Oak Ridge Staff Members Participate in Extreme Computing Workshop

Tags: ,

Talks focus on computer science using next-generation supercomputers

Five Oak Ridge National Laboratory staffers presented at the Institute for Nuclear Theory’s (INT’s) workshop, “The Nuclear Physics/Applied Math/Computer Science Interface,” held June 27 through July 1 at the University of Washington. The workshop brought together computational scientists, applied mathematicians, and nuclear physicists for five days of presentations, discussions, and work groups.

Oak Ridge staff spoke in the areas of performance, solving algebraic systems, and architectures/programming languages and graphics processing units:

  • Richard Graham: “Preparing Applications for Ultrascale Computing: A Tools Perspective.”
  • Scott Klasky: “In Situ Data Processing for Extreme Scale Computing.”
  • Tony Mezzacappa: “Supernova Simulations.”
  • Jeffrey Vetter: “Large-Scale Heterogeneous Computing.”
  • Bronson Messer: “Producing Science at the Top of the Top500 – The Challenge of Extreme Scalability and Hybrid-Multticore Computing.”

“Those at the workshop are consistently among those making capability use of leadership computational resources,” said Messer, a computational astrophysicist. “The meetings allowed practitioners of fundamental science on big DOE machines to share what we all do the same and what common problems we have. If we can suss out those problems, it will benefit everyone who does large scale computing.”

The INT receives Department of Energy Office of Science funding to run both short workshops and months-long programs. –by Sandra Allen McLean
