Paul Fischer is a professor in the departments of Computer Science and Mechanical Science and Engineering at the University of Illinois, Urbana Champaign, and a senior scientist at Argonne National Laboratory. He has pioneered the development of spectral element methods for high-performance simulations of turbulence, including the development of Nekton 2.0, which was the first commercial software for distributed-memory parallel computers. The research variant, Nek5000, is a prior Gordon Bell winner and has scaled to millions of ranks on Mira and Sequoia. It is used by over 500 researchers in industry and academia. Fischer's current research is focused on advanced preconditioners for GPU-based solutions of PDEs, reduced-order models for turbulent flows with applications to industrial problems, and exascale computing.
