Pleiades Supercomputer Moves Up the Ranks with Haswell

Pleiades_two_row_small

NASA reports that it’s newly upgraded Pleiades supercomputer ranks number 11 on the July 2015 TOP500 list of the most powerful supercomputers. And while the LINPACK computing power of Pleiades jumped nearly 21 percent, its ranking at number 5 on the new HPCG benchmark list reflects its ability to tackle real world applications.

Argonne Names Distinguished Fellows for 2015

Atos, the multinational digital services company, has signed a contract with the French Alternative Energies and Atomic Energy Commission, the CEA, to supply Tera1000, a 25 Petaflop Bull supercomputer intended as a forerunner to Exaflop supercomputing by the end of 2020.

New UCX Network Communication Framework for Next-Gen Programming Models

UCX

UCX is a collaboration between industry, laboratories, and academia to create an open-source production grade communication framework for HPC applications. “The path to Exascale, in addition to many other challenges, requires programming models where communications and computations unfold together, collaborating instead of competing for the underlying resources. In such an environment, providing holistic access to the hardware is a major component of any programming model or communication library. With UCX, we have the opportunity to provide not only a vehicle for production quality software, but also a low-level research infrastructure for more flexible and portable support for the Exascale-ready programming models.”

IBM and NVIDIA Launch Centers of Excellence at ORNL and LLNL

openpower

Today IBM along with Nvidia and two U.S. Department of Energy National Laboratories today announced a pair of Centers of Excellence for supercomputing – one at the Lawrence Livermore National Laboratory and the other at the Oak Ridge National Laboratory. The collaborations are in support of IBM’s supercomputing contract with the U.S. Department of Energy. They will enable advanced, large-scale scientific and engineering applications both for supporting DOE missions, and for the Summit and Sierra supercomputer systems to be delivered respectively to Oak Ridge and Lawrence Livermore in 2017 and to be operational in 2018.

Dynamically Downscaling Climate Models

Jim Collins writes that a research team from Argonne National Laboratory and the University of Chicago is using the Mira supercomputer to investigate the effectiveness of dynamically downscaled climate models. :We are now able to submit several simulations at one time, which allows us run simulations two to four times faster than before.”

Radio Free HPC Looks at Supercomputing Global Flood Maps

In this podcast, the Radio Free HPC team looks at how the KatRisk startup is using GPUs on the Titan supercomputer to calculate global flood maps. “KatRisk develops event-based probabilistic models to quantify portfolio aggregate losses and exceeding probability curves. Their goal is to develop models that fully correlate all sources of flood loss including explicit consideration of tropical cyclone rainfall and storm surge.”

CEA Teams With Atos to Develop Exaflop Supercomputer
