Hi Rene, that didn't fix the problem, unfortunately. I did manage to get it to fix it by calling addprocs from a remote machine in the cluster. So I think there is a problem with firewalls -- perhaps the remote machine is trying to SSH back into the local one and failing. It would be nice if these Julia library functions would emit more informative error messages or perhaps have a verbose mode.
