This activity provides funding for equipment and personnel for the Scientific Applications effort at the National Energy Research Scientific Computing Center (NERSC). This effort provides high performance computing resources for investigators supported by the Energy Research often through collaboration with the NERSC staff. Mission areas of Energy Research include: Material Sciences; Chemistry; Geosciences; Biosciences; Engineering; Health and Environmental Research; High Energy and Nuclear Physics; Fusion Energy; and Mathematical, Information and Computational Science.
The Center serves more than 4,000 users working on about 700 projects, of which about 30% are university based, 65% are in National Laboratories, and 5% in industry. In FY 1996 NERSC operated 4 CRAY computers: a C-90 with 16 processors, with 256 Million words (Mw) of memory, a CRAY-2 with 8 processors with 128 Mw, a CRAY 2 with 4 processors and 128 Mw, and a J-90 with 32 processors and 512 Mw, and the National Education Supercomputer, a single processor CRAY XMP donated by Cray Research, which is available over the Internet to high schools for educational programs. The operating philosophy is not to continue to operate NERSC as a first class production computing facility as it successfully has for the last two decades, but to an interactive Center whose staff will collaborate with DOE/ER scientists and engineers to enable them to accomplish their missions through effective use of the Centers new computing systems with novel architectures. |

Implemented massively parallel computer in the production environment.
Delivered 576,000 Computer Resource Units (CRUs) to ER Programs. Supplied an additional 3 Terabytes of archival storage to ER programs. The Special Parallel Processing Program was expanded to 70,000 Computer Resource Units by 4Q95. SPP workshops were held for winning proposals. Brought the NSL technology-based archival storage system into limited production use. Brought up the Portable Batch System (PBS) to provide a uniform batch environment across all major platforms. |
While successfully delivering 600,000 Computer Resource Units (CRUs) in FY_1996 (more than in FY_1995 ) and an additional 3 Terabytes of archival storage to ER programs, the operating philosophy of NERSC was rewritten, the Center was recompeted, moved, and rebuilt at Lawrence Berkeley National Laboratory in response to a directive to operate the Center in a self sustaining mode for 20% less funding.
In FY_1996, the Center also acquired new computing systems that are not classical vector Supercomputers. These systems, J90s with a shared-memory multi-processor architecture and a T3E with a massively parallel architecture, will be acquired from SGI's Cray Research Division providing certain performance benchmarks are met. The new systems will increase the computational resources at the Center by more than 400% before the end of FY_1997. Also acquisitions of Mass Storage will improve this component of the Center's system by an order of magnitude in the same time span. |
Continue to rebuild the Center to effectively operate within the new philosophy primarily by hiring scientists and engineers trained in the mission disciplines of DOE Energy Research to work interactively with Energy Research users of the Center .
Install new computing and mass storage systems, bring into operation, and train and otherwise aid Energy Research investigators in effective use of the new Center. Expand the efforts of the Center to assess and use new computing, collaborating and communications technologies important to Energy Research. |
