Getting started

Welcome to IGE!

Here you can find useful information about how we conduct scientific analysis, and ressources to get you up to speed with your fellow colleagues.

• We generally use GNU/Linux and MacOS distributions, so a prerequisiste is to know basic Unix Shell commands. If it is not your case, have a look at this tutorial.

• If you use a mainstream GNU/Linux distribution such as Ubuntu or Fedora, you can install most of the basic scientific software you may need (such as the NetCDF libraries) via the system’s package manager (apt-get, dns, etc.). If you are on MacOS, brew is a good way to manage this task.

• A quick way to back-up and access your work (scripts, notebooks, text files, etc.) from anywhere is to create a github account and to synchronize your work there. Learn how to do it here.

• If you work with Python, we recommend that you use mamba (a seamless/drop-in replacement for conda) to manage your librairies via environments. Learn how to do it here.

• Some like to use jupyter notebooks to have code and corresponding plots in the same document, along with some text, equations and/or pictures. Learn how to install and use them here

• You may want to access some remote computers in order to have more ressources than on your personnal laptop, or to access specific datasets. For this you have several options:

  • The lab servers ige-calcX allow you to access some CPUs and GPUs. Learn how to access and use them here.

  • The Grenoble meso computing center GRICAD for bigger computations. Learn how to use this resource here.

  • The national supercomputers located at IDRIS, CINES or CEA for even bigger computations [tutorials to come soon].

A list of commonly-used software and links to useful resources is available here.
