NCCL: real GPU-direct AllReduce backend behind the new `nccl` feature (cudarc/nccl, dlopen-based so builds don't need libnccl). NCCL unique id is bootstrapped over the existing TCP rendezvous (master_port+137); data path is htod -> ncclAllReduce(Sum) -> dtoh -> mean. catch_unwind guards cudarc's panic-on-missing-lib so training falls back instead of aborting. Verified for real on the RTX 5060 Ti: single-rank GPU all_reduce identity test passes (26/26 with --features nccl). - GPU checkpointing/eval: JepaTrainerV2::context_encoder_cpu_weights() exposes host-side weights for both CPU and GPU encoders (GpuViTEncoder::cpu_weights); checkpoint save and eval now work for GPU training runs (verified: .jepa binaries written and 2 eval passes during a live GPU CLI run). Resume with a GPU encoder restores the step counter and warns that weight re-upload is not yet implemented rather than silently training on stale weights. 125 runner/distributed/vit tests pass; CLI 8/8; cuda check clean.

osobhandClaude Fable 5	19b6581f9c	feat(jepa): extended GPU training, data pipeline, integration, and cargo config ... - jepa_gpu: remove the bring-up 2-block cap; full-depth GPU-resident ViT verified against a full-depth CPU reference on the RTX 5060 Ti (depth-12 ViT-Tiny max_rel_err <= 6.6e-5). CpuViTEncoder's own hidden min(depth,2) cap removed too — CPU-path callers now get the model they configured. - jepa_distributed: real TCP parameter-server AllReduce backend (rendezvous handshake with world-size/rank validation, length- prefixed f32 payloads, connect/read/accept timeouts, connect retry until deadline so early peers survive rank 0 still computing); jepa_runner wires it for world_size > 1 and fails hard on collective errors. Two-rank loopback training run covered by test. - rtx-jepa-cli (new crate): rtx-jepa binary with train/bench/plan/ validate subcommands driving JepaRunConfig, run_jepa_training, run_jepa_benchmark, and ClusterTrainingPlan (plan --emit-config round-trips through a config serializer). GPU bench on this node: 86k patches/sec vs 1.3k CPU (~64x). - ViTSizeStr::Micro (d=32, depth=2) added as an explicit test/smoke size now that no hidden caps keep full-size configs cheap; heavy tests moved onto it (rtx-transformers suite: 367s -> 5s, and the runner subset had ballooned to 35min at full depth before this). 966 lib tests pass; 35/35 jepa_gpu with cuda; 8/8 CLI tests.

