Abstract
One of the most intellectual steps in compiling for distributed memory parallel machines is to determine a suitable data partitioning scheme for a particular program. Most of the parallelizing compilers for these machines provide no or little support to the user in this difficult task. We have developed DPART, an automatic data partitioning system for Fortran 77 procedures. This paper describes the partitioning strategics of alignment, distribution, and processor layout in DPART. Finally we present experimental results for TRED2, DGEFA, and JACOBI procedures to demonstrate the effectiveness of this system.
