Sorry for the delay in replying. By "aggressively", we mean that OMPI continually checks for process. I.e., it's basically a busy loop checking network devices (etc.) to see if anything has happened. Hence, the CPU will likely run at 100%. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
