Four Challenges Facing Exascale Application Prep

Jun 22, 2015 |

Worry over readying HPC applications for exascale computing isn’t new and various efforts are underway. Whether they are sufficient is a matter of debate. A major stumbling block, of course, is no one knows precisely what exascale architecture will look like. A recent paper (June 9) on arXiv.org from IBM Research and several European academic Read more…

Fixating on Exascale Performance Only Is a Bad Idea

Jun 15, 2015 |

Few in the computing industry dispute that achieving ‘exascale’ performance is worthy on its own merits. But fixating only on the magic milestone (10^18 FLOPS) misses an important point – HPC as currently practiced, even at the exascale level, won’t solve the grand challenges in science and society contends Dr. Sadasivan Shankar, Harvard University visiting Read more…
