Researchers Introduce 22.8 TFlop Energy-Efficient Supercomputer


Researchers at Virginia Tech’s Center for High-End Computing Systems have built the second version of a supercomputer called System G that runs at 22.8 TFlops. System G uses 325 Mac Pro computers that each have two four-core 2.8 GHz Intel Xeon processors and eight GB of RAM.

Best of all, the machine is an experiment in green computing. System G is the largest power-aware cluster in the world, and will help researchers develop algorithms for high-performance computer requiring minimal power.

System G is decked out with power-aware disks, CPU’s, and memory. It is also the most advanced network of power and thermal sensors to be assembled on such a machine.

Ultimately, the researchers hope to use System G to create energy-efficient computing systems as small as department-sized machines and as large as national-scale resources.