osobhandClaude Fable 5	b6440905e7	feat(jepa): gzip-compressed WebDataset shard support ... read_webdataset_shard detects the gzip magic bytes (1F 8B, not extension) and decompresses via flate2 before tar parsing; WebDatasetShard::load no longer rejects .tar.gz/.tgz. Round-trip test writes a real gzipped tar and loads it back. Co-Authored-By: Claude Fable 5 <[email protected]>	2026-07-09 22:37:05 -07:00
osobhandClaude Fable 5	4ba1b78215	docs(consolidation): audit outcome — flagged MoE/flash-attn duplicates are not duplicates ... Call-site rewrite pass audited every flagged site; none needed consolidation: metal_moe is an API-consistent backend specialization, modular/router.rs is module-level (not expert-token) routing, glam.rs is disabled dead code with a pre-existing bug (noted for whoever re-enables it), and the three flash-attention "reimplementations" turn out to be planner scaffolding, no-op stubs, and a doc comment — no attention math exists to delegate. jepa_gpu's attention is documented as part of the fused GPU ViT block by design. Verified no regressions: rtx-transformers 961 lib tests pass, jepa_gpu 34/34 with cuda, rtx-training cuda check clean. Co-Authored-By: Claude Fable 5 <[email protected]>	2026-07-09 22:30:35 -07:00
osobhandClaude Fable 5	fdc1432072	feat(jepa): full GPU-resident ViT block on CUDA ... jepa_gpu.rs rewrite: all GEMMs (QKV, attention scores via a single cuBLAS call with folded 1/sqrt(dk) scale, weighted sum, projections, FFN) plus layernorm/GELU/bias/residual kernels now operate on device-resident CudaSlice buffers; new nvrtc kernels for numerically stable row softmax and head extract/scatter replace the CPU reorder loops. Two host transfers remain per encode(): patch-token upload and final output download. Fallback is now genuine-unavailability only (no device / feature off / kernel compile failure); per-op errors in live GPU mode are hard errors instead of silent per-op CPU downgrades. Parity vs CpuViTEncoder verified on RTX 5060 Ti / CUDA 13.1: max_rel_err <= 3.1e-5 across tiny/Tiny-192 configs (tolerance 1e-3). 34/34 jepa_gpu tests pass with --features cuda; 33/33 CPU-only. CLAUDE.md JEPA "Next" list updated to reflect completed GPU wiring, WebDataset reading, and cluster-plan consumption. Co-Authored-By: Claude Fable 5 <[email protected]>	2026-07-09 22:10:27 -07:00
osobhandClaude Fable 5	e080748d88	feat(demos,inference): wire simulation demos to real compute; fix embedding lookup and weight-name aliases ... Demos: - rtx-distllm-demo: real rtx-tensor weights per shard, real scaled-dot-product attention forward, metrics measured (Instant) instead of hardcoded constants; network topology remains a documented simulation fed by real tensor byte sizes. - rtx-model-zoo: MockInferenceEngine deleted; RealInferenceEngine loads a tiny real transformer into rtx_inference::InferenceEngine and runs genuine engine.infer per request; domain outputs are explicitly- labeled toy proxies derived from real output tokens. - rtx-inference-profiler: mock models deleted; profiles real matmul/softmax pipelines on rtx-tensor with measured latency/memory. Inference-path bugs the demos surfaced (fixed here): - ForwardPass::apply_embedding misused Tensor::gather for the embedding lookup — gather returns the indices' shape, silently dropping the hidden dim and breaking every downstream broadcast. Now uses the existing Tensor::embedding_lookup ([vocab,hidden] x [batch,seq] -> [batch,seq,hidden]). - Attention weight lookup accepts both self_attn. (HF-LLaMA) and attention. prefixes; final layer norm accepts norm.weight / model.norm.weight / ln_f.weight aliases. - Integration fixture gains the final norm weight; the previously always-failing engine tests now pass (8/8 model_loading_test). End-to-end inference through the real engine now works for the first time — verified via model_zoo_demo producing real forward-pass outputs across all categories.

osobhandClaude Fable 5	733b02cd8b	feat(inference): concrete EAGLE draft model + real tokenizer at the serving boundary ... EAGLE (rtx-inference/src/eagle.rs, ~610 lines, mirrors medusa.rs conventions): EagleDraftHead autoregressive FFN with Concat/Add/ Attention feature fusion, EagleHeads draft model with draft/ draft_steps (per-step top-k for candidate trees) and teacher-forced training_loss; implements the speculative::EagleDraftModel trait so it plugs into the orchestration layer. 38 unit tests. Tokenizer (rtx-inference/src/tokenizer.rs): ServingTokenizer enum — Vocab (HuggingFace tokenizers, loadable from tokenizer.json) or ByteLevel fallback preserving previous behavior. rtx-serving-api's AppState and rtx-streaming's token generator now encode/decode through it (with_engine_and_tokenizer / set_tokenizer added; existing signatures unchanged). Also fixes two pre-existing compile errors in rtx-streaming (missing import, stray .await) that blocked its lib tests entirely. Tests: rtx-inference 328 pass, rtx-serving-api 193 pass, rtx-streaming 53 pass (2 pre-existing mock-server connection failures unrelated to these changes).

