Developers
Introduction
Bethe–Salpeter Eigenvalue Solver Package (BSEPACK) is a parallel ScaLAPACK-style library for solving the definite Bethe–Salpeter eigenvalue problem of the formand computing the absorption spectrum
where
is Hermitian and positive definite. The library is written in Fortran 90, and targets distributed memory HPC systems.
Download
The latest version (v. 0.1) is available here (Last updated 2016-12-19).
Installation guide
Before building BSEPACK, make sure the following software is installed.
After downloading and unpacking, modify the "make.inc" file according to your system (compiler, linker, libraries, etc.). Then use "make all" to build the library. We refer to the User's Guide for detailed instructions.
