I’m using lam to run a large number of parallel jobs on a cluster using the PBS batch system.  Each script that is submitted performs a lamboot command.  It is very likely that more than one job may be started on a single node.  I have been setting the LAM_MPI_SESSION_SUFFIX to a job ID number so that there is a unique LAM deamon associated with each batch job that is submitted.  My particular question is what happens when I execute the lamhalt command.  Since there is no option to specify the appropriate suffix for which lam deamon to close what happens.  Will lamhalt only halt the lam deamon that was used for that particular job.  If so, how does it know which one to kill.  I don’t want lamhalt to halt the deamon for a different job that happens to be running one the same node.
