Installing PVM

On the Cluster at the CIM, PVM is installed systemically in the directory: /usr/src/pvm3/
It is recommended to copy this directory recursively to your home directory:

/home/beowulf/scottyb> cp -Rfv /usr/share/pvm3 ~/pvm

[Please don't overwrite an important directory called ~/pvm if you already have one!!]
If you use Bash add the following line to your ~/.bash_profile:

###################################################################
# This is the snippit that everyone should include in their rc file
# It looks for a local pvm directory which should be a copy of the
# system one, or it uses the system on in /usr/share/pvm3

export PVM_ROOT=$HOME/pvm

if [ -f /usr/share/pvm3/lib/bashrc.stub ]; then
        source /usr/share/pvm3/lib/bashrc.stub
fi
###################################################################

or the C-shell version for your ~/.cshrc:

###################################################################
# This is the snippit that everyone should include in their rc file
# It looks for a local pvm directory which should be a copy of the
# system one, or it uses the system on in /usr/share/pvm3

setenv PVM_ROOT ~/pvm

if (-f /usr/share/pvm3/lib/cshrc.stub ) then
	source /usr/share/pvm3/lib/cshrc.stub
endif
###################################################################

NB: Don't set the PVM_ROOT environment variable if you haven't done the copy, ie. if you don't have a directory called ~/pvm. Just leave that line out and things will still work.
Create a file in your home directory called ~/.pvmrc and copy the following line into it:

add miles.beowulf.cim trane.beowulf.cim bird.beowulf.cim louis.beowulf.cim ella.beowulf.cim brownie.beowulf.cim monk.beowulf.cim dexter.beowulf.cim henderson.beowulf.cim jarrett.beowulf.cim corea.beowulf.cim mobley.beowulf.cim morgan.beowulf.cim rollins.beowulf.cim tyner.beowulf.cim

Starting PVM

Start PVM by issuing the command:

/home/beowulf/scottyb> pvm

You should see very much like:

[scottyb@gil ~]$ pvm
add miles.beowulf.cim trane.beowulf.cim bird.beowulf.cim louis.beowulf.cim ella.beowulf.cim brownie.beowulf.cim monk.beowulf.cim dexter.beowulf.cim henderson.beowulf.cim jarrett.beowulf.cim corea.beowulf.cim mobley.beowulf.cim morgan.beowulf.cim rollins.beowulf.cim tyner.beowulf.cim

pvm> quit

Typing "quit" at the PVM command line will leave pvm in a running state, and ready to go.
Typing "halt" will end your PVM session, this should be done at the end of each session, but doesn't really matter.
