ARMONK, N.Y. - 15 Nov 2002: An independent study released today found that IBM is the world's leading provider of supercomputers with a total of 93 Teraflops of power (trillions of calculations per second) on the TOP500 List of Supercomputers. This represents more than 31 percent of the total processing power on the list and is greater than 43 percent ahead of the runner up, Hewlett Packard, with 64.8 Teraflops.

In the exclusive realm of the top 100 most powerful supercomputers in the world, IBM accounted for 43 systems, more than three times the number of HP's 13 systems on the List.

"IBM has committed our deep technology and research capabilities to become the leader in supercomputing," said Peter Ungaro, vice president of High Performance Computing, IBM. "In recent years new applications using scalable clusters and Grid systems have exploded. We expect that the tremendous innovation in areas like life sciences, digital media, and computationally intensive simulations will continue to fuel the use of powerful high-end systems. IBM intends to continue our track record of innovation around Grid computing and on demand delivery of supercomputing in the years ahead."

Based on the success of IBM's POWER™ microprocessor technology, IBM supercomputers are the most widely used in the world for the largest applications of scale. IBM supercomputers are used for applications such as those exploring medical mysteries in life sciences, making cars safer in automobile design, and optimizing investment strategies in financial markets.

The "TOP500 List Supercomputing Sites" is compiled and published by supercomputing experts Jack Dongarra from the University of Tennessee and Erich Strohmaier and Hans Meuer of the University of Mannheim (Germany). The entire list can be viewed at

IBM also announced today the eServer™ p655, an ultra dense UNIX® server targeted at the high performance computing market that packs up to 128 POWER4™ processors in a single rack. (See separate announcement.)
