Gray has held a variety of positions at ORNL since joining the staff in 1974. He most recently has been supervisor of the Computer-aided Manufacturing Section of the Computing and Telecommunications Organization and team leader of the integration thrust area of the DOE TEAM (Technologies Enabling Agile Manufacturing) project.
Before joining ORNL, Gray worked as a graduate research assistant at Vanderbilt University and at Los Alamos Scientific Laboratory, and was a consultant at the Oak Ridge Technical Information Center.
He is on the board of directors of the Coalition for Intelligent Manufacturing Systems and the technical advisory board of the National Industrial Information Infrastructure Protocol, a Department of Defense Technology Reinvestment Project. He represented ORNL at the 1992, 1993 and 1994 Commerce At Light Speed expositions.
Additionally, he represented ORNL on the CAM-I Next Generation Manufacturing Systems project and on several DOE complex-wide committees dealing in the areas of computer-aided design, manufacturing and engineering.
He is a member of the National Computer Graphics Association, the American Society of Mechanical Engineers, the Institute of Electrical and Electronics Engineers and the American Association for the Advancement of Science.
Gray has received two Enterprise Success Recognition Awards, two President's Awards and an individual Technical Achievement Award from Martin Marietta (now Lockheed Martin) Energy Systems.
Gray received a bachelor's degree in mechanical engineering and computer science, a master's degree in mechanical and environmental engineering and a doctorate in mechanical and structural engineering from Vanderbilt University. He is a member of Tau Beta Pi, the engineering honorary fraternity, and is a charter member of the Vanderbilt chapter of Pi Theta Sigma, the mechanical engineering honorary fraternity.
Gray lives in Oak Ridge with his wife, Nancy, and has two sons enrolled at Vanderbilt University, Harvey Jr., 21, and Michael, 18.
The CCII user facility serves as a focal point for ORNL/industrial interactions and partnerships in the critical area of high-performance computing. One of the CCII goals is to assist U.S. companies in achieving and maintaining global competitiveness by providing access to the technical expertise of ORNL scientists and engineers through high-performance computing collaborations. The center has numerous workstations for training along with conference areas and office space for support staff and industrial users.
Partners in the CCII gain access to the Intel XP/S 150, which is the most powerful computing engine in the Center for Computational Sciences (CCS) at ORNL. The system, currently ranked the third fastest computer in the world, has 1,024 computing nodes for a total of 3,096 processors, offering a peak performance of over 150 billion calculations per second (150 Gigaflops). The system was installed in January 1995 as the final in a series of computers resulting from a Cooperative Research and Development Agreement (CRADA) signed in 1992.
The CCS is one of two high-performance computing centers established by DOE to provide computing resources for "Grand Challenge" research. Grand Challenges involve solving problems ranging from energy research and environmental management to the human genome and the exploration of deep space. The solving of Grand Challenges is vital to the United States' industrial strength, educational system, environmental safety and national security.
You can learn more about this research and many other exciting projects by visiting ORNL on Oct. 21, 1995, during its Community Day event. Many of our facilities will be open to the public that day. For additional information, call ORNL Public Affairs, 865-574-4160.
ORNL, one of DOE's multiprogram national research and development facilities, is managed by Lockheed Marietta Energy Systems, which also manages the Oak Ridge K-25 Site and the Oak Ridge Y-12 Plant.
