Skill instructions
CPU C++ Kernels for x86 Processors This skill provides patterns and guidance for developing optimized C++ kernels targeting x86 CPUs (Intel Xeon and compatible processors) with AVX2 and AVX512 intrinsics. Kernels are compiled via kernel-builder and distributed through the Hugging Face kernels ecosystem. Who runs these commands? You, the agent — not a human. This is an autonomous loop: you write/edit the C++ kernel, build it, then run the scripts below as tools (via Bash) to check correctness, benchmark, and profile. You read each result, record it with trialmanager.py, decide the next change from the Phase 2 decision tree, and repeat until you hit earlystopspeedup or run all maxtrials. Key Concepts (read before the Quick Start) The commands use a few names that mean different things. They are not interchangeable: | Name (example) | What it is | Used by | |----------------|-----------|---------| | baseline.py | The PyTorch reference implementation you optimize against. It is the ground
