'''Program Composition Notation''' ('''PCN''') is a specification notation for building up larger programs from smaller modules or programs (usually written in [[C (programming language)|C]] or [[Fortran]]). Efficient parallel programming is at the heart of PCN. Larger composed programs are intended to execute efficiently on single-processor machines, [[multiprocessor]]s with shared memory or distributed multicomputers.<br />
<br />
PCN was developed at [[Argonne National Laboratory]] and the [[California Institute of Technology]].<br />
<br />
PCN includes the language for specifying concurrent algorithms and interfaces to [[C (programming language)|C]] and [[Fortran]]. There is also a PCN toolkit for workstations that allows applications to be developed for supercomputers which includes debugging and performance analysis tools.<br />
<br />
PCN is appropriate for applications benefiting from [[parallel computing]] such as [[fluid dynamics]], and [[climate modelling]].<br />
