- 发生了什么
- vLLM released Decode Context Parallelism improvements for long-context inference, splitting KV cache across GPUs by sequence position instead of attention heads.
- 为何重要
- Engineers serving long-context agentic workloads on multi-GPU systems need this to sustain higher request concurrency without memory replication bottlenecks.
- 注意
- DCP requires high-bandwidth GPU interconnects and works differently for MLA versus GQA models, with specific tensor-parallel and DCP size constraints for each.
