    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:

    The following console commands are available:

        add  hostname(s)    - Add hosts to virtual machine
        alias               - Define/list command aliases
        conf                - List virtual machine configuration
        delete  hostname(s) - Delete hosts from virtual machine
        echo                - Echo arguments
        export              - Add environment variables to spawn export list
        halt                - Stop pvmds
        help [command]      - Print helpful information about a command
        id                  - Print console task id
        jobs                - List running jobs
        kill  task-tid      - Terminate tasks
        mstat host-tid      - Show status of hosts
        ps -a               - List all PVM tasks
        pstat task-tid      - Show status of tasks
        quit                - Exit console
        reset               - Kill all tasks
        setenv              - Display/set environment variables
        sig  signum task    - Send signal to task
        spawn [opt] a.out   - Spawn task
             opts are: -(count)  number of tasks, default is 1
                       -(host)   spawn on host, default is any
                       -(ARCH)   spawn on hosts of ARCH
                       -?        enable debugging
                       ->        redirect task output to console
                       -> file   redirect task output to file
                       ->>file   redirect task output append to file
        trace               - Set/display trace event mask
        unexport - Remove environment variables from spawn export list
        unalias - Undefine command alias
        version - Show libpvm version

    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



    Starts up pvmd3 on the local host or connects to running pvmd3.

            pvm hostfile

    Starts up console and pvmd3, which inturn reads the host file and adds the listed computers to the virtual machine.
