government and industry that advanced computer and telecommunications technologies could provide huge benefits throughout the research community and the entire U.S. economy. The Program is the result of several years of effort by senior government, industry, and academic scientists and managers to initiate and implement a program to extend U.S. leadership in high performance computing and networking technologies and to apply those technologies to areas of profound impact on and interest to the American people. The Program is planned, funded, and executed through the close cooperation of Federal agencies and laboratories, private industry, and academia. These efforts are directed toward ensuring that to the greatest extent possible the Program meets the needs of all communities involved and that the results of the Program are brought into the research and educational communities and into the commercial marketplace as rapidly as possible.
