PCWorld: After receiving 19,584 more CPUs in an upgrade, the world’s fastest supercomputer, known as “K,” set a new record: 10.51 petaflops. Owned by Fujitsu and RIKEN, K also held the previous record of 8.162 petaflops, which was set in June of this year.
If you add up the computing power of the seven next fastest supercomputers, the total comes to 9.974 petaflops, meaning that K is faster than its seven closest competitors combined.
In all, K has 88,128 SPARC64 VIIIfx CPUs across 864 computing racks.
