The “Tiny Titan” parallel computer has become interactive display at the American Museum of Science and Energy at Oak Ridge. Constructed last year at ORNL, Tiny Titan is a nine-node scale-model of Titan designed to make it easier for students to understand how a supercomputer works.

Contrasting how Japan and Europe Promote the Use of HPC

pracedays1

Europe and Japan have come to the same conclusion; HPC resources must be shared and not monopolized by the individual owners of the computer systems themselves. And both have set up bodies to coordinate that process of sharing which bear remarkable resemblances to each other.

Supercomputing the Interior Dynamics of Stars and Giant Exoplanets

Night-side view of magnetic field lines in a simulation of a "hot Jupiter" exoplanet. Simulations like these help researchers better understand the interior dynamics of these planets and learn more about how they may have formed. Magenta indicates magnetic fields with positive polarity, and blue indicates fields with negative polarity. Tamara Rogers, Jess Vriesema, University of Arizona

Over at the NASA Ames Research Center, Michelle Moyer writes that the agency is using supercomputer simulations to explore the interior dynamics of stars and giant exoplanets.

Video: Mont-Blanc Prototype One Step Closer to Exascale

“Early in February, Barcelona Supercomputing Center (BSC) successfully deployed the Mont-Blanc prototype. After three years of intensive research effort, the team installed a two-rack prototype which is now available to the Mont-Blanc consortium partners. This has been a formidable challenge as this is the first time that a large HPC system based on mobile embedded technology has been deployed and made fully operational to a scientific community composed of scientists of six of the most important research centers in Europe.”

ISC 2015 Interview: Programming Models on the Road to Exascale

Dr. Michèle Weiland, EPCC

ISC 2015 will host a number of sessions on Exascale computing next month in Frankfurt. In what looks to be one of the highlights of the conference, Bill Gropp, Georg Hager, and Paul Kelly will discuss Programming Models on the Road to Exascale. To learn more, we caught up with the Session Chair, Dr Michèle Weiland, who serves as a Project Manager at the EPCC supercomputing center at the University of Edinburgh.

GPU Accelerated Quantum Chemistry: A New Method

sara

“The ability to accurately and efficiently study the absorption spectra of large chemical systems necessitates the development of new algorithms and the use of different architectures. We have developed a highly parallelizable algorithm in order to study excited state properties with ab initio electronic structure theory. This approach has recently been implemented to take advantage of graphical processing units to further improve efficiency.”

Podcast: Geoffrey Hinton on the Rise of Deep Learning

CHY4y4HUcAEq0MR

“In Deep Learning what we do is try to minimize the amount of hand engineering and get the neural nets to learn, more or less, everything. Instead of programing computers to do particular tasks, you program the computer to know how to learn. And then you can give it any old task, and the more data and the more computation you provide, the better it will get.”
