The US Department of Energy’s (DOE) Oak Ridge National Laboratory (OR) has introduced a new supercomputer, called Titan, which is capable of running over 20 petaflops per second using a series of upgraded AMD processors and Nvidia GPUs.
The new supercomputer has 18,688 nodes, with each having a 16 core AMD Opteron 6274 processor and an Nvidia Tesla K20 GPU.
Titan, which has over 700 terabytes of memory, will be used for calculations relating to research in energy, climate change, efficient engines, materials and other disciplines.
According to ORNL, the combination of central processing units, the traditional foundation of high-performance computers, and more recent GPUs will allow Titan to occupy the same space as its Jaguar predecessor while using only marginally more electricity.
According to ORNL, using a grid of 14km cells, the new system will be able to simulate from one to five years per day of computing time, up from the three months or so that Jaguar was able to churn through in a day.