osobhandClaude Fable 5	0cbfc1a739	fix(tests): repair rtx-onnx-codegen build and all pre-existing test failures in rtx-serving-api and rtx-runtime ... - rtx-onnx-codegen: re-export AttributeValue from ir (private-module import broke the whole crate; remaining errors were knock-ons). - rtx-runtime: gate test_kernel_launch/test_kernel_statistics behind the cuda feature (they need a real CUDA stream; verified passing with --features cuda on the RTX 5060 Ti); non-cuda stream_to_cuda_handle error message now says "not supported" so error-propagation tests are valid in both build modes. - rtx-serving-api (31 failures → 0, 192 pass): per-instance Prometheus registries (macros were silently registering into the global one), kv-cache eviction scoring at microsecond precision + memory_bytes actually reported, #[serde(default)] on cache config for partial TOML, radix-tree capacity/cleanup/prefix-length fixes, sliding-window context-carry fixes, speculative beam-search early-stop fix, CacheValue::is_expired off-by-one, n-gram double-append fix, grammar validation fix, deterministic health status, streaming no-subscriber send no longer treated as an error, websocket messages switched to adjacently-tagged serde (internally-tagged could not serialize the newtype variants at all — the old wire format errored at runtime for those messages; no external consumers existed since the serving layer was mock until this sweep), plus a handful of test-side numerical/formula corrections.

osobhandClaude Fable 5	5f32165184	chore(sweep): delete 43 orphaned source files; document SYCL/demo/duplication status ... Deletions (all verified unreferenced by any mod/include/path declaration; git history preserves them): - rtx-transformers: entire orphaned curriculum/ split (mod.rs holds the real inline implementation), non-_simple graph variants, superseded simmim/jepa_integration files, layers/{sliding_window_attention, positional_encoding,ssm_state_cache_original}, lib_full/lib_minimal/ error_full/error_minimal, orphaned MoE impls (moe_layer, moe_integration). - rtx-distributed/parallel_old.rs; rtx-flash-attention/{core_full, lib_full}.rs; rtx-compress legacy_distillation + structured_pruner. - rtx-tensor/tensor_core.rs; rtx-runtime/{cuda_kernel_ops, cuda_backend_mock}.rs; rtx-memory/{gpu_pool_manager,allocator, pool_type}.rs; rtx-losses/{lib_minimal,lib_full}.rs. Docs honesty: - rtx-backend-sycl marked EXPERIMENTAL SKELETON in crate docs and CLAUDE.md backend table (all ops return NotImplemented). - docs/consolidation.md records canonical MoE (layers/mixture_of_experts) and flash-attention (rtx-flash-attention crate) implementations plus remaining duplicates to consolidate. - CLAUDE.md: meta-crate GPU features noted; simulation-only demos named; serving/streaming mock removal noted. Verified: cargo check --workspace clean (rtx-onnx-codegen pre-broken at HEAD, unrelated); lib tests pass for all touched crates (rtx-runtime's 4 failures pre-exist at HEAD).

osobhandClaude Fable 5	1e3c604896	feat(meta,jepa): expose GPU features through meta-crates; wire JEPA cluster plan and real shard loading ... Meta-crates (Phase 2): - rtx-core / rtx-training / rtx-inference-stack gain cuda and metal features threading into their sub-crates; GPU was previously unreachable through the user-facing bundles. - rtx-training restores rtx-distributed (the hpc-channels blocker is gone) so the advertised DistributedTransformerTrainer resolves; drops the unused rtx-runtime dep. - rtx-transformers drops unused rtx-backend/rtx-backend-cpu deps (stale comment referenced a teacher that never used them). Never-compiled CUDA paths fixed (surfaced by the new feature wiring, verified on RTX 5060 Ti / CUDA 13.1): - rtx-compress build.rs: missing Path/Command/fs imports. - rtx-flash-attention flash_decode_forward: reborrow &mut kernel args. - rtx-transformers: rope kernel include path, cudarc 0.18 Arc<CudaModule>, PushKernelArg imports in jepa_gpu, edition-2024 ref patterns. - rtx-memory: full cudarc 0.18 port (CudaContext, stream-based alloc, DevicePtr accessors, error enum formatting) across gpu_pinning, gpu_transfer, gpu_real, gpu_allocator/arena, gpu_tests. JEPA (Phase 3): - JepaRunConfig::apply_cluster_plan consumes ClusterTrainingPlan (batch size, TP/DP, world size, total steps) so jepa_cluster is no longer standalone dead config; ViTSizeStr::approx_params_m feeds JepaParallelConfig::for_model_and_cluster. - WebDatasetShard::load reads real .tar shards from disk via the existing parser (gzip rejected explicitly); to_in_memory documented as synthetic/test-only. - New image-decode feature actually defines the dep for the previously unreachable cfg(feature = "image-decode") JPEG/PNG decode path.

