Hello,
I'm using openmpi-1.3a1r18241 on a 2 node configuration and having troubles
with the ompi-restart. I can successfully ompi-checkpoint and ompi-restart a 1
way mpi code.
When I try a 2 way job running across 2 nodes, I get
bash-2.05b$ ompi-restart -verbose ompi_global_snapshot_926.ckpt

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,

I'm finding that using ompi-checkpoint on an application which is very cpu bound takes a very very long time. For example, trying to checkpoint a 4 or 8 way Pallas MPI Benchmark application can take more than an hour. The problem is not where I'm dumping checkpoints (I've tried local and an nfs mou

thanks for your help!

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. :(

Does Open MPI v 4.1.0 or v 4.1.1 support using IP interfaces that have more
than one IP address?
