Open source software for solving large-scale generalized eigenvalue problems on distributed computers. Suitable for large (80,000 by 80,000 or greater) dense matrices. Written in Fortran90+. Includes a test program and sample output. In particular, this distribution, MPI_GEVP_Package.tar.gz, consists of documentation (HowTo_MPI_GEVP_inviter.pdf), a collection of output files, and the software distribution itself. To use the software, download MPI_GEVP_package.tar.gz, unwrap it, and follow the instructions in the HowTo to compile the solver and another program for generating test matrix elements. Then run various tests and compare the results with the output found in the various Output files.
