PVM(1PVM)                       PVM Version 3.4                      PVM(1PVM)




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 with-
       out affecting PVM or any applications that may be running.

       When started pvm determines if PVM is already running and if not  auto-
       matically  executes  pvmd3 on this host, passing pvmd3 the command line
       options and host file.  Thus PVM need not be running to start the  con-
       sole.  Once started the console prints the prompt:
            pvm>

       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

           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

                    -(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
           id


EXAMPLES

            pvm
       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.
