Xming
Xming allows Windows machines to display a graphical Linux program which is running on a remote Linux server. You can download Xming here.
To enable Xming in the PuTTY configuration, navigate to "Connection > SSH > X11" (left side panel), and check the box "Enable X11 forwarding". If you save this configuration to your session, you only need to do this once.
If Xming is active, you will see its' symbol in your taskbar.
WinSCP
WinSCP allows transferring files from your local system (e.g., laptop) to the cluster or vice-versa. You can download it here.
When you open WinSCP you need to connect to a "New site". You will need to fill in the "Host name", "User name", and "Password". Jureca host name is jureca.fz-juelich.de. Juwels host name is juwels.fz-juelich.de.
When you press "Login", you will be prompted to type in your passphrase for the SSH key that you created previously.
After that, you will see two panels. To the left is your local system and to the right the JSC system. Simply drag a file or folder to transfer it from one system to the other.
