CVL desktop FAQs
This page contains some of the most frequently asked CVL related questions. Technical user guides for using MASSIVE and CVL@MASSIVE can be found on the HPC documentation site.
Accessing the CVL Desktop
Accounts:
Getting started on the CVL Desktop includes step by step instructions for getting an account to use the CVL, installing the required software and connecting to a desktop.
Software required:
If you intend to use the Strudel Desktop application (a cross-platform application that is used to access interactive desktop sessions on the high-performance computing systems) instead of Strudel Web, you will need to install TurboVNC (a client/server software package that allows remote network access to graphical desktops).
No additional software is required if you use Strudel Web.

Accounts and passwords on MASSIVE
Why is my password not working?
Are you using the right password? Note that your CVL@MASSIVE password is NOT the same as your organisational login password, it is specific to the HPC systems
Have you tried resetting your password?
If you get stuck, email the MASSIVE helpdesk for assistance
Security
SSH: What is an SSH key and should I use it?
SSH, or secure shell, is the encrypted protocol used to connect to the CVL. SSH "keys" are authentication tokens that are created on your computer and are used to identify that computer to the system on subsequent logins
The Strudel desktop application that connects you to a CVL desktop has an option called "Remember me on this computer" that sets an SSH key on your computer. The Remember me ... option is not recommended if you share your computer with other users

Using the CVL desktop
Resizing the desktop
You can change the desktop size by entering a value in the "xrandr" command from a terminal on the desktop (e.g. xrandr -s "1920x1080"). If that does not work check the options in TurboVNC (CTL-ALT-SHIFT-o). Newer versions have a "Remote desktop size" under "Connection Options", set this to "Server" or the size you would like.
Forgotten passphrase (not to be confused with password - the passphrase is only used with the Remember me on this computer option, using Strudel)
You can recreate your passphrase key by deleting the old one; this will prompt you to create a new passphrase when you first log in with your MASSIVE ID. To delete the key: Identity > Delete Key, from the Strudel menu. You can also avoid the key by using Identity > Don't Remember Me.

Using Strudel on HPC and cloud sites:
You can use the Strudel Desktop application on HPC and cloud sites using a simple configuration file. Email the MASSIVE helpdesk for more information.
Strudel Web
Why can't I copy and paste?
In order to copy and paste from your machine to the remote desktop, you will have to use the Strudel Web clipboard tool. Instructions for using this tool are located on the Connecting using Strudel Web page.
Performance issues
If you have a slow connection, try the following to improve performance: from the options menu (CTL-ALT-SHIFT-o) you can set the connection speed Encoding method to one of the WAN options. This will reduce the quality of the rendering, but increase Texti Editspeed.
