Utilizing Chiplet-Locality For Efficient Memory Mapping In MCM GPUs (ETRI, Sungkyunkwan Univ.)

Researchers from ETRI and Sungkyunkwan University published a technical paper on leveraging chiplet-locality for efficient memory mapping in multi-chip module GPUs. The study explores how page size in memory mapping impacts memory system non-uniformity in MCM GPUs. They introduce CLAP, a method to determine the suitable page size for each application based on chiplet-locality patterns. CLAP optimizes data placement within chiplets, improving performance by up to 19.2% compared to previous paging schemes. The paper was presented at the 58th IEEE/ACM International Symposium on Microarchitecture.
