PADE unpacks into a directory structure consisting of the top directory (entitled nist_pade ) and four subdirectories: pade , caml_utils , pade_doc , and examples .

The top nist_pade directory contains the following four (ASCII) files.

• RELEASE-NOTES -- this file describes any changes or additions to the PADE package that did not make it into this manual, changes since the previous version, known bugs, etc.

• INSTALL -- a brief guide to installation of the PADE package.

• MANIFEST -- a complete listing of all files that should be found in the package.

• CHECKLIST -- check lists for the actions performed during installation and user set up.

1. PADE Interface -- A set of Tcl/Tk scripts that together implement the graphical user environment of PADE. These scripts are contained in the pade subdirectory.

2. CAML Utilities -- There are four utilities in the caml_utils

   subdirectory:

   • PVMmake provides both the file transfer and command execution capabilities of PADE.
   • pvmstat returns information about the status of the user's virtual machine, whether PVM has been started, and the current configuration of the virtual machine.
   • pvmtidy enables the user to clean up hopelessly lost PVM daemons and user processes after PVM is halted ungracefully.
   • padeinituser enables PADE users to create the default directory tree in which PVM binaries are located and to place the NIST CAML utilities in their proper places.

3. The PADE User's Manual and The PADE Installation Guide -- These documents are provided in both PostScript and ASCII formats as well as an HTML version that is accessible from the PADE Help menu. These documents are located in the pade_doc subdirectory.

4. PADE Examples -- A set of sample files to aid the user in following the manager/worker example described in the PADE User's Guide. Two forms of a PADE setup script ( pade_setenv for csh and tcsh, and pade_export for sh, ksh and bash) to help the user set environment variables and the executables path are also included. These files are found in the examples subdirectory.
