Abstract

The OpenMP programming model is based upon the assumption of uniform memory access. Virtually all current day large scale shared memory computers exhibit some degree of Non-Uniform Memory Access (NUMA). Should OpenMP be extended for NUMA architectures? This paper aims to quantify NUMA effects on the SGI Origin 3000 system as a prelude to answering this important question. We discuss the tools required to study NUMA effects and use them in the study of latency, bandwidth and the solution of a 2-D heat diffusion problem.
