Working with PRACE: an insider’s perspective

Professor Stephan Roche of the Catalan Institute of Nanoscience and Nanotechnology in Spain is one of the early adopters of high-performance computing in Europe’s Graphene Flagship initiative. His latest project has received 22 million core hours from PRACE, the Partnership for Advanced Computing in Europe. 

Roche has fifteen years of experience in developing novel algorithms and computational approaches that can be used to investigate quantum transporting in complex materials such as graphene. Here, we speak to him about his experience of working with PRACE.

Supporting world-class research at ISC’14

Last week, iSGTW attended the International Supercomputing Conference (ISC’14) in Leipzig, Germany. The event featured a range of speakers representing a wide variety of research domains. Awards given by PRACE and Germany’s Gauss Centre for Supercomputing highlighted some of the outstanding research on show at the event. And, of course, the new TOP500 list of the world’s fastest supercomputers was announced.
