Hi Jeff,
Assuming you did **not** explicitly configure Open MPI with
--disable-dlopen, you can try
mpirun --mca pml ob1 --mca btl vader,self ...
Cheers,
Gilles

I am running on a single node and do not need any network support. I am
using the NVIDIA build of Open-MPI 3.1.5. How do I tell it to never use
anything related to IB? It seems that ^openib is not enough.
Thanks,
Jeff
