World's First Next Generation Cray XMT Successfully Installed at CSCS
July 18, 2011
CSCS is pleased to announce the successful installation of the world's first next generation Cray XMT supercomputing architecture manufactured by Cray Inc.
The single cabinet contains 16 quad-socket compute blades, 64 Cray Threadstorm CPUs with 32 GB per CPU and a total of 2 TB of memory. Following CSCS tradition the new supercomputer has been named after one of the most famous Swiss mountains, the Matterhorn, also visible on the front of the cabinet. The Cray XMT provides the programmer an illusion of a globally addressable flat memory hierarchy, thus avoiding the need for load balanced data partitioning and redistribution among processors.
Michele De Lorenzi interviewed Jim Maltby on the Cray XMT2 "Matterhorn" at the International Supercomputing Conference 2011 in Hamburg, Germany. Maltby is the top Cray expert on XMT architecture.
