Voltaire Powers Roadrunner

DRESDEN, Germany -- Voltaire Ltd. (NASDAQ: VOLT) today announced that the companys InfiniBand-based switches are powering the world’s largest supercomputer for the National Nuclear Security Administration’s (NNSA) Los Alamos National Laboratory. The revolutionary new supercomputer, nicknamed Roadrunner, achieved sustained performance of 1,026 trillion calculations per second breaking the petaflop barrier and surpassing the performance of every other supercomputer operating today. Roadrunner has also claimed the number-one position on the new Top500 (www.top500.org) list released today. This represents a multimillion dollar deal for Voltaire for planned delivery in 2008.

Roadrunner is a collaborative effort between Voltaire, NNSA, IBM and Los Alamos National Laboratory that will primarily be used to ensure the safety and reliability of the nation’s nuclear weapons stockpile. It will also be used for research into astrophysics, energy, disease pathways and global climate.

“Architecting and deploying a new scale of supercomputer is a tremendous accomplishment. One of the pleasant surprises was the stability of the system as it scaled up in size,” said Andy White, Roadrunner Project Director at Los Alamos National Laboratory. “The incredible amount of compute power harnessed by this machine will further the country’s national security initiatives and aid in new scientific discoveries.”
