Viewing supercomputers as crucial to scientific discovery, the Energy Department announced plans Wednesday to build the world’s fastest computer at a research laboratory in Tennessee.


The supercomputer to be built at the Oak Ridge National Laboratory will be funded over the initial two years by federal grants totaling $50 million.



The project submitted by Oak Ridge scientists envisions a computer capable of sustaining 50 trillion calculations per second.



The Energy Department project will involve Cray Corp., International Business Machines and Silicon Graphics Inc., all private companies that have been deeply involved in high-performance computing research.
