ParFiSys: A Parallel File System for MPP

摘要

The continuous MPP computing power growth has not been corresponded with an equivalent improvement in I/O bandwidth. As a result, computation, memory and I/O are more unbalanced every year, with more MPP applications being I/O bounded. This paper gives an overview of ParFiSys, a parallel file system developed at the UPM to provide I/O services to the GPMIMD machine, an MPP developed within an ESPRIT project. The main goals of ParFiSys are to provide I/O services to scientific applications requiring high I/O bandwidth, to minimize application porting effort and to exploit the parallelism of generic message-passing multicomputers.
