vLLM now haspipeline parallelism! (#4412,#5408,#6115,#6120). You can now run the API server with--pipeline-parallel-size. This feature is in early stage, please let us know your feedback. 2. 配置 ParallelConfig: pipeline_parallel_size: Number of pipeline parallel groups. 参数验证: Engin...
Pipeline parallelism 是 transformers 库在 v4.6 版本中引入的一种新的并行处理技术,它允许用户在多个处理器(如 CPU、GPU)上并行执行不同的步骤,例如 tokenization、padding、model inference 等。通过设置--pipeline-parallel-size参数,你可以指定 pipeline parallelism 的规模。这个参数的值应该等于你想要并行运行的处理...
Open [Bug][Ray]: Pipeline parallelism fails on the same host#14093 Description bkutasi opened on Mar 2, 2025· edited by bkutasi Edits Your current environment Using the 0.7.3 ghcr.io/sasha0552/vllm:v0.7.3 (pascal docker from pascal-pkgs-ci) and the same version directly from vllm ...
Hope you're all doing great! I‘m focusing on pipeline parallel inference and I hope it can be support on vllm. I noticed that pipeline parallelism was on the old roadmap(#244) , but it's not on the new roadmap(#2681). Just curious, was there a specific reason you guys decided ...

支持k8s 集群部署,通过流水线并行(Pipeline Parallelism)扩展至多台服务器。 五、选型建议 1. 选择 SGLang 的场景 需要处理复杂的多轮交互任务(如对话系统、规划代理)。 要求生成结构化输出(如 API 调用结果需严格遵循 JSON 格式)。 需深度定制生成逻辑或优化缓存复用。
