摘　　要：目前在高等学校和科研机构中对于高性能计算的需求很大,而商业的超级计算机性能虽高但价格昂贵,同时这些单位又都拥有大量普通的PC机和网络设备。为了利用现有硬件资源获取高性能计算能力,文中研究了在PC机和Linux环境下构建基于MPICH2的高性能计算集群系统的方法,搭建了一个拥有16个节点的系统并利用高性能Linpack基准测试方法进行了性能测试。测试结果表明,这种构建高性能计算集群系统的方法切实可行,是低成本获取高性能计算能力的良好途径。High performance computation is in great demand in universities and research institutions these days. The performance of commercial supercomputer is very high, but it is very expensive. At the same time, there are a mass of ordinary PC and network equipment in university and research institutions. In order to take advantage of existing hardware resources access to high - performs ace computing capabilities, researched the method in building up a high performance computer cluster system which was based on MPICH2 in Linux operating system on PCs and built a system which has sixteen nodes. Meanwhile HPL testing was applied to measure system performance And the testing results made it clear that this method was not only very useful in building up cluster systems but also cost- effective.
