One possible reason this could be happening is that the openib BTL is excluding itself if you use MPI_THREAD_MULTIPLE. The openib BTL is the entity that is responsible for the fork warning -- if it's not being used, then no warning is issued because there is no problem with forking. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
