Colloquium Year: FALL 2025

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Jimmie Adriazola, Arizona State University ABSTRACT: In the first part of this talk, we introduce an operator learning framework for computer-assisted discovery of integrability in Hamiltonian dynamical systems. Integrablity is a mathematically rich topic and often the starting point for analyzing more complex, nonintegrable equations. However, it is […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Damian Rouson, Lawrence Berkeley National Laboratory ABSTRACT: The vast majority of parallel programs running on high-performance computing (HPC) platforms leverage parallel programming models often referred to as “MPI+X”, where MPI is the Message-Passing Interface and X typically stands for OpenMP, OpenACC, or CUDA. Over the course of the […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Scott Mitchell, Sandia National Laboratory, Center for Computing Research ABSTRACT: I’ll describe my family’s colorful journey leading me to Sandia Labs, and what it’s like to work there and with the international research community. I’ll highlight some key technical concepts from triangulations and meshing, and how my work […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Miguel Dumett, San Diego State University, Computational Science Research Center ABSTRACT: Mimetic differences is a numerical method for constructing schemes that can solve partial differential equations. The method is derived from a high-order approximation of the integration by parts and uses a staggered grid. It offers uniform accuracy over […]
