Research Scientist - Computational Science for Large-Scale Simulations

Oak Ridge National Laboratory

Bio: Michael Morgan Wise is a Research Scientist specializing in Computational Science for Large-Scale Simulations at Oak Ridge National Laboratory. Before joining the national lab, Dr. Wise served as a Scientist and Signal Processing Engineer for Dynetics, a Leidos Company, and managed the Electronic Warfare Software Section of the Advanced Technology Development Department in Huntsville, Alabama. He continues to serve as a part-time faculty member for the Electrical and Computer Engineering Department of the University of Alabama in Huntsville, teaching a recurring graduate course in high-performance GPU-accelerated computing as well as occasionally supervising undergraduate research. He received his Ph.D. in Mathematics from the University of Tennessee, specializing in the numerical analysis of partial differential equations under Ohannes Karakashian. His research and development interests, while varied, center on the application of advanced mathematics and high-performance, heterogeneous, and real-time computing concepts to otherwise intractable science and engineering problems.

Talk Abstract:

Improving radio frequency (RF) technologies (e.g., mobile phones, radar, satellites, IoT) requires scientists and engineers to discern and exploit relevant physics. Computational modeling can provide these key insights in cases where necessary experiments are intractable and pen-and-paper calculations are inadequate. However, the computational cost of these models often requires a compromise: one must reduce either the complexity of the scenario or the fidelity of the simulation, as full-resolution simulation of interacting systems can tax even the most capable supercomputers. The recent achievement of exascale computing and the near-term industry goal of zettascale suggest the importance of reassessing what is possible with physics-based simulation, particularly for RF applications. Consequently, the Cosmic Team at Oak Ridge National Laboratory is developing Distributed Analysis of Wireless at Nextscale (Cosmic DAWN), a collection of tools enabling scalable design space exploration and physics-based simulation of RF systems. In this talk, I introduce Cosmic DAWN at a high-level via notional use-cases. I characterize where we are currently and where we intend to go in the near term. Finally, due to the wealth of concepts used under the hood (from, e.g., high-performance computing, applied mathematics, electrical engineering, digital signal processing, AI/ML, and more), I’ll identify research and development opportunities that would benefit the community as it ventures toward nextscale.
