The application side of grow / shrink is fairly immature -- we stopped
developing it quite a while ago (because of limitations in LAM and
because we're doing better/more interesting things in Open MPI :-) --
although they're not ready yet :-\ ). It's not really integrated well
into the MPI framework -- you'd have to dip down into the LAM run-time
to be able to intercept this and handle it properly. And even then,
it's not clear that LAM's MPI layer would be able to handle the death
of a process properly.
What are you trying to do?
