You know that there is a ranking of the Top 500 fastest supercomputers? The "K" supercomputer lead the ranking according to the list published June 2011, when the "K" achieved a speed of 8.162 petaflops. This week its operators, Fujitsu and Riken, informed the supercomputer broke its own record hitting 10 quadrillion calculations per second. Not bad.

Supercomputers are used for highly calculation-intensive tasks such as problems including quantum physics, weather forecasting, climate research, molecular modeling and physical simulations.

The system is still under construction and is scheduled to enter full service in November 2012 with 864 cabinets, comprising a total of 88,128 interconnected CPUs (SPARC64 VIIIfx processors) and has a theoretical calculation speed of 11.28 petaflops.

And if you enjoy the OS war... more than 90% of today's Supercomputers run some variant of Linux, and "K" isn't the exception, running a Linux-based enhanced operating system.
