Distributed memory architectures call for I/O hardware and software beyond those of conventional scalar systems. \par This paper introduces the MasPar I/O system, designed to provide balanced and and scalable data-parallel Unix I/O. The architecture and implementation of the I/O hardware and software are described. Key elements include parallel access to conventional Unix file descriptors and a self-routing multistage network coupled with a buffer memory for flexible parallel I/O transfers. Performance measurements are presented for parallel Unix I/O with a scalable RAID disk array, a RAM disk, and a HIPPI interconnect.}, comment = {This provides the definitive reference for the Maspar parallel-I/O architecture and file system. This paper includes a brief discussion of the interface and performance results. Also includes some HIPPI interface performance results. This paper is the conference version of nickolls:dpio, so cite this one.} }
