Shifts in the Top 500 Supercomputer List
There have been a few changes in the Top500 list of supercomputers after a Cray XT5 supercomputer called "Jaguar" finally wrestled the number one spot away from IBM’s "Roadrunner."
Just as the last time the list was released, the Top500 list is made up mostly of Hewlett-Packard and IBM computers. HP accounted for 210 of this year's 500, and IBM 185. In terms of processors in use, Intel still enjoys the lion's share, with 80 percent. The most popular operating system is Linux, with 90 percent of the Top500.
