Speeding Climate Simulations

Oct 28, 2014 |

As highlighted in a recent issue of DOE Pulse, which features science and technology news from the DOE National Labs, scientists from Pacific Northwest National Laboratory (PNNL) have developed a more efficient way to perform computationally expensive global climate simulations. As climate models become more precise and detailed, the simulation takes more time, putting pressure Read more…

Evolving Exascale Applications Via Graphs

Apr 29, 2014 |

There is little point to building expensive exaflop-class computing machines if applications are not available to exploit the tremendous scale and parallelism. Consider that exaflop-class supercomputers will exhibit billion-way parallelism, and that calculations will be restricted by energy consumption, heat generation, and data movement. This level of complexity is sufficient to stymy application development, which Read more…

A Small Company Builds a Big Supercomputer

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/atipa_cloud_150x.jpg” alt=”” width=”95″ height=”88″ />Atipa Technologies, a small privately-held division of PC and server maker Microtech Computers, has just sold a $17 million, 3.4 petaflops supercomputer to the Environmental Molecular Sciences Laboratory (EMSL), a DOE government research lab. It’s a coup – for Atipa, CPU accelerators and Xeon Phi.
