If you're using an ethernet, non-OS-bypass transport (e.g., TCP), you might also want to look at ethtool. Note that these counts will include control messages sent by Open MPI, too -- not just raw MPI traffic. They also will not include any traffic sent across shared memory (or other transports). -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
