The warning is telling you that we don't see libnuma on that machine, and therefore we cannot bind memory to your local process. You can turn the warning off by adding
-mca hwloc_base_mem_bind_failure_action silent As for why you get different outputs, I honestly don't know - I can't replicate that behavior (and I've now tried on multiple installations), which makes me suspicious that it has something to do with your setup. One thing you could check is that your path and ld_library_path on linpc1 is pointing to the right version of OMPI when remotely invoked - i.e., that the orted being started on linpc1 when you execute mpirun on tyr is in fact the orted from the desired version of OMPI. It looks to me like maybe that isn't correct.
