Installation of pLUCAS

The serial version of LUCAS, outlined in Appendix B, should be installed, as much of the same software is needed in both installations. Additionally, TCL 7.4 and Tk 4.0 or later must be installed to use the parallel GUI. They can be obtained via anonymous FTP at ftp://ftp.cs.berkeley.edu/ucb/tcl. Information about TCL/Tk, its use and installation can be found at URL http://www.sco.com/Technology/tcl/Tcl.html. The Parallel Virtual Machine (PVM) version 3.3.7 or later also needs to be installed on each host participating in the virtual machine. PVM can be downloaded from
ftp://ftp.netlib.org/pvm3 and http://www.epm.ornl.gov/pvm/
pvm_home.html has on-line information.

Once the software is installed:

1. Edit the first line of gui.tcl to point to the local installation of TCL. (e.g., #!/home/lucas/local/bin/wish)
2. Make sure the PVM_ROOT and PVM_ARCH environment variables are set in the user's $HOME/.cshrc file.
3. Make sure each host is in the user's .rhosts file.
4. Install PVM lib directory under pLUCAS.
5. Place pLUCAS analysis executables for each architecture in the appropriate PVM bin directory
6. Install the optional $HOME/.plucasrc file.
7. Run the pack script to create the export tar files.
8. Run the plucas_install script on the master node. This installs the master node in /var/tmp.
9. Run the plucas script to launch pLUCAS.

NOTE: It is assumed that the host running the GUI will be the master node. The $HOME/.plucasrc file is filled with X resources:
