The Design of MPI Based Distributed Shared Memory Systems to Support OpenMP on Clusters

Wong, H'sien; Rendell, Alistair


OpenMP can be supported in cluster environments by using distributed shared memory (DSM) systems. A portable approach for building DSM systems is to layer it on MPI. With these goals in mind, this paper makes two contributions. The first is a discussion about two software DSM systems that we have implemented using MPI. One uses background polling threads while the other uses processes that are driven only by incoming MPI messages. Comparisons of the two approaches show the latter to be a more...[Show more]
