AFAIK is always a random one used - being it `ssh`, `rsh` or -builtin-. It's started per `qrsh -inherit ...` to listen only on this one. But MPI needs random ports being open too. At least for Open MPI you can limit it to a range of ports. -- Reuti _______________________________________________ users mailing list [email protected] https://gridengine.org/mailman/listinfo/users
