The Parallel Iterative Methods (PIM) package for the solution of systems of linear equations on parallel computers Original Research Article

We present a collection of public-domain Fortran 77 routines for the solution of systems of linear equations using a variety of iterative methods. The routines implement methods which have been modified for their efficient use on parallel architectures with either shared or distributed memory. PIM was designed to be portable across different machines. Results are presented for a variety of parallel computers.
