lsrun is the only existing internal communication channel that could be used for this.
If you disable lsrun, then an alternative would be to use ssh with the lsf-pam module to selectively allow a user to login to a node where they had work running to kill the process.
Implementing an additional communication channel to kill a specific process could not be done as a patch.
To reply IBM_Systems_Developer:
Many administrators choose to disable lsrun to avoid users from running high load jobs, bypassing LSF queues.
Is there any reason why the user cannot either ssh to the node and kill the process, or use lsrun?
$lsrun -m gnbsx50588 kill 21851
That's a sweet requirement. It's what I call a gold nugget. I could see something along the lines of a PS line for the job too. That line would be captured at the running of bjobs and would provide all the processes in the control group, you could then use a command like:
bpkill jobid [-m hostname] pid1 ...
Very nice requirement indeed! Thanks!!!
