.SH NAME 
p4 - portable programs for parallel processors - release 1.4

.SH DESCRIPTION
p4 is a package of procedures that support development of parallel programs in
C or Fortran that are portable across a wide variety of architectures.  For
the shared-memory model of parallel computation, p4 provides a set of
primitives from which monitors can be constructed, as well as a set of useful
monitors.  For the distributed-memory model, p4 provides typed send and
receive operations, and creation of processes according to a text file
describing files to be executed on by created processes and the machines to
execute them on.  A complete User's Guide is available in the doc subdirectory
of the p4 distribution.  It is written in LaTeXinfo, so that it can produce
either an info file (included) or a printed version.
