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 processes 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 racing the kernel to kill all other processes.
This redundant aspect of
tkill
allows it to be used as a general purpose tool in association with hboot(1).
