Execution efficiency of Fujitsu FX1 based supercomputer ranked 2nd in the world: Fujitsu Limited has announced that a Fujitsu supercomputer system is included in the latest edition of the TOP500 List supercomputer performance ranking, presented at the SC08 conference sponsored by the University of Texas at Austin. The system, built around Fujitsu FX1 advanced technical computing server, achieves an outstanding execution efficiency of over 89%. The latest TOP500 List includes Fujitsu’s new supercomputing system, as shown below. At more than 89%, this system’s execution is remarkably close to its theoretical performance limit, making it one of the most efficient supercomputer systems in the TOP500. Rank: 222 JAXA (Japan Aerospace Exploration Agency) JAXA Supercomputer System (FX1 advanced technical computing server) SPARC 64 VII 18.54 teraflops Execution efficiency: 89.81% This result is the product of a combination of the high-performance hardware technology in the FX1 technical computing server, Parallelnavi software that extracts the maximum performance from that hardware, and system-configuration technology. The supercomputer is part of the system Fujitsu is developing for the Japan Aerospace Exploration Agency, or JAXA, an independent administrative agency. It will comprise 3,392 nodes and achieve theoretical peak performance of 135 teraflops when the system begins full operations in April 2009. This supercomputer system will be used for advanced numerical simulations in developing rockets and aircraft as the core computation engine.
