高性能计算集群的 Linpack测试及其在大数据中的应用
Linpack Test of High Performance Computing Cluster and Its Application in Big Data
摘要
Abstract
High performance computing cluster for efficient parallel computing is of very high cost performance and good scalabili -ty.How to test and evaluate the cluster system performance becomes a key problem .In this paper, we made a Linpack test based on high performance computing cluster of 6 nodes .Different matrix scale N , computational nodes , block size NB of matrix , pro-cessor grid topology and network communication were tested .Computing performance to PC and cluster were compared and cluster performance was tested .The results show that:the cluster parallel computing performance is good and is of strong scalability , but the hardware communication ability should be further improved .The cluster is applied into the computing of the actual seismic big data.It is known that the parallel computing performance of the cluster has been improved greatly .关键词
