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