PCN [#fosterpcnapproach##1#,#fosterpcnmanual##1#] is a system for developing and
executing parallel programs.
It comprises a high-level programming language, tools for developing
and debugging programs in this language, and interfaces to Fortran and
C that allow the reuse of existing code in multilingual parallel
programs.
The network version of PCN (net-PCN) was ported to the SP1.
Runtime support was added to PCN to allow communication to use
TCP/IP over either the switch or the ethernet.
Several PCN applications were run on the SP1, including the
Massively Parallel Mesoscale Model (MPMM).
