Professor Scott Hughes will discuss recent work modeling gravitational wave sources using large-scale parallel computing. His research focuses on solving complex differential equations that describe astrophysical phenomena responsible for generating gravitational waves, such as extreme mass ratio inspirals and other compact object systems. These calculations require an enormous number of repeated computations—on the order of hundreds of millions of equation solves—which are addressed by leveraging highly distributed, high-throughput computing resources. Professor Hughes will describe how the subMIT platform and the Open Science Grid (OSG) have enabled his team to dramatically accelerate these computations, reducing run times from months to days. The talk will cover the astrophysical motivation for this work, the computational challenges involved, and how scalable workflows and parallelization strategies are advancing this research. He will also outline current efforts and future plans to further optimize workflows for even more demanding simulations.
