Beyond Tianhe-2 #HPC #ISC14 #Top500 via @IEEESpectrum @NERSC

The TOP500 semi-annual ranking of the world’s most powerful supercomputers, announced yesterday, revealed that China’s Tianhe-2 has kept its first-place position. The three-time winner, capable of performing 33.86 petaflops (a maximum of 33.86 quadrillion computations per second) remains nearly twice as fast as its nearest competitor, the Titan supercomputer at Oak Ridge National Laboratory. The TOP500 ranking is based on contenders’ performance running the LINPACK Benchmarks, which measure how fast a computer can solve large systems of linear equations. While this is a convenient way to rank computer performance, it doesn’t reflect all the tasks supercomputers might be faced with. In particular, some have to analyze and process huge datasets, meaning that it’s more valuable for them to be able to quickly determine the connections between data points than to perform numeri...
