## About This Manual

This publication documents the Message Passing Toolkit for IRIX (MPT) 1.5 implementation of PVM-3 supported on SGI MIPS based systems running IRIX release 6.5 or later. No technical changes have been made for MPT 1.5.

This implementation of PVM-3 is based on the public domain PVM product, version 3.3.10, developed by researchers at the Oak Ridge National Laboratory (ORNL), the University of Tennessee (UT), and Emory University (EU). It consists of a PVM library and several commands that support PVM.
