Science Case for Large-scale Simulation


The DOE Office of Science workshop on the Science Case for Large-scale Simulation was held in Arlington, VA, on Tuesday, June 24, 2003, through Wednesday, June 25, 2003. The workshop is a major activity in an on-going process of demonstrating the need for new ultrascale computing facilities for Office of Science missions.

Workshop content will flow immediately into a report (to be published in July 2003) that is designed to assist in the FY 2005 budget process for the Office of Science. It will also identify specific areas in which additional (smaller and more focused) workshops may be scheduled throughout the year to follow, with the purpose of further demonstrating the opportunities of large-scale simulation for scientific breakthrough in certain areas.

The densely packed workshop schedule included three plenary presentations, three breakout sessions of approximately ten-way parallelism, summary reports from the breakouts, and response periods.

In the plenary sessions, Dr. Ray Orbach, Director of the Office of Science, charged the participants and previewed the Office of Science strategic plan, into which the results of this workshop will feed. Professor Peter D. Lax of the Courant Institute editor of the 1982 report, Large Scale Simulation in Science and Engineering, provided a personal historical perspective on the impact of that report- and advised the workshop concerning its own very similar calling in a very new computational era. John Grosh, Co-chair of the High End Computing Revitalization Task Force (HECRTF), addressed the participants on the context of this interagency task force, which had met the week preceding this workshop.
