Fortran 90D/HPF Compiler for Distributed Memory MIMD Computers: Design, Implementation, and Performance Results

Fortran 90D/HPF is a data parallel language with special directives to enable users to specify data alignment and distributions. This paper describes the design and implementation of a Fortran90D/HPF compiler. Techniques for data and computation partitioning, communication detection and generation, and the run-time support for the compiler are discussed. Finally, initial performance results for the compiler are presented which show that the code produced by the compiler is portable, yet efficient. We believe that the methodology to process data distribution, computation partitioning, communication system design and the overall compiler design can be used by the implementors of HPF compilers.
