Oak Ridge National Laboratory has received funding from a federal project to develop applications for more powerful supercomputers, systems that could be 50 to 100 times more powerful than today’s fastest supercomputers.

The project is the U.S. Department of Energy’s Exascale Computing Project, or ECP. It’s to develop applications for future exascale systems. Exascale refers to high-performance computing systems capable of at least a billion billion calculations per second, which is up to 100 times faster than the nation’s most powerful supercomputers in use today, a press release said.

The work on applications will help guide DOE’s development of a U.S. exascale ecosystem as part of President Barack Obama’s National Strategic Computing Initiative, or NSCI, the press release said.

The first round of ECP funding totals $39.8 million for 22 proposals representing teams from 45 research and academic organizations. ORNL researchers and technical staff will participate in 12 of the 22 projects.

The awards, announced Wedneday, target advanced modeling and simulation solutions to specific challenges supporting key DOE missions in science, clean energy, and national security, as well as collaborations such as the Precision Medicine Initiative with the National Institutes of Health’s National Cancer Institute, the press release said.

Test run signals emergence of the next generation in nuclear power reactor analysis tools

Scientists and engineers developing more accurate approaches to analyzing nuclear power reactors have successfully tested a new suite of computer codes that closely model “neutronics”—the behavior of neutrons in a reactor core.

Technical staff at Westinghouse Electric Company LLC, supported by the research team at the Consortium for Advanced Simulation of Light Water Reactors, or CASL, used the Virtual Environment for Reactor Applications core simulator (VERA-CS) to analyze its AP1000 advanced pressurized water reactor. The testing focused on modeling the startup conditions of the AP1000 plant design. [Read more…]
