The MPI standard does not provide explicit support for process
migration. However, some MPI implementations (including Open MPI) have
integrated such support based on checkpoint/restart functionality. For
more information about the checkpoint/restart process migration
functionality in Open MPI see

I can explain you the complete problem if you want.

I'm not sure what you me
I'm not sure what you mean by "migrate". Are you talking about restarting a
failed process at a different location? Or arbitrarily moving a process to
another location upon command?

You might want to contact Josh Hursey, the author of most of Open MPI's
checkpoint / restart / migration work; it would probably be best to ping him on
the devel list (vs. the general user's list).
