DPVM(1DPVM) — Commands
NAME
DPVM − Digital PVM Console
SYNOPSIS
DPVM [hostfile]
DESCRIPTION
dpvm is a standalone Digital PVM task which allows the user to interact with the virtual machine. The console can be started or stopped independently of any other Digital PVM applications running on the "virtual machine". A "virtual machine" is a set of host systems where PVM applications can run.
When started, dpvm either launches a new daemon on the current host or connects to an already running daemon.
The user queries or modifies the virtual machine by issuing console commands.
The following commands are available:
add hostname(s)− adds host(s) to virtual machine
alias− defines or lists command aliases
conf− lists virtual machine configuration
delete hostname(s)− deletes host(s) from virtual machine
echo− echoes arguments
halt− terminates Digital PVM processes including console
help command− prints information about a command
id− prints console task id
jobs− lists jobs running
kill− terminates task
mstat− shows status of specified hosts
ps −a− lists processes currently on virtual machine
pstat− shows status of single Digital PVM task
quit− exits console leaving daemon and Digital
PVM tasks running
reset− kills all Digital PVM processes except consoles
setenv− displays or sets environment variables
sig signum task− sends signal to task
spawn [opt]− starts a Digital PVM application
opts are:count− number of tasks, default is 1

?− enables debugging
>− redirects task output to console
>file− redirects task output to file
>>file− redirects task output append to file

The Hostfile is made up of a listing of machine names, one per line, that Digital PVM will use as the virtual machine.
