vllm-cpu-base-avx2

amd64 vLLM vllm-openai CPU image built with VLLM_CPU_AVX2=true for hosts that have AVX2 but not AVX-512.

Hub vllm/vllm-openai-cpu amd64 targets AVX-512; benchmark-vllm-cpu-avx2 uses this base.

Published as ghcr.io/sparecores/vllm-cpu-base-avx2:main (amd64 only). The folder's prepare.sh hook clones the pinned source, sizes compile parallelism on physical RAM, and patches docker/Dockerfile.cpu; the build framework builds it on linux/amd64. Version pin: VLLM_VERSION.

CI exports layer cache to GitHub Actions cache (type=gha, scope vllm-cpu-base-avx2-amd64-v{VLLM_VERSION}) and GHCR (buildcache-amd64). The first successful build populates both; reruns on the same runner class should restore GHA cache quickly. If buildcache-amd64 does not exist yet, registry import is skipped and the build still runs (registry cache docs).
