Effective use of shared memory multiprocessors

Conference ·
OSTI ID:5255016

We consider two application codes as case studies for the performance of shared memory multiprocessors. The first code is a packet switched network simulator, the second implements a new Monte Carlo algorithm for line transport. The codes are written in a portable parallel extension of the C programming language that can be compiled and executed on several shared memory multiprocessors, and that can be compiled into efficient serial code on any uniprocessor. We find that the latest crop of cost effective shared memory multiprocessors, when effectively used as multiprocessors on a single application, can exceed the performance of a well known supercomputer. 12 refs., 3 figs.
