In the latest TOP500 listing, to be released in the next day or so, we will find that nearly half of the top supercomputers in the world are running Novell’s SUSE Linux.
Already announced, the new winner is IBM’s RoadRunner – the first supercomputer to break the ‘mythical’ 1 TFop/s barrier. At a recent benchmark, it achieved 1.026 TFop/s on the Linpack benchmark. The OS is yet to be confirmed, but pretty-much every other IBM computer in the list is running a version of SUSE. I’ll be guessing much the same as you!
Assuming the remainder of the list looks a lot like the previous list (November 2007), running second and third, we find a couple of IBM Blue Gene systems, then SGI and Hewlett Packard get a look in.
