Not at the moment.
This would be a neat addition to Open MPI if application developers
see a need for it. There are many issues surrounding this type of a
feature (like any feature). Most of them surround what an application
expects and requires from such an API. One such question is whether an
MPI_Checkpoint function would imply a coordinated global checkpoint
with barrier or a local uncoordinated checkpoint or something else.
The checkpoint/restart framework in Open MPI was designed to allow for
some exposure of the checkpoint/restart routines. So depending on what
you are looking for it may be fairly straight forward to expose a
simple checkpoint/restart API.
I have not heard many requests for such an API, but I may be willing
to help investigate if users are interested.
Cheers,
Josh

Are there plans to provide an API that would allow a fault tolerant
