DANCES with Big Data: Progress Update from XSEDE Meeting

Jul 22, 2016 |

Moving large datasets around HPC networks such as those of XSEDE is often challenging. While Internet2, the most commonly used backbone, is fast at 100GBS, local traffic to campuses often slows to 10GBS. At this week’s XSEDE meeting the DANCES (Developing Applications with Networking Capabilities via End-to-End SDN) project leaders reported first successful testing of Read more…

Report Addresses the Perils of Dark Silicon

Jul 21, 2016 |

Dark silicon refers to the processing potential that’s lost when thermal constraints disallow full CPU utilization. The gap between transistor scaling and voltage scaling combined with tighter integration of components (multicore, SoCs) has power density ramifications that are of particular concern for embedded computing, but high-performance computing faces similar “dark power” challenges. Bringing attention to this issue and exploring common solutions was the goal of the Dagstuhl Seminar 16052, “Dark Silicon: From Embedded to HPC Systems.”
