Intra node parallelization of MPI programs with OpenMP
, 1998
"... The availability of multiprocessors and high performance networks offer the opportunity to construct CLUMPs (Cluster of Multiprocessors) and use them as paxallel computing platforms. The main distinctive feature of the CLUMP axchitecture over the usual paxallel computers is its hybrid memory model ..."

movements inside the CLUMP 3) to limit the effort of the programmer while ensuring the portability of the codes on a wide vaxiety of CLUMP configurations. We investigate an approach based on the MPI and OpenMP standaxds. The approach consists in the intra-node paxallelization of the MPI programs
