June 2000
The 15th TOP500 list was published at the Supercomuter 2000 in Mannheim (June 8 - 10, 2000 ).
For the second list in succession, IBM is number one with respect to the number of installed systems with 144 systems ahead of Sun with 121. SGI now without Cray systems has 62 systems and Cray Inc. has 54 systems on the new TOP500 closely followed by HP with 47 systems. With respect to the installed performance IBM was also able to claim the lead with 18.5 TFlop/s ahead of Cray Inc. with 14.0 TFlop/s. SGI and and Sun follow with 6.3 and 6.2 TFlop/s.
The US ASCI system still holds the first three spots unchanged from the last list in November 1999. The Intel ASCI Red system at Sandia National Laboratory with achieved performance of 2.38 TFlop/s using 9632 Pentium processors remains the number one computer. The ASCI Blue-Pacific system at Lawrence Livermore National Laboratory is second with 2.14 TFlop/s and the ASCI Blue Mountain system at Los Alamos National Laboratory is number three with 1.6 TFlop/s. In addition to these three systems there are two new systems exceeding the 1 TFlop/s level on the Linpack benchmark. A new IBM SP system at IBM which will be installed at NAVOCEANO and an Hitachi SR8000-F1 installed at the Leibniz Computing Center in Munich. This is the first Japanese system exceeding 1 TFlop/s, the first such system outside the USA and the first Teraflops system at an academic site. However the TOP500 already contains 12 systems exceeding 1 TFlop/s peak performance.
There are 18 systems with more than 1000 processors in the TOP500 and out of these 7 have 2000 processors or more. The three largest systems are the 3 ASCI systems which lead the TOP500.
The list continues to show exponential growth in all ranges of performance. 24 systems exceed the mark of 500 GFlop/s this time. The last entry of the TOP500 list shows now a performance rate of 43.82 GFlop/s compared to 33.09 GFlop/s in November 1999. The average growth rates per year of this entry level performance is a factor of 2. This observed performance growth is above the growth predicted by Moore's Law which states a factor of 2 in 18 month (1.6 per year). The total accumulated performance of all 500 systems grew from 50.97 TFlop/s in November 1999 to 64.3 TFlop/s in June 2000.
