Subject: Re: [OMPI users] Checkpointing automatically at regular intervals
From: Josh Hursey (jjhursey_at_[hidden])

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.
