Accelerating finite-element-based projector augmented-wave density functional theory calculations with scalable GPU-centric computational methods
This paper presents a scalable, GPU-centric finite-element projector augmented-wave (PAW-FE) method that leverages algorithmic innovations like mixed-precision arithmetic and Chebyshev filtered subspace iteration to achieve significant speedups and exascale-ready performance for large-scale, chemically accurate density functional theory simulations.
