Title: Machine learning potentials with ab initio accuracy in extreme scale environments
Abstract
With the availability of large amounts
of computing power provided by distributed memory computers, hardware
accelerators, and large datasets of quantum chemistry data, it has become
possible to deploy accurate machine learning models that accelerate chemical
discovery. These models achieve ab initio accuracy in a fraction of the
computational cost. In this talk, I will discuss experiences using machine
learning potentials (MLPs) as surrogate models to accelerate molecular
dynamics simulations that study the thermodynamic properties of materials,
specifically molten salts and 2D materials. I will cover the process of
generating accurate data, distilling, training MLPs, and performing
molecular dynamics at scale.
