Linux powers 9 out of 10 top supercomputers

According to the Top 500 Supercomputer sites, Linux is powering nine of the ten largest supercomputers in the world.

Six of these are running Suse Linux Enterprise Server, Novell is pleased to point out.

According to the Top 500 Supercomputer Sites, around 85 per cent of the top 500 run some blend of Linux, including the top-runner, Jaguar, which is located at the US Department of Energy’s Oak Ridge Leadership Computing Facility. It was upgraded in 2009 and posted a 1.75 petaflops per second performance speed running the Linpack benchmark. Jaguar's theoretical peak capability is 2.3 petaflops per second and consists of nearly a quarter of a million cores.

Holger Dyroff, vice president for Business Development at Novell, said, "Linux has become the HPC operating system of choice, thanks to its scalability and performance capabilities, its similarity to Unix, and the wide variety of open-source software and development tools available."

The TOP500 Project will launch the next Top 500 list at International Supercomputing Conference (ISC) 2010 in Hamburg, Germany, May 30-June 3, 2010.
