Extending OpenMP for Agent Based DSM on GRID

This paper discusses some of the salient issues involved in implementing the illusion of a shared-memory programming model across a group of distributed memory processors from a cluster through to an entire GRID. This illusion can be provided by a distributed shared memory (DSM) system implemented by using autonomous agents. Mechanisms that have the potential to increase the performance by omitting consistency latency intra site messages and data transfers are highlighted. In this paper we describe the overall design/architecture of a prototype system, AOMPG which integrates DSM and Agent paradigms and may be the target of an OpenMP compiler. Our goal is to apply this to GRID Applications. Keywords— Distributed shared memory; AOMPG; Agent; GRID.
