Department of Energy

DOE faces unprecedented challenges challenges as it approaches the 21st century. DOE is committed to:reducing the global nuclear danger through its national security and nonproliferation activities; replacing underground nuclear testing with science; understanding and dealing with risks associated with environmental problems resulting from nuclear weapons production during the Cold War; promoting clean and efficient supply of energy; ensuring continuing US world leadership in science and technology research; and maintaining U.S. global competitiveness through leadership in environmentally-conscious materials, technologies, and industrial processes.

The DOE High Performance Computing Program is focused on providing DOE with tools to address these challenges. It is a forefront, diverse applied mathematical sciences, high performance computing, communications and information infrastructure program which spans the spectrum of activities from strategic fundamental research to technology development and demonstration. The diverse activities supported by this program are integrated to support two major strategic thrusts: National Collaboratories (NC) and Advanced Computational Testing and Simulation (ACTS).

The thrust in National Collaboratories is developing a set of tools and capabilities which will permit scientists and engineers working at different DOE and other facilities to collaborate on solving problems as easily as if they were in the same building.

The thrust in Advanced Computational Testing and Simulation is developing an integrated set of algorithms, software tools and infrastructure which will enable computer simulation to be used in place of experiments when real experiments are too dangerous, expensive, inaccessible, or politically infeasible. These two strategic thrusts support the underlying mathematical concepts and information technology needs of all Department of Energy (DOE) mission areas (e.g., Defense, Energy Efficiency, Environmental and Fossil programs, etc.) and the efforts in these areas are closely coordinated with related activities supported by Defense Programs.

The DOE program also supports and responds to the Energy Policy Act (EPACT) and to the High Performance Computing Act of 1991 (also known as the Gore Bill) and provides supercomputer access and advanced communication capabilities (through the ESnet computer network) to scientific researchers. Finally, the this program also serves as an advocate within the Department to formulate and coordinate the Department's National Information Infrastructure (NII) initiative, especially to promote economically beneficial energy-related 'National Challenges' applications such as energy demand and supply management and to develop the underlying technologies to enable these applications.
