Two-thirds of the Top500 machines are powered by Intel's chips, with 81 of the 333 systems using the chip giant's EM64T-based processors. IBM's Power chips appeared in 73 systems. Intel's rival Advanced Micro Devices (AMD) had processors in 55 systems, more than doubling its standing on the last list put out in June.
Geographically speaking, the U.S. dominates the list, accounting for 305 of the Top500 supercomputers, trailed by Europe with 100 systems and Asia with 66 machines. Germany, which had been the leading European supercomputer country with 40 systems on June's Top500 list, only had 24 systems on the new list. with the U.K. becoming the number-one European player with 41 systems up from June's 32 systems.
The Top500 list was compiled by Erich Strohmaier and Horst Simon of the National Energy Research Scientific Computing Center (NERSC)/Lawrence Berkeley National Laboratory, Hans Meuer of the University of Mannheim, Germany, and Jack Dongarra of the University of Tennessee, Knoxville.
