Abstract

This seminar will give a background of Exascale computing at ORNL including its current status and plans for the future. A general overview of the Exascale Computing Project (ECP) will be presented along with lessons learned and experiences with using Frontier and AMD. Details of the current status of the nuclear energy focused ExaSMR project under ECP will also be presented. Finally, the seminar will conclude with details of new features available and being implemented in the ORNL Shift Monte Carlo code targeted at HPC.

Biography

Dr. Thomas Evans is currently the Group Leader of the High Performance Computing Methods for Nuclear Applications group at Oak Ridge National Laboratory. He received a BS degree in Physics and Astronomy from Haverford College in 1992. He then received an MSHP in 1994 and a Ph.D. in Nuclear Engineering from Georgia Institute of Technology in 1997. Dr. Evans worked as a Technical Staff Member in the Radiation Transport Group at Los Alamos National Laboratory from 1997 – 2007 before joining ORNL. Dr. Evans has over 100 publications in the general area of numerical modeling and simulation with a particular emphasis on radiation transport, linear and nonlinear solvers, algorithms and methods for high performance computing, and coupled physics. Dr. Tara M. Pandya is the Group Leader of the Radiation Transport group at Oak Ridge National Laboratory. She received her B.S., M.S., and Ph.D. degrees in Nuclear Engineering from Texas A&M University in 2006, 2009, and 2012 respectively. She joined ORNL in 2012 as a Postdoctoral Researcher and transitioned to R&D Associate Staff in 2014 in the Radiation Transport group. Her research interests include Monte Carlo, deterministic, and hybrid radiation transport methods and code development aimed toward nuclear applications. Dr. Pandya has been a member of the American Nuclear Society since 2002 and currently serves as the Chair of the Mathematics and Computation Division.
