You can add entries in /etc/hosts for the new IP interfaces if you like, but Open MPI won't care. Open MPI deals with IP addresses, and it'll auto-discover them (by looking at all the IP interfaces exported by the kernel) and use them as it finds them. -- Jeff Squyres jsquy...@cisco.com _______________________________________________ users mailing list users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/users
