Yes, we have several mechanisms other than rsh/ssh available for
starting a LAM/MPI universe, but I'm afraid that we do not have one for
LoadLeveler. :-(

That being said, we do export an API that could be used to allow LAM to
use LoadLeveler (the boot SSI -- see its docs at
http://www.lam-mpi.org/using/docs/). All that would be required would
be to write a boot SSI module that calls the relevant LoadLeveler API
calls and you should get native job startup / shutdown. We
unfortunately do not have the resources (i.e., people) to do this -- do
you? We'd be happy to provide any assistance / technical discussions
to help.
