You shouldn't have to do anything - LAM just does the "right" thing to
not leave PBS's session tracking. Your application can't leave the
session it was started in (by calling setsid() or something like that),
or PBS can't track usage. Note that OpenPBS is notorious for not
getting the small things like this correct - you might want to make
sure that PBS is tracking usage for simple applications (just have an
app that enters a tight spin loop to eat up cycles - no MPI).
Hope this helps,
Brian
