"Linux will be the main operating system for IBM's upcoming family of 'Blue Gene' supercomputers-a major endorsement for the operating system and the open-source computing model it represents.
"IBM's $100 million Blue Gene program is directed at creating, by late 2005 or early 2006, a new family of supercomputers that will be able to perform a quadrillion calculations per second (one petaflop). "Blue Gene/L, the first member of the family, will contain 65,000 processors and 16 trillion bytes of memory. Due in 2004 or 2005, the system will be able to perform 200 trillion calculations per second. Lawrence Livermore National Laboratory will use the system for performing nuclear weapons simulations." http://news.com.com/2100-1001-963285.html Mark Post
