The Gelato Sponsor known as “Energy Company” took two slots in the TOP100, ranking at 25 and 77, both with Itanium2-based machines from Hewlett-Packard running Linux. Gelato’s Founding Sponsor, the Hewlett-Packard Company, took 10 slots in the top 500: two are Itanium2-based machines, which came in at the 252 and 269 spots. With a total of 165 systems in the TOP500, Hewlett-Packard led the list for the fourth consecutive time as vendor of the largest number of HPC systems.

Itanium Scores Additional Spots in TOP500 According to Intel, Inc., (Nov. 16, 03) the Itanium2 architecture accounted for a total of 32 spots on the TOP500, an increase of 68 percent since last June’s list. They include an Itanium system of the Chinese Academy of Science, running a DeepComp6800, Itanium2 by Legend, which was ranked #14. The system is located at Zhejiang University, which is a Gelato Member. Coming in at #231 is the University of Gdansk in Poland, with “Holk,” an Itanium2 system by Optimus.

Growth of Cluster Systems Notable in this edition of the TOP500 list is the growth of cluster systems. Seven of the TOP10 supercomputers are clusters, while a total of 208 of the full TOP500 are now cluster systems, up from 149 six months ago. This makes clustered systems the most common computer architecture represented in the TOP500. This trend is reflected in Gelato’s very active Cluster Performance and Scalability Focus Group, which presented a status report at the recent meetings of the Gelato Strategy Council in Stockholm, Sweden.
