PDS is a collection of Fortran subroutines for solving
unconstrained nonlinear optimization problems using direct search
methods. The software is written so that execution on sequential
machines in straightforward while execution on Intel distributed
memory machines can be accomplished simply by including a few well-defined
routines containing calls to Intel-specific Fortran libraries.
