| 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。 |

| Abstract: |
| Load balance is an important concept in the parallel processing. Whether the work load carried by each processor participating in a program execution is balanced or not directly influences the parallel performance of the program. This paper discusses optimization of the load balance in the loop order parallelization and presentes an optimization strategy as well as its practical algorithm. |
| Keywords: program parallelization,load level,data distribution,loop iteration distribution. program parallel performance |
