There us no need to have SSH enabled for such a setup. a) Configure the /etc/ssh/sshd_config on all the nodes so that only admin staff can log in to a node. I created a group for this purpose "operator" for them and use "AllowGroups root operator" in the mentioned file. b) To ease the login to the nodes, one can define hostbased authentication: https://arc.liv.ac.uk/SGE/howto/hostbased-ssh.html (but this is optional). c) Be sure that the SGE startup of remote processes uses the "builtin" method: $ qconf -sconf #global: ... qlogin_command builtin qlogin_daemon builtin rlogin_command builtin rlogin_daemon builtin rsh_command builtin rsh_daemon builtin https://arc.liv.ac.uk/SGE/htmlman/htmlman5/remote_startup.html d) Compile Open MPI with the switch "--with-sge", while MPICH and Intel MPI (which is also related to MPICH) support this out of the box. -- Reuti _______________________________________________ users mailing list users@gridengine.org https://gridengine.org/mailman/listinfo/users
