Abstract

With the development of clusters based on high performance networks, it is now possible to design efficient Distributed Shared Memory systems. In this paper, we present the approach we choose to implement a high performance DSM system on top of a cluster by combining the use of low-latency communication protocols (MPI-BIP [12] on Myrinet networks) with multithreading approach (PM2 [11]). We will present our approach called Distributed Objects Shared MemOry System (DOSMOS system), its design and experiments performed on various communication libraries (PVM, MPI) and on various networks (Ethernet, Myrinet).
