Agenda

ERSUG Meeting

July 11-12, 1994

Holiday Inn, Crowne Plaza

Rockville, MD

The Energy Research Supercomputer Users' Group (ERSUG) will meet at the Holiday Inn, Crowne Plaza in Rockville, MD on July 11-12, 1994. In the past, this meeting has combined presentations describing work-in-progress at NERSC with lively user discussions in the areas of the services and capabilities provided by NERSC. For this particular meeting, however, the focus will change somewhat. First, more emphasis will be put on future services, and second, the ERSUG meeting will be combined with the Energy Research Power Users Symposium (ERPUS). The session dedicated to ERPUS will occur on the second day of the two day ERSUG meeting and will be devoted to user presentations describing results obtained through the Special Parallel Processing (SPP) program at NERSC, as well as results obtained through use of other DOE high-performance systems.

The general theme of the first day of the ERSUG meeting will be the realized and projected improvements in the NERSC computing environment as well as on some remaining bottlenecks inhibiting most efficient access to system resources. A report from the committee to study options for controlling disk space usage will be part of a discussion of integrating host disk systems with AFS and archival storage at NERSC. There will be a progress report from ESNet and a detailed report on the transition to X-windows as a baseline standard for our users as we move into an era in which vendor software is driven by, and only compatible with, X-based standards.

Also on the first day, a new program initiated by the Office of Scientific Computing to arrange for Massively Parallel (MP) computing access will be described. NERSC Principal Investigators are now applying for access to parallel computers at the High Performance Research Supercomputer Centers at Los Alamos and Oak Ridge and to the Livermore T3D. Such access will allow scientists to develop applications in anticipation of the arrival of the NERSC MP system. Following this will be an update on the status of the NERSC procurement and a discussion of the anticipated impact that the transition will have on our users. This will include an approach for addressing the capacity-capability antithesis, not only during the transition period, but also beyond.

Since the meeting is dominated by what is about to happen rather than by what has happened, the NERSC staff will prepare a number of short documents describing recent progress and the status of critical areas. These will have to substitute for detailed presentations and will include topics such as the Energy Research Decision Package (ERDP), Centralized User Bank (CUB), etc.

We expect this meeting to be very stimulating; its focus on the present will be on extracting the maximum out of existing resources, and the focus on the future will be on planning a feasible and realistic path to effective use of new technologies. In this journey, the major constraints will be to find a reasonable path for all of our users regardless of their computing requirements, since good science is not always the biggest science...
