Development of Comprehensive Parallel I/O Benchmarking Tool for HPC Cluster File Systems
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
High Performance Computing Clusters uses parallel file systems such as Lustre, GlusterFS for better I/O throughput with multiple clients. These file systems are implemented over high speed interconnects like 10G, Quadrics, Myinet and Infiniband. Parallel scientific applications require high performance I/O support from underlying file systems. The objective of this work is to evaluate and analyze performance of parallel file systems in HPC cluster with different configuration parameters with development of a comprehensive bench-marking tool. The developed tool measures the performance of different data I/O and meta-data operations under various workloads. This paper briefly describes various cluster file systems, parallel I/O approaches and different Message Passing Interface (MPI) implementations supporting MPI-IO and throughput results for different I/O scenarios.
