Distributed Virtual Supercomputers
Sponsor: Sandia National Laboratories

Technical Chair: Neil Pundit, 505-845-7601
Administrative Contact: Carmela Andrade, 505-844-2345
This year’s program included:
- succinct visions from leaders;
- Technology Sessions exploring burning issues;
- Panels exposing the controversies with brief statements (of <5 minutes each) and vigorous audience participation;
- an Integration & Testing Technology Session delving into such issues as installation, testing, operational readiness and support;
- an Applications Panel illustrating successes and drawing attention to the challenges ahead;
- a Usability Panel looking into such success metrics as reliability, availability, and modifiability;
- a CRYSTAL BALL session projecting the future of heterogeneous clusters, integrating SMPs, Petaflops computing, and web-supercomputing.
We concluded by summarizing the highlights of the two-day activities, and getting a program committee to engage us in planning for the 5th Workshop in 2001. This was an immense immersion experience.

| 2:00 pm | Planning for 2001 Audience participation is sought in planning for the workshop in 2001. The host for 2001 is ORNL, represented by Al Geist. It will be held in the USA around March 2001. Al listened to some suggestions for possible sites, and will seek a consensus. While many praised the New Orleans workshop, it was suggested that greater audience participation should be a goal in the future. The following volunteered to serve on the Program Committee for 2001: Al Geist Neil Pundit Pete Beckman Terri Quinn Ralf Gruber Bill Saphir | |
