[OMPI users] Unable to open a shared object libsmartio-rdmav17.so

I'm afraid the error message you're getting is from libibverbs; it's trying to load a plugin named libsmartio-rdmav17.so. That's not part of Open MPI, sorry.

That likely means that some dependency of libsmartio-rdmav17.so wasn't found, and the run-time loading of the plugin failed (vs. not being able to find the libsmartio-rdmav17.so file).

You might want to track down where you got the libsmartio-rdmav17.so file from.

Hello all,
This may be a silly question but I hope that someone does know the answer.
We use Open MPI to run the Intel Benchmarks to test InfiniBand and RoCE network fabrics. We recently installed OFED-4.17 and when we attempt to run the tests, we see the error below.

The folks who build OFED believe libsmartio-rdmav17.so is not part of the OFED package. It is not in RDMA-Core. I have searched for information on this object and can’t seem to find anything. If anyone knows anything about it or (especially) thinks that we should change our mpirun command options, or has pointers to where I should direct this question, I would appreciate the help.
OS: CentOS 7.4;
(kernel: 4.17.14-1.el7.elrepo.x86_64)
OFED: OFED-4.17-20180822-1352 (https://www.openfabrics.org/downloads/OFED/ofed-4.17-daily/OFED-4.17-20180822-1352.tgz)
I will be happy to provide any additional information if needed.
Thanks.
