For my best knowledge rate=2 in partition config file will be related to corresponded IPoIB multicast group for this partition, and not to PathRecord. In PathRecord you get maximum available rate on the requested path. > Have I done anything wrong? is it a known issue? what does it means > when the SM prints "min rate = 6" Here "min rate" means minimal common rate on the path.
