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.
