High Performance Fortran is a portable, high-level extension of Fortran for creating data parallel applications on non-uniform memory access machines. Recently, a set of language extensions to Fortran and C based upon a fork-join model of parallel execution was proposed; called OpenMP, it aims to provide a portable shared memory programming interface for shared memory and low latency systems. Both paradigms offer useful features for programming high performance computing systems configured with a mixture of shared and distributed memory. In this paper, we consider how these programming models may be combined to write programs which exploit the full capabilities of such systems.
