feat(parakeet-cpp): enable GGML_CUDA_GRAPHS in the cublas build#10273
Merged
Conversation
ggml leaves GGML_CUDA_GRAPHS off by default. Passing -DGGML_CUDA_GRAPHS=ON for cublas builds lets the CUDA backend capture and replay the compute graph for a small free speedup (about 1% measured on a GB10, never negative). It is not gated by parakeet.cpp's CMake options, so it passes straight through to ggml. Assisted-by: Claude Opus 4.8 <noreply@anthropic.com>

What
Pass
-DGGML_CUDA_GRAPHS=ONalongside-DPARAKEET_GGML_CUDA=ONin the parakeet-cpp backend'scublasbuild.Why
ggml leaves
GGML_CUDA_GRAPHSoff by default. With it on, the CUDA backend captures and replays the compute graph for a small but free speedup. Measured on a GB10 (interleaved, best-of, same 180s clip):Never negative across runs. It is not gated by parakeet.cpp's CMake options, so it passes straight through to ggml and takes effect regardless of the pinned parakeet.cpp commit.
Notes
GGML_CUDA_DISABLE_GRAPHS=1still works for A/B testing.🤖 Generated with Claude Code
