Turing : The PARPACK library


PARPACK (Parallel ARnoldi PACKage) is a parallel version of the ARPACK software. ARPACK is a package of Fortran 77 subroutines which implement the Implicitly Restarted Arnoldi Method used for solving large scale eigenvalue problems. PARPACK is portable across a wide range of parallel platforms and requires minimal changes to the serial code. The communication layers used for message passing are the Basic Linear Algebra Communication Subprograms (BLACS) developed for the ScaLAPACK project and Message Passing Interface (MPI).
