It has been clearly stated that the official position pushed forward by a majority of the Open MPI developer community is that fault tolerance is not needed so we (read this as the official version of Open MPI) do not support it.

However, a group of researchers have been working toward a version of Open MPI that supports the last fault tolerance proposal submitted for consideration to the MPI Forum. You can access it at

Hi all,

Can anyone explain me the fault tolerant features in OpenMPI? I've read the FAQs and some papers about this topic listed in, but still can't figure out when one node of my supercomputer system fails down during computing, what would happen with the fault tolerant mechanism in OpenMPI, and what should we system administrator do after the failure (or before). 

Can anyone help me? My boss want me to deploy OpenMPI in our system cuz he want the fault tolerant feature.

Thanks very much.
