Issues You May Encounter When Using MobileVisLab

• Ensure that in all the firewall policies (public, private) the exception is added for TurboVNC.

• The size of the MobileVisLab session could be too big on your laptop. Adjust the height and width in this file at your own home folder: $HOME/.vnc/stee-vnc.settings.

• If you are NOT working within NUS Intranet, please login to http://webvpn.nus.edu.sg first before you login to NUS HPC portal and start MobileVisLab.

• The problem could come when your home directory disk quota is exceeded. Backup and remove files in your home directory to release the disk space.

• At any login session to the other HPC systems, issue command “bjobs” and check if there are any pending or failed vislogin jobs. If yes, Terminated them using “bkill JOBID” before you try again.

• Sometimes, you can try to close the restart TurboVNC Viewer if you suddenly cannot start MobileVisLab, or clear your browser history, close browser and re-open the browser and click on MobileVisLab again.
