Topic: Windows Cluster Hits a Petaflop, But Linux Retains Top-5 Spot

[sam]

Microsoft says a Windows-based supercomputer has broken the petaflop speed barrier, but the achievement is not being recognized  by the group that tracks the world's fastest supercomputers, because the same machine was able to achieve higher speeds using Linux. The Tokyo-based Tsubame 2.0 computer, which uses both Windows and Linux, was ranked fourth in the world in the latest Top 500 supercomputers list. While the computer broke a petaflop with both operating systems, it achieved a faster score with Linux, denying Microsoft its first official petaflop ranking.
