CHIME system boosts LLM long-context attention inference with DIMM-PIM

Researchers have developed CHIME, a novel system designed to improve the efficiency of long-context attention operations in large language models. CHIME integrates DIMM-PIM technology, which offers a balance of scalable capacity and bandwidth, addressing limitations in previous Attention-FC Disaggregated (AFD) systems. The system employs advanced techniques like bubble-free pipelining and hybrid-grained re-layout to manage distributed DRAM chips and optimize attention computation. Evaluations indicate that CHIME can achieve up to a 5.15x speedup compared to existing HBM-PIM solutions. AI

IMPACT Enhances LLM inference efficiency, potentially reducing costs and latency for long-context applications.

    CHIME: A Case for Efficient Long-Context Attention-FC Disaggregated Inference with DIMM-PIM

    arXiv:2504.17584v2 Announce Type: replace-cross Abstract: Attention-FC Disaggregated (AFD) LLM inference systems offload memory-bound Attention operations to memory-rich accelerators (e.g., CPUs, HBM-PIM) while retaining compute-bound Fully-Connected (FC) operations on GPUs. In t…
