This guide, which was largely inspired from Earth IPSL wiki page, provides good practices to reduce as much as possible the environmental footprints of simulations performed with our GCMs.

Which model is needed to answer my research question ?

Is a full-fledged climate model needed to answer my research question? Could a simple, less computationally-expensive model (such as OSCAR for present-day and future climate or iLOVECLIM for paleoclimates) provide me the answer?

Are there experiments that already exist to answer my research question?

Is my experimental design well thought through?

Notify the configuration manager

Can I share my results to help another researcher?

Consider the necessary diagnostics

Check everything before launching the production run

Two pairs of eyes are better than one

Don't wait for the end of the simulation before checking

Share your results with other researchers

Decrease the number of inodes
