I put the gzip-compressed Postscript version of the manual Parallel Programming with PCN on the Department's FTP site ftp://ftp.cs.olemiss.edu/pub/engr664/ in file pcn_prog_v2.0.ps.gz.
My lectures notes for this class are available as Technical Report UMCIS-1993-04, Notes on Concurrent Programming with PCN. This document is available from the Department's technical report archive (ftp://ftp.cs.olemiss.edu/pub/tech-reports/) in Postscript format.
