Expectations of the High Performance Computing Cluster File System Selection

When constructing a high-performance computing cluster, one of the most pressing issues is ensuring efficient organization of the external storage systems. Such systems consist of both hardware and software components. The software component is a parallel file system, and consists of server and client parts. The article explores the principles of operating parallel file systems: mechanisms of data sharing between clients; metadata and data maintenance methods; as well as aspects of selecting a parallel file system for a high performance cluster computing cluster. We have had the opportunity to test some solutions on the large supercomputers of Joint Supercomputer Center of the Russian Academy of Sciences (JSCC RAS) and develop a basic model for file data flow in HPC cluster.
