SC 2003 Phoenix, Arizona November 15-21, 2003 Panel on "Supernetworking Transforming Supercomputing"
Moderator:
Panelists:
Description: A fundamental architectural shift has occurred in this decade, in that storage and particularly networking bandwidth are growing much faster than Moore's Law. The super-exponential in bandwidth is caused by parallelization in the number of Lambdas, independent light paths down a single fiber optic, multiplied by the increase of the bandwidth of the individual light paths (DWDM). The TeraGrid was the first example of a national-scale supercomputer with dedicated optical paths -- 4x10Gbps. The Panel reviews the basic engineering trends in processors, storage and optics, and then examines a number of federally funded projects which are exploring the vision laid out by Steve Wallach at Supercomputing 2000 in which a petaflop computer by 2010 will be an optical switch with compute and storage peripherals. In addition, the Panel examines how dedicated multi-Lambda optical circuits could radically change the architecture of distributed cyberinfrastructure and the ability for application end-users to use that infrastructure to carry out 21st-century scientific research.

For the last decade, Moore's Law has dominated supercomputing architecture,
since it was on a steeper exponential than either bandwidth or storage.
Furthermore, during the 1990s, the commoditization of processors allowed for
super-exponential growth in computing power through the parallelization of
processors -- that is, we were able to multiply Moore's Law for the growth of
individual processor speeds by the 500-fold increase in the number of processors
in a single parallel computer (from 4 processors in the early 1990's to 2000
processors today).
Jason Leigh and Luc Renambot conducting OptIPuter optical multicast
demonstrations on the GeoWall2 tiled display at SC 2003 using the Glimmerglass
Networks System 300E Layer 1 Fiber Switch. Leigh and Renambot are OptIPuter
partners from the University of Illinois at Chicago's Electronic Visualization
Laboratory (UIC/EVL). The GeoWall2's first public showing was in the SC 2003
Research Exhibition.
OptIPuter principal investigator Larry Smarr, with UCSD/NCMIR and UIC/EVL
partners Mark Ellisman and Jason Leigh, describe the benefits of the
high-resolution GeoWall2 tiled display to a SC 2003 attendee.
