V100 users get a forked SGLang stack for Qwen and Laguna
A Reddit post describes a fork of SGLang customized for older V100 GPUs. The author says they:
- implemented TeiLang FlashAttention for V100,
- used open-source Marlin-V100,
- enabled ungated FlashInfer for sm70,
- made DFlash work for Qwen3.5 / Qwen3.6, and
- added Laguna S2.1 support.
They also report trying, but failing, to make DFlash work for Laguna so far. On their 4×V100 32GB NVLink setup, they claim roughly 4000–6000 pp and about 100 tokens/sec for Qwen.
The post includes a repo link, a TileLang FA repo, Marlin-V100, and says there is a Docker image so users do not need to spend a long time building from source.
