NAME

       tkill - Terminate LAM on one node.

SYNTAX

       tkill [-dhvN] [-f <killfile>]

OPTIONS

       -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.

DESCRIPTION

       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).

FILES

       /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
