The U.S. Department of Energy (DOE) chose IBM to build a new supercomputer for its Los Alamos National Laboratory in New Mexico, IBM announced Wednesday.Named "Roadrunner," the new machine comes with a price tag of US$35 million, the amount allotted by the U.S. Congress to the DOE\u2019s National Nuclear Safety Administration for its purchase.One potential use for Roadrunner is to monitor and maintain the U.S. nuclear weapons stockpile. DOE officials said they would monitor the computer\u2019s development to see if it meets the criteria to perform that task. The DOE has used supercomputers to keep an eye on the health and readiness of the United States\u2019 nuclear weapons, in lieu of actual underground nuclear tests.Roadrunner will run Red Hat\u2019s version 4.3 Linux operating system, and will be built entirely with commercially available hardware running two different types of processors, IBM said. The company will use IBM x3755 systems, with Advanced Micro Devices\u2019 Opteron processor, alongside IBM BladeCenter H systems with Cell processors.-Steven Schwankert, IDG News Service (Beijing Bureau)Related Link:\n\nU.S. Supercomputer Gets Performance BoostThis article is posted on our Microsoft Informer page.\u00a0For more news on the Redmond, Wash.-based powerhouse, keep checking in.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
