Abstract: High Performance Fortran (HPF) is the first widely supported,
efficient, and portable parallel programming language for shared and
distributed memory systems. HPF is realized through a set of
directive-based extensions to Fortran 90. It enables application
developers and Fortran end-users to write compact, portable, and efficient
software that will compile and execute on workstations, shared memory servers,
clusters, traditional supercomputers, or massively parallel
processors. This article describes a production-quality HPF compiler
for a set of parallel machines. Compilation techniques such as data
and computation distribution, communication generation, run-time
support, and optimization issues are elaborated as the basis for an HPF
compiler implementation on distributed memory machines. The
performance of this compiler on benchmark programs demonstrates that high
efficiency can be achieved executing HPF code on parallel
architectures.
