The semi-annual TOP500 list released in November 1997 ranked the National Energy Research Scientific Computing Center's Cray T3E-900 supercomputer as the most powerful unclassified machine in the U.S. and the fifth most powerful in the world.

NERSC provides leading-edge computational science support to hundreds of researchers across the nation with its Cray T3E-600 (ranked 84th), its Cray C90 (number 313); and cluster of four Cray J90se machines.

The TOP500 list, compiled by scientists at the University of Tennessee and Mannheim University in Germany, can be found at www.netlib.org/benchmark/top500.html.
