Titan - Supercomputing system utilizes a hybrid architecture

The combination of CPUs and GPUs will allow Titan and future systems to overcome power and space limitations inherent in previous generations of high-performance computers.

Because they handle hundreds of calculations simultaneously, GPUs can go through many more than CPUs in a given time. Yet they draw only modestly more electricity. By relying on its 299,008 CPU cores to guide simulations and allowing its Tesla K20 GPUs, which are based on NVIDIA's next-generation Kepler architecture to do the heavy lifting, Titan will be approximately ten times more powerful than its predecessor, Jaguar, while occupying the same space and drawing essentially the same level of power.

When complete, Titan will have a theoretical peak performance of more than 20 petaflops, or more than 20,000 trillion calculations per second. This will enable researchers across the scientific arena, from materials to climate change to astrophysics, to acquire unparalleled accuracy in their simulations and achieve research breakthroughs more rapidly than ever before.
