There's been lots of turnover on the project recently so the previous experts for checkpoint/restart in MPICH are gone, but from what I can tell, it appears that it might currently be broken. This ticket (https://trac.mpich.org/projects/mpich/ticket/1144) is the only documentation about the subject that I can find, but I think the assumption is that everything has bit rotted and will need to be updated before it works again.
