<title>NIST Parallel Applications Development Environment (PADE)
<title_line>to facilitate development of parallel applications for heterogeneous networked computers
<abstract>
Strategy: Provides a single graphical user interface that incorporates all
essential tools for development of parallel applications. The model is an
extension of that of standard Unix-based development for a single
processor.

Implementation: PADE can employ any standard message-passing library
for interprocessor communications. Its main purpose is to facilitate
development on a heterogeneous network, so the current version utilizes
the PVM message passing library, a public domain application available for
most Unix systems. It provides a graphical user interface that runs on the
user's development host, which provides all utilities for development and
maintenance of programs that run on nodes of the user's virtual machine.

<environment>
System requirements: To run PADE 1.4, the development host must
support: 

     PVM version 3.0 or higher 
     X windows 
     The Tcl/Tk (7.4/4.0) windowing environment. PADE 1.2 runs under
     Tcl/Tk (7.3/3.6) and is incompatible with Tcl/Tk (7.4/4.0). 

The nodes of the virtual machine need only support PVM version 3.0 or
higher.
