Rank Manufacturer (GFlops) Processors 1. IBM ASCI White,SP Power3 375 MHz [7226.00] [8192] 2. IBM SP Power3 375 MHz 16 way [2526.00] [2528] 3. Intel ASCI Red [2379.00] [9632] 4. IBM ASCI Blue-Pacific [2144.00] [5808] 11. Cray Inc. T3E1200 [1127.00] [1900] 439. Presto III Athlon 1.333 GHz [77.40] [78] Interesting is of course the AMD which gets almost 1 GFlop per processor where the Cray by far does not get 1 GFlop per processor. Bottom line: isn't your beloved Cray out-performed by nowadays micro processors available from your local super market? Ed
