For Gaussian it's necessary to adjust Linda_rsh to call a plain rsh instead of /usr/bin/rsh, so that the rsh-wrapper will catch it and route it to SGE's qrsh (in case you use Linda). | | -- Reuti Thank you! And these edits in /etc/ssh/sshd_config go on all the compute nodes, right? If yes, I could edit the extend-compute.xml and have them in place for next re-install.
