Titan: the world’s most powerful supercomputer
The Titan, which is the size of a basketball court and is cooled by an amount of water that would be enough for a small town, is capable of 20 trillion calculations per second, or 20 petaflops. Replaces the Jaguar, former ORNL computer, as it is 10 times more potent.
Titan numbers dizzy. It is made by Cray , XR7 on your system, and has 18,688 nodes. In each of these nodes is a 16-core processor AMD Opteron 6274 (for a total of 299,008 cores) and an NVIDIA Tesla K20. Also has 700 terabytes of memory.
Since graphics cards are designed for simultaneous computation at high speeds are an ideal for supercomputers. They can do much more than the processors in a given time. The 299,008 cores will be responsible for guiding the simulations NVIDIA graphics cards will take care to calculate. This will allow scientists to do the calculations with more speed and accuracy.
One of the key elements in this type of facility is energy consumption. Combining processors and graphics cards in one system can achieve the same performance with lower power consumption. In fact the Titan occupies the same space as the Jaguar and only uses a little more energy.
The Titan mission will be to assist in investigations into energy, climate change, efficient engines, materials and other disciplines and the role is established as the world’s most powerful supercomputer. You will have to exceed 16 petaflops Sequoia , an IBM machine that is at the Lawrence Livermore National Laboratory .
As if this race will not count with enough astronomical numbers, China is already building the Tianhe-2, a machine that is supposed to handle about 100 petaflops and is expected to be ready by 2015.Tags: Supercomputer, Titan
