AI Overview
TL;DR: Long agentic contexts push GLM-5.3 against two limits on H200s: KV cache memory and prefill speed. We address both on 16 H200s, split into one prefill node and one decode node: Prefill Context Parallelism (PCP) splits each prompt across GPUs by token instead of by...
Curator's Note
原文提出了针对 GLM-5.3 在 H200 上的优化方法，包括 PCP、DCP 和混合 HiSparse，读者可以了解这些优化如何提升长上下文处理能力。
