Hi Reuti, Thank you for the reply. The X11 forwarding is "yes" in the sshd_config on both the master and the compute nodes. Can the rlogin_command and rlogin_daemon used of submitting batch jobs using qsub? I'm now setting up the rlogin_command and rlogin_daemon, will update once it is done. Thanks,Bharani

It > works fine. most likely you need X11 forwarding and setup SGE's remote startup mechanism to use it for rlogin_command and rlogin_daemonat least: http://arc.liv.ac.uk/SGE/howto/qrsh_qlogin_ssh.html and add "-X -Y" as options. For a Tight Integration of an SSH startup mechanism it might be necessary to adjust PAM in addition, but this we can check later. -- Reuti
