ah. okay doesn't surprise me but bummer.

yep lsf is one of the tools i've been pointed to by our developers.  does
it support transparent checkpointing and migration, that was one of the
features of condor i really liked (though the requirement of relinking the
apps makes it unfeasible).

any comments on how it compares with other tools?

yep that's exactly the problem we have is at the end of a project when we
have to do gate level simulations.
