The VPP500 system is a commercial, distributed memory, parallel computer system based on vector parallel architecture. The software of the VPP500 system is described here. The os is UNIX-based, enhanced with distributedparallel features. A system that is easy to use and has high performance requires a (1) realized one-system image;(2) pursued ultrahigh performance;and (3) enhanced operation of the system. To satisfy two fundamental requirements of a language processor system, (1) effective use of the existing program assets and (2) extraction of potential performance of hardware system, we have implemented VPP Fortran (the standard FORTRAN77 enhanced with the features of parallel processing). The various data on VPP Fortran show that the VPP500 system, which consists of hardware, os and language processor system, has both high performance and high efficiency.
