Also, Chris Beggio posted SC stuff.

• Notes from chairman - SC now rivaling Siggraph in the giant tech conference arena
• Keynote from Bill Gates - “Computation has become a tool for all the sciences”, Windows 2003 computer server, Tight integration with dev studio and graphical workflow development, launch one of these graphical workflows on local machine, “personal windows 2003 server cluster” - (single box with 4-8 Intel machines), a larger Windows cluster, or a big Linux cluster
• Cluster Environment Tech papers

- 1,2, 3.

Today’s session is “Issues for the Future of Supercomputing” / “Impact of Moore’s Law and Architecture on Application Performance“, presented by:

• Erik DeBenedictis - Sandia
• David Keyes - Columbia University
• Peter Kogge - University of Notre Dame

Notes:

• SCaLeS
• NSF Reports covering cyber infrastructure
