  • 1.  LSF interactive job submission - xterm

    Posted Thu July 27, 2023 02:02 AM

    Hello,

    We're having a LSF HPC cluster on CentOS 7.6 running.
    When I login to a login server I can open an xterm with command 'xterm' and with a bsub command using LSF.
    When I ssh to another login server, my display variable will be forwarded thanks to a ssh setting. (xforwarding=yes in sshd.conf).
    I still can use the command 'xterm' to open an xterm windows on the other login server.
    When I now want to submit an xterm to a queue with bsub, xterm will not be displayed because of it's $DISPLAY variable. It says:
    xterm Xt error: Can't open display: <hostname>:12.0

    It seems that bsub will not use the Xforwarding origin from ssh.

    I'm out of ideas and maybe can help me with this issue.

    Thanks in advance.

    Not sure if you use -IX bsub option?
