The Fastest Supercomputer is Also One of the Greenest

Nov. 16, 2012 ⋅ Categories: Infrastructure

The Fastest Supercomputer: Oak Ridge Nation Laboratory’s supercomputer, Titan, is considered the most powerful of all high-performance computers. Surprisingly, it is also one of the most energy efficient. Ranking as number three on the Green500 list , the exciting news was announced Wednesday, November 14. The position on the list is reflective of the significant power saving attributes to Titan’s hybrid architecture that evolved from combining graphics processing units (GPUs) from gaming systems and traditional CPUs.

The system has 18,688 nodes that each has a 16-core AMD Opteron 6274 processor and an NVIDIA Tesla K20X GPU accelerator. This is only on top of its 700 terabytes of memory storage. The hardware itself is pretty intense and can handle hundreds of calculations simultaneously by relying on 299,008 CPU cores. These cores guide simulations, allowing its NVIDIA GPUs to do some heavy lifting.

Titan is sure to help the super-charged workstation enthusiasts by letting them complete their work with greater speed and accuracy. We, at PSSC labs, are especially happy to see that a greener way of doing business is setting the bar for the future of supercomputers.
