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.”

Why Create a New Programming Language with Chapel?

Brad Chamberlain

“Scalable parallel programmers (and desktop parallel programmers, for that matter) would benefit greatly from a productive new language supporting better syntax, features and optimizations than today’s parallel notations offer. HPC has a rich set of lower-level technologies upon which to build and numerous failed parallel languages from which to learn.”

A new MPI book is available for pre-order on Amazon. Written by William Gropp, Torsten Hoefler, Ewing Lusk, and Rajeev Thakur, Using Advanced MPI: Modern Features of the Message-Passing Interface offers a practical guide to the advanced features of the MPI (Message-Passing Interface) standard library for writing programs for parallel computers. It covers new features added in MPI-3, the latest version of the MPI standard, and updates from MPI-2.

SDSC to Simplify Data Sharing with SeedMe Project

This image and related research data, one of numerous projects being shared and stored using SeedMe, shows a simple model of geodynamo used for benchmark codes. The view is from center toward one of the poles, and the cones show convective flow toward higher temperature (light green to dark green with increasing velocity) in a spiraling form caused by rotation. The shells of various colors depict temperature, increasing from the outer boundary towards the interior.Courtesy of Amit Chourasia*, Ashley Willis^, Maggie Avery*, Chris Davies*#, Catherine Constable*, David Gubbins#. *UC San Diego, ^University of Sheffield, #University of Leeds, UK.

Researchers at the San Diego Supercomputer Center (SDSC) at the University of California, San Diego have received a three-year, $1.3 million award from the National Science Foundation (NSF) to develop a web-based resource that lets scientists seamlessly share and access preliminary results and transient data from research on a variety of platforms, including mobile devices.

Analyzing Time-series Data: The Kdb+ Community

Douglas Eadline

Douglas Eadline writes that while column-oriented databases and time-series analysis have been serving the financial sector for years, many may not know about the new resources available from the kdb+ community.
