Performance Evaluation of A Infiniband-based Lustre Parallel File System

As one of the most widely used parallel file systems, Lustre plays an important role in High Performance Computing (HPC). In this paper, an infiniband-based Lustre parallel file system is built firstly. And then a series of experiments are executed to evaluate the performance of luster with infiniaband. Some parameters have great influence on the result, such as size record, client count, stripe count and stripe size. Experimental results indicate that the higher is the speed of network the higher aggregation bandwidth luster could provide. Moreover, Client count and stripe count have more impact on the performance of luster than the record size and stripe size. Appropriate record size and stripe size could improve the performance a little, but not significantly.
