Pete Beckman Presents: Exascale Architecture Trends

“Over the past thirty thirty years there have been several predictions of the eminant cessation of the rate of improvement in computer performance. Every such prediction was wrong. They were wrong because they hinged on unstated assumptions that were overturned by subsequent events.”

“SURF allows you to set up a light path: a direct, secure, and fast connection between 2 points, for example between a researcher in the Netherlands and a telescope in China. This offers unique, worldwide possibilities, for example for more efficient research, for sharing facilities or large datasets, or for creating backups.”

In this video, Dr. Norm Uren and Dr. Matt Lamont describe how seismic processing with HPC is used to find new oil and gas resources. As reported here on insideHPC, DownUnder GeoSolutions (DUG) is making great leaps in performance using the Intel Xeon Phi.

Slidecast: Energy-efficient Computation

mark

“A crazy idea was born at ISC14 while answering questions about the new energy metrics in Allinea Performance Reports and Allinea MAP – could the information in these reports show us an easy way to increase energy efficiency without having to change the program? The idea was to use CPU frequency scaling to run memory-bound jobs at a lower clock frequency. In Lazy Energy Efficiency Challenge One, I found that on a synthetic benchmark I could increase the iterations per watt by 19% on a memory-bound code.”
