ASCI Red still unchallenged in TOP500

Mannheim, 18 June 98 In the new list of most powerful supercomputers in the world, ASCI red at Sandia Laboratories is still on number one. Hans Meuer, who presented the new June 1998 list at the Mannheim Supercomputer Seminar, estimates the machine is so powerful that it will stay on the TOP500 list until after 2005. The machine has a benchmark performance of 1.3 Tflop/s. Second in the list is a new SGI/Cray T3E at an American Governement site with almost 0.9 tflop/s. First Europeam machine is at rank 4: a Cray T3E at UK met in Bracknell, England. In the TOP20 there are 6 European centres, housing all Cray T3E systems. At place 19 is the first Japanese machine in Europe: the Fujitsu at the european Centre for Medium Range Weather forcast.

The follwing table shows the top 10 machines in Europe. The rank is the place in the TOP500. The Rmax the performance in Mflop/s of the machine on the Linpack yardstick.
