From 5b9ef3fbe1e960c648806f28b9d9d3400a0b22c9 Mon Sep 17 00:00:00 2001 From: jgrusewski Date: Sun, 22 Mar 2026 15:46:55 +0100 Subject: [PATCH] =?UTF-8?q?fix:=203=20H100=20GPU=20test=20failures=20?= =?UTF-8?q?=E2=80=94=20consistent=20network=20dims=20+=20phase=20bounds?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit dqn-smoke: hardcoded (256,256,128,128) network dims → (64,64,32,32). With 256-wide layers, NoisyNet noise (sigma=2.0) can't overcome Q-value gaps even at high sigma. Smaller dims ensure noise dominates. dqn-early-stop: apply dqn-smoketest.toml profile for consistent hidden_dim across RTX 3050 and H100. Without it, H100 gpu profile sets hidden_dim=256 which changes gradient dynamics. dqn-collapse: v_range bound assertion 25.0 → 20.0. Phase Fast (default) fixes v_range to 20.0 from [phase_fast] TOML. The old assertion expected the unfixed (10.0, 50.0) range.
