No. > If I include RDMA CM to connect my nodes, isn't that sufficient? It's been quite a while, but IIRC, RDMA CM requires IPoIB. FWIW: Open MPI actually defaults to using TCP for wiring up IB connections (doesn't have to be TCP over IPoIB -- it can be regular old TCP over Ethernet). -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
