  5. 5. Parallel Algorithms and Library Software for the Generalized Eigenvalue Problem on Distributed Memory Computer Systems

    University dissertation from Umeå : Umeå universitet

    Author : Björn Adlerborn; Umeå universitet.; Umeå universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; data- och systemvetenskap; Computer and Information Science;

    Abstract : We present and discuss algorithms and library software for solving the generalized non-symmetric eigenvalue problem (GNEP) on high performance computing (HPC) platforms with distributed memory. Such problems occur frequently in computational science and engineering, and our contributions make it possible to solve GNEPs fast and accurate in parallel using state-of-the-art HPC systems.
