Abstract

An important question of concern for both compiler writers and computational scientists is: How does the existing compiler technology, when implemented in a production level tool, help in achieving improved performance for real scientific and engineering applications on state-of-the-art parallel systems? In this paper, we evaluate the effectiveness of the SGI compiler in parallelizing Overflow, a 40,000 line production CFD code, on a 32 processor Origin 2000. Based upon our experimental results and user experiences, we describe some desirable properties of the compilation technology and software tools that would be helpful to the applications community.
