NAME
pvm - PVM version 3 console
SYNOPSIS
pvm [ -options ] [ hostfile ]
DESCRIPTION
Pvm is a stand alone PVM task which allows the user to interactively query and modify the virtual machine. The console can be started and stopped multiple times on any of the hosts in the virtual machine without affecting PVM or any applications that may be running.
When started pvm determines if PVM is already running and if not automatically executes pvmd3 on this host, passing pvmd3 the command line options and host file. Thus PVM need not be running to start the console. Once started the console prints the prompt:
pvm>

pvm reads $HOME/.pvmrc before reading commands from the tty, so it can be used to customize the console environment, for example: alias ? help
alias j jobs
setenv PVM_EXPORT DISPLAY
# print my id
echo new pvm shell
id
Starts up pvmd3 on the local host or connects to running pvmd3.
pvm hostfile
Starts up console and pvmd3, which in turn reads the host file and adds the listed computers to the virtual machine.
