A comparison of 12 parallel FORTRAN dialects

Abstract

A simple program that approximates pi by numerical quadrature is rewritten to run on nine commercially available processors to illustrate the compilations that arise in parallel programming in FORTRAN. The machines used are the Alliant FX/8, BBN Butterfly, Cray X-MP/48, ELXSI 6400, Encore Multimax, Flex/32, IBM 3090/VF, Intel iPSC, and Sequent Balance. Some general impediments to using parallel processors to do production work are identified.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
