Earthquake Simulation Tops One Quadrillion Flops: Over a petaflop.
Computational Record on SuperMUC 04/15/14 The SuperMUC high-performance computer at the Leibniz Supercomputing Center of the Bavarian Academy of Sciences and Humanities has exceeded the 1 petaflop per second mark. The supercomputer executed 1.09 quadrillion floating point operations per second during an earthquake simulation, and the team of computer scientists, mathematicians, and geophysicists involved in the virtual experiment credit the optimization of the SeisSol software with making it possible. The speed of calculations increased by a factor of five, and the earthquake simulation software maintained this unusually high performance level throughout the entire three-hour simulation run using all of SuperMUC's 147,456 processor cores. The extensive optimization and complete parallelization of the 70,000 lines of SeisSol code allowed a peak performance of up to 1.42 petaflops, which corresponds to 44.5 percent of SuperMUC's theoretical available capacity and makes it one of the most efficient simulation programs of its kind. "Thanks to the extreme performance now achievable, we can run five times as many models or models that are five times as large to achieve significantly more accurate results," says Ludwig Maximilian University's Christian Pelties. "Our simulations are thus inching ever closer to reality."Numerical model to aid in nanophotonic designs 3/14/2013
Researchers from the A*STAR Institute of High Performance Computing have developed a numerical model to simulate the performance of circuits that rely on light. Devices that manipulate photons of light are typically many times larger than conventional circuit components, and this limits their use. In contrast, plasmonic technology promises to overcome the size mismatch between microscale photonics and nanoscale electronics. The numerical model developed by A*STAR researchers could be an invaluable tool for designers in nanophotonics as it can simulate the performance of circuits that rely on light.
