From 116f04968beae706e0cedc484705258b86f34848 Mon Sep 17 00:00:00 2001 From: jgrusewski Date: Thu, 26 Mar 2026 00:42:39 +0100 Subject: [PATCH] =?UTF-8?q?feat:=20major=20kernel=20modules=20load=20from?= =?UTF-8?q?=20precompiled=20cubins=20=E2=80=94=20zero=20runtime=20nvcc?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace OnceLock + compile_ptx_for_device() with include_bytes! + Ptx::from_binary() in 13 Rust files: - gpu_action_selector.rs (epsilon_greedy) - gpu_statistics.rs (batch_statistics) - gpu_training_guard.rs (training_guard) - signal_adapter.rs (signal_adapter) - gpu_monitoring.rs (monitoring_reduce) - gpu_curiosity_trainer.rs (curiosity_training) - gpu_attention.rs (attention forward + backward) - gpu_backtest_evaluator.rs (env, metrics, gather, ppo, supervised, dqn) - gpu_experience_collector.rs (experience, nstep, her_episode) - gpu_her.rs (her_episode, her_relabel) - gpu_iql_trainer.rs (iql_value) - gpu_iqn_head.rs (iqn_dual_head) - gpu_ppo_collector.rs (ppo_experience) Remaining runtime compilation: inline utility kernels in gpu_dqn_trainer.rs (grad_norm, adam, ema, saxpy, zero, etc.) — small kernels that compile in ms. 883/887 tests pass (4 pre-existing failures in data_loader/hyperopt).
