Two new systems with Dolphin WulfKits in the TOP500Oslo 18 November 2002 The 20th Top 500 Supercomputers list, includes two new supercluster systems built with the Dolphin WulfKit high-speed interconnect. The systems, ranking 51 and 302, are installed at Linkoping University, Sweden, and Ruhr University, Bochum, Germany, respectively.
The Linkoping University supercluster is installed at the National
Supercomputing Centre. The 200 nodes in the cluster are interconnected as a
three-dimensional 5x5x8 torus, or logical cube. The superior performance, which
earned the cluster the 51st position on the Top 500 list, is achieved with 400
Intel(R) Xeon(TM) processors interconnected with the innovative Dolphin
WulfKit3, a high-speed interconnect that features a three-dimensional torus
distributed switching topology. Scali AS of Oslo, Norway, is the integrator for
the project.
The Ruhr University system is a 128-processor cluster featuring AMD(R)
Athlon(TM) MP 1600+ processors. With a Linpack performance of 235 GFlops, the
system ranks 302 on the Top 500 Supercomputer list. The system was recently
installed in the Theoretical Chemistry department at the University, where
researchers are seeking to bridge the gap between chemistry and physics through
understanding the structure, dynamics, and chemical reactions of complex
molecular many-body systems. Integration was handled by MegWare of Chemnitz,
Germany.
The Dolphin WulfKit system is a standards-based high-speed interconnect used to
cluster large numbers of servers creating a supercluster with performance levels
comparable to other supercomputers. These WulfKit-enabled superclusters are
typically used in highly demanding parallel processing applications in business
and research.
These two new systems join two other supercluster systems built with WulfKit on
the Top 500 list. Superclusters at Umea University (Sweden) and University of
California, Santa Cruz, ranked 124 and 215 respectively, first appeared on the
19th Top 500 list in June 2002.
