This is correct -- LAM will maintain a file of all the PIDs of processes
running the LAM RTE on that node in the session directory on that node.
However, I would consider this file "internal", and therefore
intentionally undocumented -- meaning that we're allowed to change it at
any time. I don't know at this point if we ever will, but it is possible.
I'd therefore against using it, and instead recommend using the boot SSI
module / job scheduler RTE daemon method.
Just my $0.02. :-)
