In chip multiprocessors (CMPs), maintaining cache coherence can account for a major
performance overhead. Write-invalidate protocols adapted by most CMPs generate high …

In many numerical simulation codes the backbone of the application covers the solution of
linear systems of equations. Often, being created via a discretization of differential …

Partitioned Global Address Space (PGAS) languages offer significant programmability
advantages with its global memory view abstraction, one-sided communication constructs …

Many and multicore architectures put a big pressure in parallel programming but gives a
unique opportunity to propose new programming models that automatically exploit the …

This paper presents the measurements of the MPI point-to-point communication
performances on Razi and Haitham clusters by using SKaMPI, IMB and MPBench …

The performance of MPI implementation operations still presents critical issues for high
