From 69cce1b28e0c29dd1620777e30ee12d73268e1db Mon Sep 17 00:00:00 2001 From: amy-why-3459 Date: Sat, 24 Oct 2026 01:54:55 +0800 Subject: [PATCH 1/3] [Perf][Ascend] Replay Drama 3 decode steps as FULL graphs Stage 0 of Drama 3 samples one whole audio frame per stream per step: 40 backbone layers (Qwen3.5 MoE) plus 13 codebook-tower layers of small kernels, and the sampled result feeds the next step's embedding. Decode is the steady state of a stream, so per-kernel launch cost dominates the arithmetic, but the NPU override only asked for PIECEWISE capture, which keeps the pure decode path in eager execution. Ask for FULL_AND_PIECEWISE and capture sizes up to max_num_seqs. Mixed steps (a new request's prompt rows) still replay the piecewise backbone graphs; decode steps replay one graph for their batch size. Measured on 2x910B1, TP2 + expert parallel, 64 streams, Seed-TTS-Eval en with a fixed pre-encoded reference: C1 RTF mean 1.24 -> 0.95 (-23%) C1 frames/s 17.3 -> 22.9 (+32%) C1 TTFA p50 0.91 s -> 0.78 s 16 streams reach 133 frames/s and 64 streams 305 frames/s on the same build, so the capture sizes below max_num_seqs also cover the batched decode shapes. A test pins the override: a PIECEWISE-only NPU config silently reverts decode to eager.
