I created a feature ticket for this if you wanted to track it:
https://svn.open-mpi.org/trac/ompi/ticket/1961
I do not know when I will have time look at implementing this (of
course patches from the community are always welcome). But hopefully
in the next couple months.
Cheers,
Josh

Dear Josh,
I am sure it will definitely be good because if someone
is using OPEN MPI for checkpointing his application, he will not
want to sit and checkpoint the application manually; and this can be
a real pain if its a long running application.
I would imagine an automatic restart from the last checkpoint in
case of failure would also be interesting.
Many thanks.
Regards,
Kritiraj

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
