Using Adastra

This page provides a summary of examples and tools designed to help you get used with the Adastra environment.

Warning

Access to Adastra is for now (at least until 01/05/2023) only for computations on the GPU (MI200) partition!

Nevertheless it is also a way to have access to "old" files that we stored at CINES when using Occigen in the frame of the "Atmosphères Planétaires" GENCI project.

A couple of pointers

• Connecting to Adastra: We have retained group and login credentials from our previous setup on Occigen ; To connect to Adastra you need first go through the LMD gateway (hakim) or the IPSL (Ciclad/Spirit) gateway and then

ssh your_cines_login@adastra.cines.fr

And then you will probably want to switch project using the myproject command, e.g. to switch to "lmd1167" (the old "Atmosphères Planétaires" GENCI project)

myproject -a lmd1167

and to switch to "cin0391" (the 2023-2024 "Atmosphères Planétaires" GENCI project)

myproject -a cin0391

WARNING: when you switch projects, you also switch HOME directory etc.

To get all the info about dedicated environment variables (e.g. paths to SCRATCH, STORE, etc.) you can use

myproject -c
