CERN Researchers Explore x86 Alternatives

Oct 28, 2014 |

Energy consumption has become a constraining feature on the growth of computing systems, such that the industry has shifted its focus from pure performance to performance-per-watt. As a result, there is increased interest in newer chip architectures that emphasize energy efficiency. An international group of researchers with ties to CERN are especially concerned with the effect these power constraints Read more…

Quick Change Material Begs Post-Silicon Consideration

Sep 22, 2014 |

With Moore’s law in peril, the search is on for the next computing substrate. Keeping up the pace of progress in an ever more compute and data driven world will likely require a post-silicon invention that can satisfy humanity’s need for faster, smaller, greener and more powerful computers. In recognition of the size and speed Read more…

GPUs Advance Deep Learning

Sep 18, 2014 |

Over the last decade, GPU-acceleration techniques have infiltrated the high-end of supercomputing, but increased adoption of GPUs is occurring in other compute-driven disciplines too, like deep learning, one of the fastest growing segments of the machine learning field. The trend toward accelerated computing reached a new high at last week’s ImageNet Large Scale Visual Recognition Challenge. The event, Read more…
