> I can get around this by adding the "--mca btl_openib_cpc_include rdmacm" option.  However, I have another host with a different HCA with all the same drivers and software versions that I can run this same command successfully with using the rdmacm option.  What could be causing one of my environments to fail but the other to work fine (without the rdmacm option)?
