The Environment

The Environment

The systems at HPC2N predominantly run various versions of Linux. If you have no experience with that, there are several good online sources that can be used to familiarize yourself with the basic commands. 

Email

Email

Together with an account at HPC2N you will also get an email address. However, you cannot log in to read it at HPC2N so it will need to be forwarded to your home/other email. This email address will be pulled from SUPR by HPC2N, and will be used by HPC2N to determine where to send you any information.

Thus you must make sure to keep the email address given in SUPR updated and valid. You can change it from this page: SUPR personal information.

Shells

In order to enable this, you must login with

SSH supports tunneling of X11 (X-Windows). This is also very useful if you want to open graphical displays from the remote machine on your local computer. To achieve this, an X11 server must be running on your local machine. The X11 connections are then tunneled and automatically encrypted by your SSH client.

For some types of graphical software this does not work correctly (if they need input from keystrokes). In those cases you must use
