IBM leads Top 500 supercomputer ranking, Linux and Intel dominate list

Mannheim (Germany) - Among the world's top 500 fastest performing supercomputers, an IBM PowerPC 440 model dubbed "BlueGene/L" operated by the US Department of Energy's Lawrence Livermore Laboratories claimed the top spot for the second straight year, the University of Mannheim and its partners revealed today.

IBM PowerPC processors claimed 25 spots on the university's 25th annual Top500 list, including ranks 1, 2 (another BlueGene model operated by IBM's Thomas J. Watson Research Center), 5, 6, 8, and 9. However, Intel dominated the list, claiming 333 of the 500 spots, the university's database shows. Among these, 237 are driven by Xeon processors, the highest performing model in the 20th spot, dubbed "Tungsten," a cluster of 2500 dual-processor Dell PowerEdge 1750 systems running Red Hat Linux. Twenty of the Intel spots were claimed by Itanium systems, the highest ranking being ranked in seventh place, dubbed "Thunder," a 1024 node cluster of Tiger4 1.4 GHz Itanium2 servers, also run by Livermore Labs. Thunder slipped two spots from its fifth position last year
