arXiv Paper Proposes Partitioned KVCache Format to Balance CPU-GPU Load in MoE Inference
A new arXiv preprint describes a key-value cache layout that is physically split so work can be divided between CPU and GPU during long-context inference with Mixture-of-Experts models. The approach targets the case where single-GPU memory is insufficient and the KV cache must spill into host memory, where the stored data either feeds attention on the GPU or supports computation on the CPU. The proposed format is designed to keep those two uses balanced rather than treating the spilled cache as a single monolithic block.
