We are accepting applications to attend our 2018 Workshop “Solving or Circumventing Eigenvalue Problems in Electronic Structure Theory,” held in collaboration with MolSSI, from August 15-17, 2018 in Richmond, VA, USA. More information may be found at the conference website. We hope to see you there!
ELSI provides and enhances scalable, open-source software library solutions for electronic structure calculations in materials science, condensed matter physics, chemistry, molecular biochemistry, and many other fields. ELSI focuses on methods that solve or circumvent the Kohn-Sham eigenvalue problem in density-functional theory. The ELSI infrastructure should also be useful for other challenging eigenvalue problems.
One of the key design pillars of ELSI is portability and support for various computing environments, from laptop-type computers all the way to the most efficient massively parallel supercomputers and new architectures (GPU and manycore processors).
The libraries supported and enhanced in ELSI are:
- ELPA (the Eigenvalue soLvers for Petaflop-Applications)
- libOMM (the Orbital Minimization Method)
- PEXSI (the Pole EXpansion and Selected Inversion method)
- SLEPc-SIPs (the SLEPc Shift-and-Invert Parallel Spectral transformations eigensolver)
Work is in progress to support additional solver libraries, providing electronic structure codes and users with a flexible, customizable choice of solutions for the central algebraic problems that are often the bottleneck of large-scale Kohn-Sham DFT simulations.
