Intra node parallelization of MPI programs with OpenMP

by Franck Cappello, Olivier Richard , 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 ..."
