Abstract
This paper tests the performance of NFS and Lustre file system in the large scale distributed computing environment on high performance computing platform. According to the results, the IO bottleneck is known in this high performance computing platform and an advice is given to improve the IO performance to solve the bottleneck problem. Then this paper tests how the local cache, file's size and transferSize affect the parallel filesystems' IO performance, and proposes how to deploy the parallel applications and write the parallel programs efficiently to improve the IO performance.关键词
