Third is SUN with 113 systems and fourth HP with 45 systemsThen follow the
Japanese PVP vendors and the cluster systems. There are tow machines in the list
built in Europe: The Siemens HpcLine on position 351 at the University of Paderborn and the Parnass2 cluster at the University of Bonn at position 454.
Although in number, IBM is leading, in installed performance, SGI/Cray is
leading with 19.5 Tflop/s of installed power. IBM has 13.7 and SUN 4.8 followed
by Fujitsu with 2.9 Tflop/s.
Commercial use of supercomputers is growing strongly: Almost half of the
machines (246) are used in industry, although the bigger machines are still to
be found in research centres.
The decline of vector machines (PVP's) seems to have stopped, although MPP is
the dominant architecture in the TOP500. There are 62 PVP machines in the
TOP500: the Fujitsu, Hitachi and NEC machines and 10 Cray T90 systems.
More information on the list can be found at the TOP500 web site.
