ARMONK, NY – IBM’s supercomputing system at Los Alamos National Laboratory in California still ranks as the fastest supercomputer in the world–but just barely.

Biannual rankings by U.S. and German researcherers clocked the IBM Roadrunner system at 1.105 petaflops. A petaflop equals 1 quadrillion calculations a second.

Cray’s (Nasdaq:CRAY)Jaguar system at Oak Ridge National Laboratory in Tennessee runs at 1.050 petaflops.

IBM says one of its systems has been the world’s most powerful computer since November 1999.

IBM employs about 11,000 people in the North Carolina Research Triangle. According to reports in WRAL’s Local Tech Wire, the company will lay off 38 people at its RTP facility as part of a wider company “resource reduction.”
