Abstract

MPI has been the de facto standard for parallel computing for over a decade now, and remains mostly unchallenged as the only viable options for harnessing the processing power of massively parallel supercomputers. Alternative parallel programming paradigms have existed for quite some time, mainly in the form of PGAS languages [4,7], but have yet to deliver the necessary performance, robustness and portability needed to drive developers away from MPI.
