Decision tree on how to log in to Bianca
Question A, 'Can you get inside the university networks?' is commonly answered 'yes' for anyone with an email address at a university in Sweden. The UPPMAX documentation on how to get inside the university networks should allow anyone to do so.
Question B, 'Need/prefer a remote desktop?' is about if you prefer a visual/graphical environment to work with Bianca, which will be similar to what most of us are used to. A 'yes' is more suitable for new users, although it is considered a more clunky (it responds slower on user input) and clumsy (copy-pasting to it needs multiple mouse clicks) way to work. A 'no' is more suitable for users comfortable with a terminal and works smoothly.
How does the Bianca remote desktop look like?
One can pick multiple remote desktop environments, such as GNOME and XFCE (and KDE, don't pick KDE!).
The Bianca XFCE remote desktop environment
A more populated Bianca XFCE remote desktop
- A remote desktop environment, also called 'graphical environment', 'GUI environment', 'ThinLinc environment'
How does the Bianca console environment look like?
The Bianca console environment
- A console environment, also called 'terminal environment' or 'terminal'
Question C, 'How to log in?' is about how you prefer to login. The option 'Using a password' is more suitable for new users, as it is easy to setup and understand. However, one does need to type his/her password every time one logs in. 'Using SSH keys' is harder to setup, yet more convenient.
Will a local ThinLinc client work too?
No.
One really can only access the Bianca remote desktop environment via the website.
Here are the ways to log in to Bianca:
- 1.Use the Bianca remote desktop website
- 2.Use a terminal and password to access Bianca directly
- 3.Use a terminal and SSH keys to access Bianca directly
- (not recommended) 4.Use the Rackham remote desktop website to log in to Bianca's remote desktop environment
- (not recommended) 5.Use a terminal and password via Rackham to log in to Bianca's console environment
- (not recommended) 6.Use a terminal and SSH keys via Rackham to log in to Bianca's console environment
After login, you will be on a login node.
How to behave on a login node
On a login node, one can and should do simple things only: it is a resource shared with all other users on that node.
If you need to do more intense calculations, use the Slurm job scheduler.
If you need to do more intense calculations interactively, use an interactive node.
