ELPA-AEO: improvements to the eigensolver targetting electronic-structure theory — Andreas Marek1, Hermann Lederer1, Christian Carbogno2, Matthias Scheffler2, Lydia Nemec3, •Christoph Scheurer3, and Karsten Reuter3 — 1MPCDF, MPG, Garching — 2Fritz-Haber Institut, MPG, Berlin — 3Theoretical Chemistry, TUM, Garching
ELPA is a leading state-of-the-art library of massively parallel, highly scalable direct eigensolver routines.[1,2] It is heavily used by many application programs, e.g. from electronic-structure theory, such as FHI-aims, VASP, Quantum Espresso, or CP2K.
The ongoing ELPA-AEO project (BMBF 01IH15001) joins groups from numerical mathematics, computer science, high-performance computing, electronic structure theory, and theoretical chemistry and physics to develop algorithmic extensions and optimizations with an impact at the application level.[3] In this contribution we report on recent achievements and changes to the library. Application-level showcases with the electronic-structure code FHI-aims are presented and an outlook on new functionality is given.
