A Prototype Implementation of MPI for SMARTMAPmentation of MPI that uses SMARTMAP for intra-node message passing. SMARTMAP has several advantages over POSIX shared memory techniques for implementing MPI. We present performance results comparing MPI using SMARTMAP to the existing MPI transport layer on a quad-core Cray XT platform.

The Next Frontierpower of the new generation processors has thus greatly increased, but their programmability still lacks certainty. The many changes in the newest architectures have come so rapidly that we are still deficient in taking advantage of all the new features, in terms of high performance libraries and ap

Fault Tolerance for PetaScale Systems: Current Knowledge, Challenges and Opportunitiess successfully complete. Existing results for several key mechanisms associated with fault tolerance in HPC platforms will be presented during this talk. Most of these key mechanisms come from the distributed system theory. Over the last decade, they have received a lot of attention from the communi

MPI Must Evolve or Diet evolve to effectively use these types of architectures or it will die just like the vector programming models died. While applications may continue to use MPI, it is not business as usual in how communication libraries are being changed to effectively exploit the new petascale systems. This talk p

MPI and Hybrid Programming Models for Petascale Computing system. This system, funded by the National Science Foundation, will deliver a sustained performance of one to two petaflops for many applications in science and engineering..Blue Waters will support a variety of programming models, including the “MPI everywhere” model that is the most common among

Some Aspects of Message-Passing on Future Hybrid Systems (Extended Abstract)odes with each node having several multi-core CPUs. Parallel programming must combine the distributed memory parallelization on the node inter-connect with the shared memory parallelization inside each node. There are many mismatch problems between hybrid hardware topology and the hybrid or homogene
