No changes in the TOP3 of TOP500 supercomputersMannheim 08 jun 2000 The first three positions of the TOP500 of the most powerful supercomputers remain unchanged: First is the Intel ASCI Red machine at Sandia, second is the IBM ASCI Blue Pacific at Lawrence Livermore and third is the SGI Asci Blue Mountain at Los Alamos, all in the USA. The first non USA machine is the Hitachi at the Leibniz Rechenzentrum in Munich. Surprisingly, Hitachi has 3 machines in the TOP10, the same number as Cray Inc, IBM has two machines and SGI and Intel each one.
In the June 2000 list, not much is left of what was once a Cray dominated list. With the selling of the old Cray division to Tera - and the change of name of that company to Cray Inc. , the "real" Cray machines count for only 54 of the machines. IBM is clearly in the number one position with 144 machines (up 3 from half a year ago). Sun is second with 121 machines. The third place is for SGI with 62 machines. Compaq posts the largest growth percent wise: going from two to six machines. The Japanese vendors Hitachi and NEC did relatively well and now have more entries than half a year ago. Fujitsu on the other hand, lost 7 machines and is now on 19. Europe is not longer present in the TOP500 als manufacturer: both machines in Bonn and Paderborn dropped out of the list and no new one came in. Self-made machines, clusters, did not really break-through. Only 4 of them can be found in the list, compared to 3 half a year ago. Looks like it is not so easy to build a supercomputer of your own after all. In performance, aggregated Rmax figures, the list for the vendors looks a bit different. IBM leads with 18.5 Tflop/s, but Cray Inc. is not far behind with 14 Tflop/s . With 6.3 Tflop/s, SGI beats SUN (6.2 Tflop/s). Hitachi is with 5.4 Tflop/s the first Japanese vendor.
