摘　　要：HPL是LinpackBenchmark的并行版本,是高性能并行计算机系统性能评测的标准测试程序,对公正、全面、系统地评价机器的浮点性能具有重要意义。基于一个8节点的PC集群,测试了该集群的Linpack性能。根据实验数据,得出了集群性能与集群节点数之间近似线性关系的结论,并给出了处理器维数、问题规模与系统性能之间的关系。HPL is the parallel version of Linpack Benchmark,and also the standard testing program for high performance pa-(rallel) computer systems.It plays an important role in fairly,completely and systematically evaluating a machine's floating-point performance.We perform HPL test for a PC cluster with 8 nodes.We analyze the obtained data and reach the conclusion that the performance of the cluster can scale near linearly with the number of cluster nodes.We also derive the relations among processor grid dimension,problem size and HPL performance.
