Graphical Login Access to the SHPC Condos

IMPORTANT NOTICE: This service has been decommissioned for now. Please contact cades-help@ornl.gov for any questions.

The Graphical Login Service provides fast and secure access to a Linux desktop environment within the CADES SHPC Condos. This service is recommended for users that need to run visualization tools or other graphical applications on the cluster without installing an X11 server on their local desktop. This service also works better at displaying OpenGL applications than traditional X11 forwarding. Users that only require terminal (text based) access to the cluster are advised to connect with ssh instead.
