摘　　要：复杂的大规模并行计算机系统需要能客观反映系统性能的测评方法,单个指标难以全面评价系统的性能特点。从用户需求出发,给出了大规模并行计算机系统用户适用性概念,利用适用性概念,建立了大规模系统性能测评体系,包括总体适用性、分项适用性、适用性概念、准则和Benchmark程序。整个测评体系尽量消除主观因素,做到客观定量,利用测评体系,借助性能分析数据获取工具,在得到量化的分项适用性的基础上,通过权重公式可以求出总体适用性,根据总体适用性的大小来判断不同大规模计算机系统是否满足用户的需求。The complexity of modern massively parallel computer systems requires sophisticated method to facilitate the evaluation of system performance, and it is difficult to measure all the character- istics of systems using a single metric. The concept of applicability is given from the demand of users for supercomputers. Based on the applicability concept, we present a performance evaluation methodology for massively parallel computer systems. The methodology, including total applicability, subentry appli- cability, the concepts of subentry, metrics and benchmarks, can avoid the personal factors and obtains the impersonality results for systems perfm＇manee. After collecting data using performance analysis tools, the data can be used to get the subentry applicability. Then the total applicability can be calculat- ed by the weight equation. Based on the total applicability, one can evaluate whether the massively par- allel computer systems satisfy the demand of user or not.
