公平性考虑的短作业优先内存调度策略
Fairness-considered Shortest Job First Strategy for Memory Scheduling
摘要
Abstract
It is unfair, ineffective to access shared memory for multi-thread on the chip of multi-core. This paper proposes fairness-aware shortest job first scheduling which sets request for the maximun waiting time to guarantee fairness, uses shortest job first priority to cut down the average waiting time, pays attention to parallelism of threads to solve above problems. Experimental result shows that this method improves IPC performance in multi-thread visit, and the highest performance improvement can reach 43%.关键词
