The paper presents Heterogeneous MPI (HeteroMPI), an extension of MPI for programming high-performance computations on heterogeneous networks of computers. It allows the applicati...
Researchers have recently proposed coupling small- to mediumscale multiprocessors to build large-scale shared memory machines, known as multigrain shared memory systems. Multigrai...
Software barriers have been designed and evaluated for barrier synchronization in large-scale shared-memory multiprocessors, under the assumption that all processorsreach the sync...
This paper describes performance tuning experiences with a three-dimensional unstructured grid Euler flow code from NASA, which we have reimplemented in the PETSc framework and p...

The MPI programming model hides network type and topology from developers, but also allows them to seamlessly distribute a computational job across multiple cores in both an intra ...
