Both BLCR and Open MPI work just fine. Independently.
Checkpointing and restarting a parallel application is not as simple as
mixing 2 tools together (especially when we talk about a communication
library, aka. MPI), they have to cooperate in order to achieve the desired
goal of being able to cont
I don’t believe checkpoint/restart is supported in OMPI past the 1.6 series.
There was some attempt to restore it, but that person graduated prior to fully
completing the work.

Upon cr_restart I see the openlava_wrapper process, the mpirun process
reappearing but no orted and no lmp_mpi processes. Not obvious error anywhere.
Using the --save-all feature from
hmm, I'm not correct. cr_restart starts with no errors, launches some of the
