Hi, I'm hoping someone can help me locate a SpMV benchmark that runs w/ Open
MPI so I can benchmark how my systems are interacting with the network as I add
nodes / cores to the pool of systems. I can find SpMV benchmarks for single
processor / OpenMP all over, but these networked ones are prov
Yeah we have ran into more issues, with rdmacm not being avialable on all of
our hosts. So it would be nice to know what we can do to test that a host
would support rdmacm,
Example:

No OpenFabrics connection schemes rep
Usually that means you have a mismatch in your OMPI versions - you may have
built the app with one version and are running it against another, for
example, or perhaps compiled them against MPICH and run them using OMPI's

support is known to be limited and the performance poor.
Thanks :)
I absolutely see why s
