This paper discusses the design and implementation of a cluster file system, called PVFS-PM, on the SCore cluster system software. This is the first attempt to implement a cluster file system on the SCore system. It is based on the PVFS cluster file system but replaces TCP with the PMv2 communication library supported by SCore to provide a scalable, high-performance cluster file system. PVFS-PM improves the performance by factors of 1.07 and 1.93 for writing and reading, respectively, with 8 I/O nodes, compared with the original PVFS on TCP on a Gigabit Ethernet-connected SCore cluster.