osobhandClaude Fable 5	64ade03ab9	fix(production): wire real inference path through engine, serving, and streaming ... - rtx-inference: sample_next_token now copies the actual logits from the forward pass (Tensor::to_vec, last-token slice) instead of sampling from a fabricated all-zero vector; request metrics report measured queue/processing times instead of hardcoded constants. - rtx-serving-api: depends on rtx-inference; /v1/completions dispatches to a shared InferenceEngine (byte-level tokenization until a real tokenizer is threaded through) and returns 503 when no engine is loaded instead of mock text. ServingServer::with_engine attaches one. - rtx-streaming: depends on rtx-inference; generate_tokens delegates to an attached backend engine and errors without one instead of emitting "token_N" placeholders; tokenization is byte-level, not position-mod. - speculative decoding: document the orchestration (speculative/) vs implementation (medusa.rs/lookahead.rs) layering; CLAUDE.md no longer claims a standalone rtx-speculative-decoding crate.

osobhandClaude Sonnet 5	522400a72b	fix(deps): bump candle-core/nn/transformers 0.8->0.11 for CUDA 13.1 build ... candle-kernels 0.9.2/0.8.4's compatibility.cuh has a buggy CUDA-version guard ((MAJOR<12 || MINOR<2) && ARCH<750) that misfires on CUDA 13.1, redefining __hmax_nan/__hmin_nan/atomicAdd that 13.1 already provides natively. Fixed upstream in candle-kernels 0.11.0 (pure ARCH<800 gate), so bump the workspace-wide candle pin to pull it in. rtx-csm stays on candle 0.9.1 directly (not the workspace pin) since it shares Tensor types with moshi 0.6.4, which itself pins candle-core 0.9.1 - both candle trees now build cleanly side by side. Also fixes two latent compile issues surfaced by actually building the cuda feature: DType is #[non_exhaustive] with new I16/I32/float8 variants (rtx-candle), and a missing HashMap import gated behind the candle feature (rtx-inference).

osobhandClaude Opus 4.8	b861b3bb2e	fix(rtx-science): drop unused ndarray-linalg dep ... Declared but never referenced; forced openblas-build (no good Apple-Silicon backend) and broke the macOS build. Co-Authored-By: Claude Opus 4.8 <[email protected]>	2026-06-27 10:59:42 -07:00
osobhandClaude Opus 4.8	71ffbf364d	fix(deps): vendor + patch pathfinder_simd 0.5.6 for Apple Silicon nightly ... arm/mod.rs used simd_minimum_number_nsz/simd_maximum_number_nsz intrinsics absent on nightly-2025-10-25; swapped for simd_fmin/simd_fmax (same NaN semantics).

osobhandClaude Opus 4.8	70da8215a2	fix(demos): drop openblas/metal from default features (CPU-only default, backends opt-in) ... demos/{rtx-mre,rtx-bioheat,rtx-hemodynamics} defaulted to [cpu, openblas, metal], which broke cargo build --workspace on BOTH platforms: - openblas: no system lib on macOS + buggy on arm64 (sgemm returns zeros, per rtx-tensor note) - metal: objc2 deps are macOS-only, so enabling it on Linux fails to resolve Default to cpu only; openblas/metal/accelerate remain opt-in per platform.

osobhandClaude Opus 4.8	63776aa0f2	fix(rtx-backend): gate CUDA dev-dep to x86_64-linux so cargo test works on macOS ... rtx-backend's only build-graph CUDA pull was a [dev-dependencies] entry (rtx-backend-cuda with features=[cuda]) compiled unconditionally, so cargo test --workspace failed on macOS/non-CUDA hosts trying to build cudarc. Gate it to x86_64 Linux (where the CUDA toolkit lives); cargo build was unaffected. Also drop the no-op cuda from rtx-nlg default features (empty placeholder that misleadingly implied CUDA-by-default). Audit: 121/126 workspace crates already gate CUDA correctly (optional + non-default). Co-Authored-By: Claude Opus 4.8 <[email protected]>	2026-06-27 09:07:14 -07:00

