Linux continues to dominate the list of the world's fastest supercomputers and there is no reason to think that will change anytime soon.
The latest Top500 supercomputer list reveals that 476 of the fastest machines run some version of Linux, including the top 43 on the list.
The 44th fastest supercomputer, the European Center for Medium-Range Weather Forecasts box, runs IBM's AIX Unix variant. Three supercomputers run Windows, with the fastest being the Magic Cube at the Shanghai Supercomputer Center, at 187th.
The real surprise is that the Tianhe-2 in China came in with more than twice the performance of the top-rated system at the end of November 2012, and did it on Intel chips. Tianhe-2 had a performance of 33.86 petaflop/s on the Linpack benchmark, and is powered by 32,000 of the 12-core Intel Xeon Ivy Bridge processors, and 48,000 Intel Xeon Phi co-processors, with a total system power of 17.8 megawatts. Intel has not held the top spot since 1997. More than 80 percent (403) of the supercomputers use Intel processors.
