Program Composition Notation

(PCN) A specification language for parallelism between C and

Fortran modules. PCN provides a simple language for

specifying concurrent algorithms, 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 supercomputers and integrated debugging and

performance analysis tools. PCN was developed at ArgonneNational Laboratory and the California Institute ofTechnology. 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; multicomputers: iPSC/860, TouchstoneDELTA; and shared memory multiprocessors:

Symmetry/Dynix.
