摘要
负载平衡是并行处理中的一个重要概念。参与一个程序执行的各处理机所承担的工作量是否均衡直接影响该程序的并行性能。本文对面向MPP系统程序循环级并行化中负载平衡的优化进行了探讨，提出了优化策略及其实施算法。
Load balance is an important concept in the parallel processing. Whether thework load carried by each processor participating in a program execution is balanced or notdirectly influences the parallel performance of the program. This paper discusses optimiza-tion of the load balance in the loop order parallelization and presentes an optimization strate-gy as well as its practical algorithm.
