prkill - Kill applications on a parallel machine

SYNOPSIS

prkill [option] application

DESCRIPTION

This command starts a number of remote shells to kill applications whose name matches application (match in the sense of grep(1)). prkill uses rsh(1) for kill invocation. rsh only works if the caller processor is trusted by the callee processor. Therefore, the caller processor must be present in the user's .rhost file.
The hosts to be visited are specified with the -p or -e option; by default the file .prunpool in the user's home directory is taken if it exists; otherwise the prun(1) default pool is taken.

OPTIONS

-e list
hosts from list, a (possibly quoted) text string that contains the host names. An abbreviation mechanism is supported: if a hostname ends in a number, a range of hosts starting at that hostname and numbering upwards is specified by appending ":<n>" to the hostname, where <n> is the range size.
-p pool
host list on file pool (default: $HOME/.prunpool, or prun default, see below).
-n
echo rsh kill commands, do not execute.
-reserve id
kill the prun run with id id. This is only allowed if the owner of id id has invoked prun(1) with the flag -kill-me-plenty.
-override
used in conjunction with -reserve. Kills the indicated reservation even if the owner of the prun reservation id has not set the flag -kill-me-plenty.
-v
be more verbose.
-x list
skip hosts on list, a (possibly quoted) text string that contains the host names. An abbreviation mechanism is supported: if a hostname ends in a number, a range of hosts starting at that hostname and numbering upwards is specified by appending ":<n>" to the hostname, where <n> is the range size.
-signal
Send signal signal, in the manner of kill(1).
-?
print usage.
