Global models of the Earth system require the use of massive computational resources to handle big data. This means that the use of numerical calculation needs to be very efficient and managed by expert users, in order to minimise the resources that are only finalised to make software user friendly.
This is the reason why the majority of the web servers run over the Linux operating system, which is addressed to experienced users. But what is an operating system? It essentially is a system software that manages computer hardware and software resources, and provides common services for computer programs.
To meet a diversity of user needs, several operating systems have been developed. Windows is the most commonly used. We will focus on the above mentioned Linux system, that is openly available.
You can find introductory slides on Linux here. Also, you can find here an introductory guide to the system, and here an open source course, if you get passionate and motivated to learn more. Of course, the web provides several additional references.
Also, please refer to the videos of the lectures for additional information.
