A new system optimization technique called LayerSplit has been developed to address performance bottlenecks in long-context Coding Agent Serving tasks. This method tackles the Prefill stage, which has become a major performance factor. LayerSplit reduces memory and bandwidth pressure by having each GPU store only a portion of the KV Cache, significantly lowering individual GPU memory usage. Before Attention computation, the relevant KV Cache layers are broadcast to other ranks, and a mechanism is designed to overlap KV Cache broadcasting with indexer computation to minimize communication overhead.
