bpstat

bpstat displays a text-only snapshot of the current cluster state/configuration.

[root@cluster ~] #  bpstat
Node(s)	Status	Mode		User	Group
16-31	down	----------	root	root
0-15	up	---x--x--x	root	root

Using the -p option, you can view the PID for each user process running on the nodes. You can then pipe the ps command into grep to get the command string associated with it, such as ps -aux |grep 8370. Normal process signaling will work with these PIDs, such as kill -9 8369.

PID	Node	Ghost
8367	0	-1
8368	1	-1
8369	2	-1
8370	3	-1

See the Reference Guide for more details on the command options.
