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 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>

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
     id
 

EXAMPLES

       pvm

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.
