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.

Astronomers Erika Nesvold (UMBC) and Marc Kuchner (NASA Goddard) essentially created a virtual Beta Pictoris in the computer and watched it evolve over millions of years. It is the first full 3-D model of a debris disk where scientists can watch the development of asymmetric features formed by planets, like warps and eccentric rings, and also track collisions among the particles at the same time.

Supercomputing the Interior Dynamics of Stars and Giant Exoplanets

Simulations like these help researchers better understand the interior dynamics of these planets and learn more about how they may have formed. Magenta indicates magnetic fields with positive polarity, and blue indicates fields with negative polarity. Tamara Rogers, Jess Vriesema, University of Arizona

Over at the NASA Ames Research Center, Michelle Moyer writes that the agency is using supercomputer simulations to explore the interior dynamics of stars and giant exoplanets.
