We consider a certain class of parallel program segments in which the order of messages sent affects the completion time. We give characterization of these parallel program segmen...
The one-sided communication operations in MPI are intended to provide the convenience of directly accessing remote memory and the potential for higher performance than regular poin...
In SMP clusters it is not always convenient to switch from pure message-passing code to hybrid software designs that exploit shared memory. This paper tackles the problem of restru...
We introduce a refinement strategy to bring the parallel performance analysis closer to the user. The analysis starts with a simple high-level performance model. It is based on fir...

As the number of nodes in cluster systems continues to grow, leveraging scalable algorithms in all aspects of such systems becomes key to maintaining performance. While scalable al...
On recent PC graphics cards, fully programmable parallel geometry and pixel units are available providing powerful instruction sets to perform arithmetic and logical operations. In...
We propose lightweight middleware solutions that facilitate and simplify the execution of MPI programs across multidomain clusters. The system described in this paper leverages H2O...
