Abstract

The UXP/V HPF compiler, that has been developed for the VPP series vector-parallel supercomputers, extracts the highest performance from the hardware. However, it is getting difficult for developers to concentrate on a specific hardware. This paper describes a method of developing an HPF compiler for multiple platforms without losing performance. Advantage is taken of existing technology. The code generator and runtime system of VPP Fortran are reused for high-end computers; MPI is employed for general distributed environments, such as a PC cluster. Following a performance estimation on different systems, we discuss effectiveness of the method and open issues.
