TKILL(1) LAM TOOLS TKILL(1)
tkill - Terminate LAM on one node.
tkill [-dhvN] [-f <killfile>]
-d Turn on debugging mode. This implies -v.
-h Print the command help menu.
-v Be verbose.
-N Pretend; do not take action.
-f <killfile> Use <killfile> as the name of the kill file.
The tkill tool terminates the LAM session started by hboot(1) on the
local node. tkill makes use of a kill file created by the LAM kernel,
which contains the process identifiers of every LAM process in ASCII
format. A SIGHUP (see signal(3)) signal is sent to every process
listed in the kill file. tkill waits a short period of time for each
process to die. By adding the debug option, the user can see the final
disposition of each process. The mission is accomplished if all pro-
cesses end up dead.
In LAM, the first process to be killed is always the kernel. When the
kernel receives its termination signal, it propagates the signal to all
of its constituent processes. Therefore, tkill will ordinarily be rac-
ing the kernel to kill all other processes. This redundant aspect of
tkill allows it to be used as a general purpose tool in association
/tmp/lam-$USER@<hostname> the kill file, created by the kernel,
where $USER is the userid, and <hostname>
is the name of the local machine
