jgrusewski	316233372a	refactor(bf16): CudaSlice::raw_ptr() — eliminate ALL device_ptr() calls ... Added raw_ptr() method to vendor/cudarc CudaSlice — returns device address without event tracking (no SyncOnDrop guard leak). Replaced ALL 119 raw_device_ptr() wrapper calls with .raw_ptr(). Deleted raw_device_ptr, raw_device_ptr_i32, raw_device_ptr_u32 wrappers. Added forward_online_raw / forward_target_raw for graph-safe forward. All CachedPtrs used in graph-captured code paths. Smoke test: model trains (Sharpe improves -24→+1), but Q-stats readback still returns 1e30. The issue is NOT device_ptr event tracking — deeper investigation needed.

jgrusewski	07d0e60fe4	feat(bf16): remove nvrtc from entire workspace + wire ml-core precompiled cubins ... - Fork cudarc locally (vendor/cudarc): add CudaContext::load_cubin() that calls cuModuleLoadData directly — zero nvrtc dependency - Remove "nvrtc" feature from ml-core, ml-dqn, ml-ppo Cargo.toml - Replace all 89 Ptx::from_binary + load_module calls with load_cubin - ml-core cuda_autograd: wire 9 stub constructors to precompiled cubins (activation, elementwise, linear, loss, reduction, dropout, layer_norm, optimizer) - ml-core build.rs: compile 8 BF16-native CUDA kernels via nvcc - cubin_loader.rs: thin wrapper around CudaContext::load_cubin() - Fix size_of::<f32> in gpu_tensor.rs, stream_ops.rs, layer_norm.rs - Fix test data: Vec<f32> → Vec<half::bf16> for memcpy_htod - Stub ml-ppo/ml-dqn runtime compile_ptx calls (dead code) - backtest_metrics_kernel.cu: full native BF16 rewrite (no float) - backtest_env_kernel.cu: shared memory → __nv_bfloat16 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-28 10:11:46 +01:00
