ARMONK, N.Y. - 23 Jun 2003: An independent study released today found that IBM is the world's leading provider of supercomputing power with a total of 130 Teraflops of power (trillions of calculations per second) on the TOP500 List of Supercomputers, representing more than 34 percent of the total processing power on the list. IBM's results are 44 percent better than runner up HP, finishing second with 90 teraflops of total processing power.

IBM's leadership in powering some of the world's biggest supercomputers is exemplified in the exclusive top 100 most powerful supercomputers in the world. IBM accounts for 50 percent of these systems versus 12 percent for HP. Additionally, IBM has 31 systems in the "Teraflop Club" versus HP's 7 systems. The Teraflop Club includes systems that perform greater than one trillion calculations per second.

"IBM has committed our deep technology and research capabilities to become the leader in supercomputing," said Dave Turek, vice president IBM Deep Computing. "Leveraging our strengths in technology and research with the sophisticated software and deep industry knowledge help customers solve real life business problems."

The "TOP500 List Supercomputing Sites" is compiled and published by supercomputing experts Hans Meuer of the University of Mannheim (Germany), Erich Strohmaier and Horst Simon from NERSC at the Lawrence Berkeley National Labs, and Jack Dongarra from the University of Tennessee.
