pvm − PVM version 3 console
pvm [ −options ] [ hostfile ]
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:
|
