software prefetching for Indirect Memory Accesses: A Microarchitectural Perspective
收藏 引用
ACM TRANSACTIONS ON COMPUTER SYSTEMS 2019年 第3期36卷 8-8页
作者: Ainsworth, Sam Jones, Timothy M. Univ Cambridge Cambridge England Dept Comp Sci & Technol William Gates Bldg15 JJ Thomson Ave Cambridge CB3 0FD England
Many modern data processing and HPC workloads are heavily memory-latency bound. A tempting proposition to solve this is software prefetching, where special non-blocking loads are used to bring data into the cache hier... 详细信息
