Distributed Shared Memory - OMSCS Notes

Webfor shared memory architectures [4]. In this paper, we present an approach for automatically obtaining efﬁcient target code for distributed memory architectures, i.e., we include the generation of the necessary communication code. The paper is organized as follows. First, we give a very brief description of the polytope model. Then, we illustrate Webfor software distributed shared memory systems. Two distinct approaches have been used: the ﬁne-grainap-proach that instruments application loads and stores to support a small coherence granularity, and thecoarse-grain approach based on virtual memory hardware that provides coherence at a page granularity.
