On Oct. 29th the U.S. Department for Energy's Oak Ridge National Laboratory aims begin operations of the Cray XK7 "Titan" System - expected to be the world's fasted supercomputer which promises a speed reaching 20 petaflops or 20 quadrillion calculations per second.
The current world record 16.32 petaflops is held by Sequoia , according to the Top500 supercomputer list. The key to Titan's speed will be the hybrid Linux combination of 16-core AMD Operon CPUs and Nvidia Kepler GPUs to overcome space and power limitations of existing supercomputers.
The Titan system is a 200-cabinet Cray XK7 supercomputer.
Titan contains 299,008 CPU cores and 18,688 GPUs to guide simulations and allow its Kepler GPUs to do the hard work. Titan will contain 700 terabytes of memory.
Titan will take up the same space as its predecessor, Jaguar and is expected to be about ten times more powerful. Titan will also draw abou the same amount of power as Jaguar.
Titan will be used to study climate change, nuclear energy, radiation transport, combustion, membrane fusion, nanoscale materials and more.
