The Oak Ridge National Laboratory ( ORNL ) in Tennessee has its supercomputer “Titan” commissioned. He is considered the world’s fastest computer for public science applications. The peak performance of over 20 petaflops, or more than 20 quadrillion floating point operations per second. Thus, Titan is about ten times faster than its predecessor “Jaguar” which came with the same size at 2.3 petaflops. Titan works simultaneously with an energy consumption of 9 megawatts, five times more fuel efficient.
The new system is based on a Cray XK7 with 18,688 nodes, each of which consists of a 16-core Opteron 6274 CPU from AMD and a Tesla GPU from Nvidia with K20 Kepler architecture. It also provides more than 700 terabytes of storage.
Titan is in the Oak Ridge National Laboratory, part of the Research Network of the U.S. Department of Energy, operated as an open-system science. It has helped researchers from universities, government laboratories and companies to model physical and biological phenomena. To major research projects include the development of commercially viable biofuels, clean combustion engines, advanced nuclear energy and solar energy more efficiently. Other possible applications include materials science, climate research and astrophysics.
“Science and technology have always been our top priority and Titan is a revolutionary tool that is accessible worldwide on the researchers to achieve by the GPU-accelerated computing breakthroughs in various fields,” Jeff Nichols, associate laboratory director, said for Computing and Computational Sciences at Oak Ridge National Laboratory. “The combination of GPUs and CPUs in a single system less power than CPUs alone is needed. It is a responsible step to improve our CO2 footprint. “The new Tesla GPUs would offer unmatched performance, without taking the energy consumption of a small town in need purchase. They provided about 90 percent of the computing power.
The development of titanium began three years ago with the decision of ORNL to upgrade the former leading supercomputer Jaguar. If they had only swapped the CPUs to achieve the same performance, it would now occupy more than four times its current size and consume more than 30 megawatts.
For the official launch of the Department of Energy Titanium 4.7 billion supercomputing hours in Oak Ridge and another facility as part of its program Novel Computational Impact on Theory and Experiment (INCITE) has made available. Because 61 participating academic and research projects, “to accelerate high-potential, knowledge and innovation”.
Built by Cray system competes directly with the according to the current Top 500 list of the fastest supercomputers in the world, the “Sequoia” based on IBM’s Blue Gene / Q. He is in the Lawrence Livermore National Laboratory of the U.S. Department of Energy and reached its 1,572,864 cores peak performance of 20.13 petaflops. In control mode manages to 16.32 petaflops. Titans predecessor Jaguar took the top of the top 500 list in 2009 and defended it for about one year before the Chinese system “Tianhe-1A” filed past , which is also based in large part on GPUs from Nvidia.
