Intel brochure - 11/91

All changes are from June 2001 to November 2001:

ASCI White is again #1 with unchanged performance of 7.2 TF/s on the Linpack
Three systems are new in the TOP10:
- at #2 with 4 TF/s a Compaq AlphaServer installead at Pittsburgh Supercomputing Center
- at #6 with 2 TF/s a second Compaq AlphaServer at the Los Alamos National Lab
- at #10 with 1.3 TF/s a IBM SP Power3 system installed in Germany at the National Weather forecast center (Deutscher Wetterdienst) in Offenbach
Lawrence Livermore National Lab has installed an additional 1.1 TF/s IBM Power3 system, which is listes at #15
This brings the number of systems exceeding the 1 TFflop/s mark on the Linpack up to 16
30 systems have peak performance above 1 TFlop/s including two self-made clusters:
- CPlant at Sanida at #30 and
- Titan at NCSA at #31
1.29 Tflop/s is the entry point for the Top 10
5 of the TOP10 systems are from IBM, 2 from Compaq, and one from Intel, Hitachi, and SGI.
8 of the TOP10 systems are installed in the US, and one in Japan and Germany each.

The new entry level of 94.3 GF/s would have been enough to be listed on position 295 in the last TOP500 just 6 month ago
Total accumulated performance is 134.4 TFlop/s compared to 108.8 TFlop/s 6 month ago
Entry level is now 94.3 GF/s compared to 67.8 GF/s 6 month ago In June 1993 no system exceeded this limit. From the Nov 1993 list only the "Numerical Wind Tunnel" at NAL in Japan exceeded this limit. This system is actually still on the list with improved hardware and performance at position 130.
The entry point for the top100 moved from 241 GF/s to 300 GF/s.
The first Itanium cluster is at the NCSA at #39 with 678 GF/s.
The first Windows2000 cluster is at the Cornell Theory Center at #320 with 121 GF/s.

The US keeps it's prime position as supercomputer user and producer with only little changes in geographical distribution
The number of machines used in industry increased again to 261 from 236.
The number of machines used in research stayed stable at 112 (from 118).
The number of machines used in academic declined slightly to 83 from 92.
IBM is again leading the TOP500. It is still leading the list with respect to the number of systems installed (32% down from 40%) and the installed performance with a stable share of 37%.
Hewlett-Packard made a big jump forward and has 153 systems (30%) in this list compared to only 41 in June 2001. All these systems are smaller in size. The first one appears at position 148. As a consequence the total HP share of installed Linpack performance is comparably smaller with 15% but still sufficient for position 2 in this category.
SGI, Cray and Sun follow in the number of systems with 41 (8%), 39 (8%), and 31 (6%) respectively.
With respect to installed performance Cray Inc. keeps the third position with 11% ahead of SGI (8%) and Compaq (8%).
