    I set up a cluster of 18 nodes using Open MPI and BLCR library, and the MPI
program runs well on the clusters,
but how to checkpoint the MPI program on this clusters?

what I have done is that: I run the program using mpirun in the shared
directory on the master node, and use
ompi-checkpoint command in another terminal on master node, it will create
an checkpoint file,but the MPI program
are not terminated as what happened in single machine. Also, the
ompi-restart also doesn't work on cluster.

what should I do ?

Cheers!
