Ethernet Enlarges Supercomputing

Gigabit Ethernet is now the network of choice in more than half of the world's top supercomputing sites, and InfiniBand's popularity is rising.

The list of the world's Top 500 supercomputers was unveiled today at the 21st International Supercomputer Conference in Dresden, Germany. It shows that gigabit Ethernet is the interconnect for 256 (51.2 percent) of the world's top supercomputing sites, up from 212 (42.4 percent) one year ago. (See High-Speed Links Favor Ethernet.)

Installations of InfiniBand, still the third-favorite Top 500 interconnect, have doubled since last June. Thirty-five (7 percent) of the Top 500 now use it, compared with 16 (3.2 percent) last year.

Meanwhile, installations of Myrinet, a packet-switching technology sold by Myricom Inc., have plummeted. While still the second-place choice, only 54 (10.8 percent) of the Top 500 sites use Myrinet, compared with 141 sites, or 28.2 percent, last year. (More on that momentarily.)
