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. > On Aug 24, 2018, at 9:23 AM, Llolsten Kaonga <l...@soft-forge.com> wrote: > > 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.
