The International Exascale Software Project roadmap

Abstract: Over the last twenty years, the open source community has provided more and more software on which the world's High Performance Computing (HPC) systems depend for performance and productivity. The community has invested millions of dollars and years of effort to build key components. But although the investments in these separate software elements have been tremendously valuable, a great deal of productivity has also been lost because of the lack of planning, coordination, and key integration of technologies n… Show more

“…In this context, it is well known that data movement is becoming more energy hungry than processing data [1]. This implies that data synchronization and communication overheads, experienced by multi-threaded real-world applications, may have an enormous impact on such systems.…”

“…The increasing number of nodes in clusters decreases the mean time between failures (MTBF). While the MTBF was in the order of days [2], it will decrease to the order of minutes for exascale systems [3]- [5]. Therefore, HPC programmers must consider that their (long running) jobs will not finish without any hardware or software failure.…”
