The file report.ps contains the CSRI technical report: Experiences with the Orca Programming Language by Gregory V. Wilson (CSRI, University of Toronto) Henri E. Bal (Dept. of Mathematics and Computer Science, Vrije Universiteit) If you have the UNIX uncompress program, get the report.ps.Z file. Remember to transfer the file in binary mode. Uncompress it, and print it on a postscript printer. If you do not have uncompress, get the report.ps file in ascii mode, and print it on a postscript printer. This report was made available for anonymous ftp by: gvw@csri.toronto.edu ABSTRACT We investigate the capabilities and shortcomings of Orca, a Modula-like parallel programming language supporting shared data objects on distributed memory platforms, by examining implementations of five non-trivial parallel applications: game tree searching, active chart parsing, image skeletonization, simulation of a chaotic predator/prey system, and polygon overlay.
