Prefetch Distance Control Strategy Based on Cache Behavior in Threaded Prefetching

  • 摘要: 針對目前大多數(shù)面向指針應用程序的線程數(shù)據預取方法在預取距離控制方面的不足,該文提出一種基于緩存行為特征的數(shù)據預取距離控制策略。該策略利用指針應用程序執(zhí)行時的數(shù)據緩存特征構建預取距離控制模型,以避免共享緩存污染,降低系統(tǒng)資源競爭,并通過忽略對部分非循環(huán)依賴數(shù)據預取平衡幫助線程與主線程間的執(zhí)行任務,提高線程數(shù)據預取的時效性。實驗結果表明,通過該策略控制線程數(shù)據預取距離能進一步提高線程預取性能。
