I've been tracking the Top500 Supercomputer List with a particular eye on Linux for some time now, highlighting how Linux continues to power the majority of the world's fastest supercomputing systems. So it's no surprise to see continued dominance for Linux, but there are some interesting changes every six months when the new fastest supercomputer system list comes out. The most recent list, released last month, reinforces Linux leadership, as every single one of the top 10 fastest supercomputing systems in the world runs Linux.
