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

• Changing the password of your CINES account

When your password is close to expiring, CINES asks you to change it on this website : https://rosetta.cines.fr

Please note that you can access this website only if you are on a machine that you declared as a gateway for Adastra. At LMD, we have generally declared hakim.lmd.jussieu.fr (aka ssh-out) and ciclad.ipsl.jussieu.fr as gateway machines. Hakim doesn't have any browser installed, but you can launch firefox on Ciclad and connect to the rosetta website. If that doesn't work, you will have to mail svp@cines.fr
