Does Open MPI v 4.1.0 or v 4.1.1 support using IP interfaces that have more
than one IP address?
#x27;m using is based on the algorithm used by LAM/MPI, but
implemented at a higher level. There are a number of improvements
that
I can explore in the checkpoint/restart framework in Open MPI.
If this is critical for you I might be able to take a look at it, but
I can't say when. :(

Josh,
I'm responding to some outstanding questions about the env. I'm trying to
ompi-restart in.
My answers to your questions are sprinkled below, and include a few more
questions based on attempts I've made to get a multi-node restart working.
thanks,
