        (PCN) A specification language for parallelism between {C} and
        {Fortran} {module}s.  PCN provides a simple language for
        specifying {concurrent} {algorithm}s, interfaces to {Fortran}
        and {C}, a portable toolkit that allows applications to be
        developed on a {workstation} or small parallel computer and
        run unchanged on {supercomputer}s and integrated debugging and
        performance analysis tools.  PCN was developed at {Argonne
        National Laboratory} and the {California Institute of
        Technology}.  It has been used to develop a wide variety of
        applications, in areas such as climate modelling, fluid
        dynamics, computational biology, chemistry, and circuit
        simulation.
     
        Version 2.0 runs on networks of workstations: {Sun-4}, {NeXT},
        {RS/6000}, {SGI}; {multicomputer}s: {iPSC}/860, {Touchstone
        DELTA}; and {shared memory} multiprocessors:
        {Symmetry}/{Dynix}.
