Hello,
I think that there is a problem with the ompi-restart   from the release r-21197.
in fact ompi-restart can restart only if the checkpoint directory is  $HOME.
For example the checkpoint folder is $HOME.
if i try ompi-restart -i  $HOME/ompi_global_snapshot_7056.ckpt/  it doesn't work and i get

msbouguerra@sol-5:~$ ompi-restart -i $HOME/ompi_global_snapshot_7056.ckpt/
--------------------------------------------------------------------------
Error: The filename (/home/grenoble/msbouguerra/ompi_global_snapshot_7056.ckpt/) is invalid because either you have not provided a filename
       or provided an invalid filename.
       Please see --help for usage.

--------------------------------------------------------------------------



and when i try :   ompi-restart -i ompi_global_snapshot_7056.ckpt/    it works  and i get


msbouguerra@sol-5:~$ ompi-restart -i ompi_global_snapshot_7056.ckpt/

msbouguerra@sol-5:~$


So when i use another folder as checkpoint directory the restart failed
