PICS Colloquium: “Exploiting time-domain parallelism to accelerate neural network training and PDE constrained optimization” with Eric Cyr

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia

Title: Exploiting time-domain parallelism to accelerate neural network training and PDE constrained optimization Speaker: Eric Cyr, Principal Member of the Technical Staff at the Computer Science Research Institute at Sandia National Laboratories Abstract: This talk will explore methods for accelerating numerical optimization constrained by transient problems using parallelism. Two types of transient problems will be […]

PICS Colloquium: “Physics-compatible kinetic-energy and entropy preserving (KEEP) scheme for high-fidelity simulation of compressible turbulence” with Soshi Kawai

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia

Title: Physics-compatible kinetic-energy and entropy preserving (KEEP) scheme for high-fidelity simulation of compressible turbulence Speaker: Soshi Kawai, Professor of Aerospace Engineering at Tohoku University Abstract: Low (or ideally zero) numerical dissipation is always critical for high-fidelity scale-resolving flow simulations, as numerical dissipation prevents the physics of inviscid kinetic energy and entropy conservation, which is an […]

PICS Colloquium: “Modeling Lone Pair Dynamics in Materials” with Richard Remsing

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia

Title: Modeling Lone Pair Dynamics in Materials Speaker: Richard Remsing, Assistant Professor of Chemistry and Chemical Biology at Rutgers University Abstract: Materials properties are governed by the structure and dynamics of the bonds between their constituent atoms. In addition to covalent, metallic, and ionic interactions that we typically think about, lone pair electrons can result in […]
