%description
ELPA is a Fortran-based high-performance computational library for the
(massively) parallel solution of symmetric or Hermitian, standard or generalized
eigenvalue problems.

This is the kind of eigenvalue problem which is frequently encountered in
Electronic Structure Theory (solution of Schrödinger's Equation or variants
thereof), but also in many other fields. Typically, the solution effort scales
as O(size^3), where "size" is a measure of the system size, for example the
dimension of the associated matrices or the number of required
eigenvalue/eigenvector pairs (less than or equal to the matrix dimension). Thus,
an algebraically exact solution of the eigenproblem may quickly become the
bottleneck in a practical application.
