NASA to Showcase Computational Achievements at SC13

Nov. 15 — Some of NASA’s best and brightest will showcase more than 30 of the agency’s exciting computational achievements at SC13, the international supercomputing conference, Nov. 17-22, 2013 in Denver.

Highlights include:

  • a summary of supercomputing-assisted science revelations made during NASA’s Mars rover Curiosity’s first year on the Red Planet;
  • the Kepler mission’s new data-centric strategy for continuing the search for Earth-sized planets;
  • unique insights into the physical mechanisms underlying galaxy formation gained through high-resolution 3-D simulations; and
  • computational methods to improve the design of the Space Launch System (SLS) and next-generation launch pad.

Spectacular scientific visualizations from these and other NASA supercomputing applications will appear on a state-of-the art 10-foot-wide hyperwall display.

“NASA’s supercomputing technologies and expertise are key to the success of many missions,” said Rupak Biswas, deputy director of the Exploration Technology Directorate at NASA’s Ames Research Center, Moffett Field, Calif. “This includes expanding our knowledge of the ocean’s role in climate change and the global carbon cycle, understanding how space weather affects technological systems on Earth, and improving the design of aircraft components to reduce the level of noise we are exposed to every day.”

Each day at SC13 Biswas will present a talk on NASA’s new studies to determine the potential for quantum computing to solve difficult problems of importance to the agency. A D-Wave Two quantum computer was installed last summer in Ames’ NASA Advanced Supercomputing (NAS) facility, which also houses the agency’s most powerful supercomputer, Pleiades, an SGI ICE system used to support NASA science and engineering missions. Pleiades recently was expanded to include the newest generation of SGI ICE X systems containing a total of 6,624 Intel Xeon E5-2680v2 (Ivy Bridge) processors (66,240 cores). The expanded system runs at a peak performance rate of 2.87 quadrillion computer operations per second (petaflops).

In addition to Pleiades, the NASA Center for Climate Simulation (NCCS), located at NASA’s Goddard Space Flight Center, Greenbelt, Md., upgraded its Discover supercomputer with the addition of an IBM iDataPlex cluster incorporating 960 Intel Xeon E5-2670 (Sandy Bridge) processors (7,680 cores). Discover now performs at 1.12 petaflops peak.

Using Discover, NASA completed its modeling contributions to the Intergovernmental Panel on Climate Change (IPCC) Working Group I Fifth Assessment Report, released in September 2013. The SC13 exhibit hyperwall will show NASA-produced visualizations of possible 21st century temperature and precipitation pattern changes estimated by dozens of climate models for the IPCC report. Discover is currently hosting a NASA global atmospheric model’s simulation of weather at 7.5-kilometer resolution for two years and 3.5-kilometer resolution for three months. This simulation is expected to generate approximately four petabytes of data.
