Access to ExCL

To become authorized to access ExCL facilities, please apply at https://www.excl.ornl.gov/accessing-excl/. You have the option of using your ORNL (ucams) account if you have one, or creating an xcams (external user) account if you wish.

Once you have access you have a couple of options.

• login.excl.ornl.gov runs an sshd service.

• There is a limited number of ThinLinc licenses available. Thinlinc (Xfce Desktop) can be accessed at https://login.excl.ornl.gov:300 for HTML5 services, and ThinLinc clients can use login.excl.ornl.gov as their destination. ThinLinc clients can be downloaded without cost from https://www.cendio.com/thinlinc/download. ThinLinc provides much better performance than tunneling X over ssh. A common stratagy is to access login.excl.ornl.gov via ThinLinc and then use X11 forwarding to access GUIs running on other nodes.
