Parallel Loops--A Test Suite for Parallelizing Compilers:Description and Example Results

ABSTRACT Several multiprocessor systems are now commercially available, and advances in com-piler technology provide automatic conversion of programs to run on such systems. However, no accepted measure of this parallel compiler ability exists. This paper presents a test suite ofsubroutines and loops, called Parallel Loops, designed to (1) measure the ability of parallelizing compilers to convert code to run in parallel and (2) determine how effectively parallel hardwareand software work together to achieve high performance across a range of problem sizes. In addition, we present the results of compiling this suite using two commercially available paral-lelizing Fortran compilers, Cray and Convex
