Actually, we had a problem in our implementation that caused the system to
continually reuse the same machine allocations for each "spawn" request. In
other words, we always started with the top of the machine_list whenever
your program called comm_spawn. This appears to have been the source of th

fault-tolerance approach, the parents or other child processes should
not be affected by the death/failure of another child process. Right now
in Open MPI, if one of the child processes (which you spawned using
MPI_Comm_spawn) fails, th
