You do need to catch the proccess id (pid) of the passed argument ($1) into a new variable, and 'kill that'..

tkill

TKILL(1)							     LAM TOOLS								  TKILL(1)

NAME

       tkill - Terminate LAM on one node.

SYNOPSIS

       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

       hboot(1), lam-helpfile(5)
