Abstract

OpenMP is a directive-oriented paradigm for parallel programming applicable to shared memory parallel computers. On the other hand, High Performance Fortron (HPF) is also a directive-oriented paradigm but for distributed memory machines. Thus, it could be very interesting to compare their programming applicability and parallel performances. We have converted four SPEC OMP 2001 benchmark programs, which are written with OpenMP and designed to evaluate the performance of shared memory parallel computers, into HPF, and evaluated parallel performances. We also point out problems that we had faced during conversion, and discuss solutions for them. Finally, we have improved the HPF performance by modifying the original source code. We could get good performance with HPF quite similar to OpenMP with SWIM, and moderate performance with APSI.
