some kind of distributed programs can survive the loss of one or more
processes,  also there have been fault-tolerant MPI implementations
(like FT-MPI)  that would allow a program to survive the loss of one
or more rank(s) if it were designed to.  The OpenMPI folks have been
talking about adding in some of the fault-tolerant features
