Parallel Generalized Real Symmetric-Definite Eigenvalue Problem
James S. Sims, María Belén Ruiz · Journal of Research of the National Institute of Standards and Technology · 2020
A computationally fast Fortran 90+ quadruple precision portable parallel GRSDEP (generalized real symmetric-definite eigenvalue problem) package suitable for large (80,000 x 80,000 or greater) dense matrices is discussed in this paper.
