Tom Papatheodore is an HPC Engineer in the System Acceptance and User Environment group at the Oak Ridge Leadership Computing Facility (OLCF) at Oak Ridge National Laboratory (ORNL). In this role, he develops and runs benchmark applications to verify functionality and performance of OLCF’s pre-production HPC systems, works with OLCF staff and vendor partners to support early-access users of these systems, and manages the pre-production training program for these users. Tom also runs regression tests on user-facing software for the facility’s production supercomputers, helps organize training events related to these systems, and manages the OLCF’s involvement in an annual GPU hackathon series alongside NVIDIA and other partner organizations. He received his PhD in physics from the University of Tennessee in 2015, where he used the OLCF’s Titan supercomputer to simulate explosive nucleosynthesis in the context of Type Ia supernovae using the astrophysics code, FLASH.
