Summary and Schedule

This lesson introduces environmental sustainability principles in the context of high performance computing systems.

We use the UK National Supercomputing Service, ARCHER2 as an example throughout this lesson but the principles and learning should be applicable to any HPC system.

Prerequisites

• You should have basic familiarity with using a command shell, and the lesson text will at times request that you “open a shell window”, with an assumption that you know what this means.
  • Under Linux or macOS it is assumed that you will access a bash shell (usually the default), using your Terminal application.
  • Under Windows, Powershell and Git Bash should allow you to use the Unix instructions. We will also try to give command variants for Windows cmd.exe.
• The lessons will sometimes request that you use a text editor to create or edit files in particular directories. It is assumed that you either have an editor that you know how to use that runs within the working directory of your shell window (e.g. nano), or that if you use a graphical editor, that you can use it to read and write files into the working directory of your shell.

Target audience

This lesson is aimed at researchers and research software engineers (RSEs) who use HPC systems. No knowledge of environmental sustainability principles is assumed.