Claude CodeandClaude Opus 4.8	df6ce1ce22	feat(rtx-nn): genericize the layer library over B::FloatElem (f64-capable) ... Phase 4b of the rustytorch f32→f64 plan. Relaxed ~36 `impl<B: Backend<FloatElem = f32>>` blocks across 7 layer files to `impl<B: Backend>` over B::FloatElem: normalization (LayerNorm/RMSNorm), activation (LeakyReLU/ELU), dropout (1d/2d/3d), embedding, attention (MultiHeadAttention), transformer (MLP/Block/Encoder), conv (Conv1d/2d). Config scalars stay f32 and convert via B::FloatElem::from_f32; the layers delegate to the already-generic GenericTensor ops. f32 numerics byte-identical. The whole common rtx-nn layer library now runs on CpuBackendF64. Validated: 334 f32 lib tests (no regression) + 2 capstone + 3 new f64 layer smoke tests (layer_norm/conv2d/attention on CpuBackendF64) pass; QPUDIDP surrogate still compiles; clippy clean. Remaining f32-gated: batch_norm (GenericBatchNorm1d/2d/GroupNorm) — its manual mean/variance arithmetic needs a `where B::FloatElem: num_traits::Float` bound; focused follow-on.

Claude CodeandClaude Opus 4.8	c28a848250	feat(rtx-nn): f64-capable GenericLinear + f64 MLP gradient-precision capstone ... Phase 4/5 of the rustytorch f32→f64 plan. GenericLinear's 3 `impl<B: Backend<FloatElem = f32>>` blocks relaxed to `impl<B: Backend>` (from_weights takes &[B::FloatElem]; Xavier scale via B::FloatElem::from_f64), so a Linear→ReLU→Linear MLP runs end-to-end on CpuBackendF64. f32 backward-compat holds via B::FloatElem = f32. Capstone (tests/f64_mlp_precision.rs): a 4→8→1 MLP gradient checked vs central finite differences — f64 err 6.99e-12 (≤1e-9) vs f32 err 1.01e-2, i.e. f64 ~1.45e9× more accurate. This is the quantum-precision-gradient win that motivated the migration. Validated: rtx-nn 334 f32 lib tests + 2 new f64 capstone tests pass; rtx-autograd builds + tests pass; **QPUDIDP qpu-didp-surrogate compiles + 15 tests pass** (uses GenericLinear). clippy clean. Scope note: rtx-autograd's reverse-mode tape stores f32 concretely (backward()->HashMap<_,Vec<f32>>) — making it f64 is a deep tape re-architecture, not a constraint relaxation, so it's a documented follow-on (no current consumer uses it; QPUDIDP hand-rolls f64 backprop). Other rtx-nn layers (conv/transformer/attention/...) remain f32-gated — same mechanical relaxation, follow-on.

Claude CodeandClaude Opus 4.8	a25f24494c	feat(rtx-tensor): genericize GenericTensor over B::FloatElem (f64-capable) ... Phase 2 of the rustytorch f32→f64 plan. All 6 `impl<B: Backend<FloatElem = f32>>` blocks on GenericTensor relaxed to `impl<B: Backend>`, with concrete f32 → B::FloatElem (full/from_slice/to_vec/add_scalar/mul_scalar/pow/clamp/leaky_relu/ elu/layer_norm/rms_norm). The genericization was fully clean — every Backend trait scalar param was already Self::FloatElem, so no methods had to stay f32-gated. GenericTensor now works with CpuBackendF64 as well as CpuBackend. Backward-compat holds via B::FloatElem = f32 for CpuBackend: to_vec() still returns Vec<f32>, from_slice still takes &[f32]. Validated: 706 rtx-tensor tests pass (704 f32 + 2 new f64); the f64 test proves 1+2^-30 survives through from_slice/matmul/to_vec (f32 rounds to 1.0). rtx-nn builds; **QPUDIDP's qpu-didp-surrogate (external, ~125 f32 sites) still compiles**. clippy clean.
