vllm-qfn source snapshot

Public source snapshot of the patched vLLM engine used for the SuperPUPS/Qwen3.8-Flash-Next-* checkpoints.

Identity

  • Engine name: vllm-qfn
  • Authoritative snapshot: branch feature/qsa-int8-kv, commit e12683d245
  • Includes: PLE mmap offload, CUTLASS FP8 guard, TurboQuant K8V4 wiring, and int8_per_token_head KV-cache support
  • Reported vllm --version: 0.28.1rc1.dev78+gb009560d6.d20260923.cu132

The reported version string reflects the underlying base and does not advance with every local commit. Use the snapshot commit as the authoritative identifier.

Files

  • vllm-qfn-e12683d245.tar.gz — sanitized source snapshot
  • qfn-build.diff — patch delta for reference
  • CHECKSUMS.sha256
  • SANITIZE_NOTE.md — excluded paths and secret-scan procedure

Required runtime variables

For the Qwen3.8-Flash-Next checkpoints with the 102.4 GB PLE table:

export VLLM_PLE_CPU_OFFLOAD=1
export VLLM_PLE_MMAP_TABLE=1

VLLM_PLE_MMAP_TABLE=1 is required on 64–128 GB host RAM systems. Without it, upstream-style pinned-table paths can consume ~117 GB+ RSS.

Reference host note

zram-based swap was enabled on the test host. This is host tuning only. It is not required by the model or by the VLLM_PLE_MMAP_TABLE=1 path, and it is not a workaround for upstream vLLM 0.31 pinned-table OOM.
