Top500 Supercomputers List Includes Four Alliance Systems

released June 13, 2000

The latest edition of the Top500 list of the world's most powerful supercomputers includes Alliance supercomputing systems from NCSA, the Maui High Performance Computing Center (MHPCC), the University of Kentucky, and Boston University.

For the first time, the Alliance's NT supercluster at NCSA made the Top500 at position 207. One of only 11 clusters on the list that were built with commodity parts, the supercluster is the higher ranked of the two clusters running Microsoft's Windows NT operating system. The cluster achieved performance of 62.6 billion floating-point operations per second (gigaflops), according to the list. The highest ranked Alliance system is the 1,024-processor Origin2000 system at NCSA, in 52nd place with achieved performance of 265 Gflops. Two 128-processor configurations of NCSA's Origin2000 rank 302 and 303 on the list. Other Alliance computing systems on the list are the IBM SP Power3 and IBM SP2 at MHPCC, which rank 97 and 124 respectively, the Hewlett Packard N4000 system at the University of Kentucky, which ranks 201, and the Boston University Origin2000 array, which ranks 251.

The Top500 list is compiled twice a year by Jack Dongarra, a researcher at the University of Tennessee, Knoxville, and an Alliance partner, and by Hans Meuer and Erich Strohmaier of the University of Mannheim in Mannheim, Germany. Performance rankings are based on the best Linpack benchmark performance achieved. For more on the Top500 list, see http://www.Top500.org/.
