Currently, there is no mechanism to checkpoint every X minutes in Open
MPI.
As mentioned below you can use a script to initiate the checkpoint
every X minutes. Alternatively it should not be too difficult to add
such a feature to Open MPI. If enough people would be interested I can
file a feature bug to add such a feature in a future release.

Hi,
I think that you can write a simple script such as:
wihle `pgrep mpirun` != ""
ompi-checkpoint `pidof mpirun`
sleep 5
done

Dear All,
I can manually checkpoint an MPI application using OPEN MPI
and BLCR. However, I now want to checkpointing my application
automatically at every 5 minutes. Is there a way in OPEN MPI to
ensure automatic checkpointing without the user intervention while
the application is running?
Thank you
Regards,
Kritiraj
