Fujitsu's New Supercomputer System Ranked in Latest TOP500 List

- Execution efficiency of Fujitsu FX1 based supercomputer ranked 2nd in the world -

Fujitsu Limited

Tokyo and Austin, Texas, November 19, 2008

Fujitsu Limited announced today 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(1) 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 Customer System name
CPU Performance Execution
222 JAXA(Japan
JAXA Supercomputer
System(FX1 advanced
technical computing server)
SPARC 64 Ⅶ 18.54 teraflops(2) 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.

About the TOP500 list

The TOP500 List was created in 1993, and is updated twice a year (in June and November) to show the world's 500 fastest supercomputers as measured using the LINPACK parallel-processing benchmarking program.

About the FX1

The FX1, using a new architecture designed to extract the maximum performance from the SPARC64™ VII quad-core CPU developed by Fujitsu, together with a chipset that ensures a balanced memory bandwidth and a high-performance compiler realizes extremely efficient execution of calculations with the multi-core CPU system, something that has previously been very difficult.

In addition, through intelligent interconnects(3) that enable various types of calculation to be performed on data in the transmission pathway, a significant leap in the scalability of parallel applications is achieved. Moreover, the rich suite of development platform tools and operational functions delivered by Parallelnavi, the parallel-processing software that has a long track record in the field of technical computing, makes it easy to work in a high-performance parallel computing environment. The FX1's performance is 40 gigaflops(4) per node.

About Parallelnavi

It is a HPC middleware that includes an execution environment and a file system, in addition to having a development environment that includes a compiler needed for science and technology computation as well as a math library. Parallelnavi is available for all of Fujitsu's HPC platforms. Especially, the math library dictates LINPACK's processing performance to a large degree and it contributed extensively to the high efficiency measured in the latest test.
