IBM dominated the Top500 list of the worlds fastest computers, released in June at the International Supercomputing Conference.
IBMs Blue Gene supercomputers ranked first and second on the list, and IBM systems accounted for 51.8 percent of those on the list. Hewlett-Packard accounted for 26.2 percent, and SGI was third with 5 percent.
“This is a pretty clear indication in terms of IBM dominating the Top500,” said David Turek, vice president of IBMs Deep Computing unit.
IBMs Blue Gene/L system at the federal Lawrence Livermore National Laboratory was again ranked first—it ascended to the top spot in November—but had since been doubled in size. It can now handle 136.8 teraflops, or trillions of calculations per second. Another Blue Gene system, at an IBM research center in Yorktown, N.Y., can handle 91.2 teraflops.
The Top500 list is released twice a year.
