IBM's Roadrunner sets new supercomputer record using Red Hat

iTWire: A hybrid supercomputer built by IBM for the UD Department of Energy's National Nuclear Security Administration more than doubles the speed of Blue Gene, previously the world's fastest. And it does so with the aid of the processor used in the Sony PlayStation 3.
The hybrid tag refers to the way Roadrunner was designed to exploit the strengths of the Cell Broadband Engine as well as conventional x86 chips from AMD. This is said to be a first in supercomputer design.
Roadrunner features 12,960 Cell chips along with 6948 dual-core Opteron CPUs. Assembled from off-the-shelf IBM blade servers, the system is housed in 288 "refrigerator sized" racks.
