Abstract

This paper describes a set of primitives (PARTI) developed to efficiently execute unstructured problems on distributed memory machines. These primitives have been incorporated into actual programs and kernels by hand. The development of the primitives were done such that the sequential code and the parallel code on each node would look identical. We have introduced a mechanism by which duplicate fetches of off-processor data between different loops are eliminated. This elimination of duplicate fetches appears to make a considerable impact on communications overheads.
