Title:
Early Experiences in "T2K Open Super Computer (Todai Combined Cluster)" with AMD Quad-Core Opteron processors
Abstract:
The T2K Open Supercomputer Alliance (http://www.open-supercomputer.org/) was established primarily aiming at collaborative work on the specification design for new supercomputers procured by the following three member universities:
  • Center for Computational Sciences, University of Tsukuba
  • Information Technology Center, University of Tokyo
  • Academic Center for Computing and Media Studies, Kyoto University
This activity is for creative procurements at the initiative of universities based on technology market research, rather than those by choosing machines from product market and at the initiative of system venders. This creative and university-initiative approach results in open specifications, with respect to the architecture, software stack and usage of the new supercomputers, to give an efficient HPC solution with the most advanced technologies to a wide-spectrum of users in Japanese academe.

In the end of 2007, all of three universities decided to introduce AMD Quad-Core Opteron (Barcelona) based clusters, and three systems start operation for practical use in June 2008.

"T2K Open Super Computer (Todai Combined Cluster)" at the University of Tokyo by Hitachi Ltd. consists of 952 nodes, where each node has 4 sockets of Quad-Core Opteron (i.e. 4x4= 16 cores/node). Total peak performance is approximately 140 TFLOPS, total memory size is 32TB, and total storage is 1 PB.

In this presentation, brief overview the system and preliminary results of GeoFEM benchmarks will be presented.
