Installing and Testing HeNCE

This section describes how to install and test HeNCE. We assume that you will have obtained HeNCE pre-compiled. Instructions for compiling it from source can be found at the end of this document.

1. PVM must be compiled and installed before HeNCE. Detailed instructions come with PVM, but the process is quite simple. Unpack the source file in your UNIX home directory. Software will be placed into directory pvm3. CD to directory pvm3 and enter ``make'' to build and install PVM. HeNCE requires that PVM be installed within directory pvm3 within your home directory. Do this first!

   If you are using PVM 3.3 or later you muat ensure that environment variable PVM_ROOTis set to ``/pvm3'' automatically whenever you login. For example, csh users will need to add

   
   setenv PVM_ROOT ~/pvm3

   to their .cshrc file.

2. HeNCE pre-compiled distribution files should be unpacked in your UNIX home directory. Software will be written into directory pvm3.

3. Be sure that ``/pvm3/bin/ARCH'' is in your UNIX path for each machine that will be used with HeNCE in any way. ``ARCH'' is an architecture name.

4. Ensure that you can login without entering a password to all of the machines that will be a part of your virtual parallel machine from the machine on which you will run htool. See the ``Default HeNCE Environment'' above.

If you are confused about how to unpack HeNCE or PVM files, you should probably seek the advice of a local UNIX guru, but here are some hints. Suppose the file you wish to unpack is called NAME.tar.Z.uu where ``NAME'' is some prefix. First enter ``uudecode NAME.tar.Z.uu'' to create file NAME.tar.Z. Then, enter

zcat NAME.tar.Z | tar xf -

to unpack the file.
