Alberto, In the master there is no such support (we had support for migration a while back, but we have stripped it out). However, at UTK we developed a fork of Open MPI, called ULFM, which provides fault management capabilities. This fork provides support to detect failures, and support for handling the fault in the MPI layer.
I suggest you look at fault-tolerance.org for more info. George.
