The Parallel Virtual Machine (PVM) allows computers which are connected over a network to be used as a single distributed parallel computer.
Installation of PVM is straightforward from packages, for configuration environment variables need to be set up:
add to /etc/profile: export PVM_ROOT=/usr/share/pvm3 export PVM_TMP=/tmp export PVM_RSH=/usr/bin/ssh export PVM_ARCH=LINUXX86_64 export PATH=/usr/local/bin/:$PATH
In the pvm environment (which you enter typing 'pvm') after adding your machines you can then try the following and see if you can get a list of your machines.
spawn -> -10 /bin/hostname
