Not quite. The openib BTL does use the modex to send around connection information. The actual connections are made lazily -- just like the TCP BTL -- but the OOB CPC (i.e., the default connection mode in the openib BTL) uses RML to do the 2/3 way handshake. That's all. But the point here is: the openib BTL does rely on the modex. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
