SSH policy changes on access machine

Dear users,

Due to multiple occurences of bad usages of the access machine, the technical team has decided to change the SSH connection mode to the infrastructure.

Starting from october 29th 2026, the infrastructure SSH server configuration won't allow anymore to connect to the access.grid5000.fr machine. Users will be required to either use a proxyjump in the ssh command line and connect directly to site's frontend or nodes:

$ ssh -J access.grid5000.fr nancy.grid5000.fr

$ scp -J access.grid5000.fr <file> nancy.grid5000.fr:

Or to use the long time already recommended proxycommand configuration in the user's workstation ssh configurations.

Host g5k

 User g5k_login
 Hostname access.grid5000.fr
 ForwardAgent no

Host *.g5k

 User g5k_login
 ProxyCommand ssh g5k -W "$(basename %h .g5k):%p"
 ForwardAgent no

This will have one major consequence : home folders won't be accessible anymore on access machine.

to transfer file from outside, you need to update your scp/rsync command :

outside:~$ rsync -avz local_file rennes.g5k:remote_dir/

to transfer between sites, you need to execute the transfer from a frontend :

g5k_login@flyon:~$ rsync -avz local_dir/ fgrenoble.grenoble:remote_dir/

Debian 13 "Trixie" std environment is now the default environment on (almost) all nodes

Dear users,

We are pleased to announce that Debian 13 (Trixie) std environment is

now the default environment on most nodes. See `kaenv3 -l debian%13%` for a list of available variants.

There is some significant evolutions, particularly regarding the

environment modules. Indeed, some components that were included in the environment images are now provided by modules loading, including CUDA, ROCm and OpenMPI.

Node network interface now have both IPv4 and (public) IPv6 addresses

by default, which should have no impact on most uses.

For more informations, see the Release Notes, available at

https://www.grid5000.fr/w/Debian_13_Trixie_environments_release_notes

As previous default environment move, frontend of every sites have been reinstalled in Debian 13 too.

If you have any questions or problems, please contact <support-staff@lists.grid5000.fr>

Some clusters under Debian 13 "Trixie" environment by default and migration maintenance

Dear users,

The default standard environment has changed to Debian 13 for some

selected clusters over the past few weeks.

Here they are:

grenoble : vercors4 (3 nodes)

lyon  : hydra (4 nodes)

sophia  : esterel10 (3 nodes)

nancy  : grouille (2 nodes)

louvain  : spirou (8 nodes)

This is a key step towards the widespread deployment of Debian13. Most

clusters will be switched to a Debian 13 default environment Wednesday 26 August 2026.

If you need to, all the variants images (min, nfs, big) are available

for deployment, see `kaenv3 -l debian%13%` on frontends to list them.

Remember that there is a significant change concerning the modules. See

the preview announce : https://www.grid5000.fr/w/News#Upcoming_changes_to_modules

Upcoming changes to modules

Hello everyone,

Let's start with a quick TLDR, details on the rationale and implementation are available below: new modules will be available with the new standard environment, and are already live for testing (but not activated by default).

If you want to test them you need to run the following commands:

unset MODULEPATH

module use /grid5000/guix-modules/x86_64/latest
/grid5000/spack/module-others

Now for more details: for the past months we have been working on updating the standard environment and the way we provide modules.

The current way uses Spack under the hood, and is tightly bound to the underlying operating system.

It's been proven to be quite a burden for the team, and therefore we are changing the way we manage modules to:

- use a solution oblivious to the Linux flavor; - have means to update software versions automatically, and a clear release cycle; - actually have something reproducible; - be able to automatically test our most sensitive modules when they change (on both OAR and SLURM clusters).

Under the hood we switched to Guix to manage them²; it will be totally transparent for you.

The upcoming modules are located in `/grid5000/guix-modules/x86_64`, and you can try them today!

In order to use them you need to perform the following commands¹:

unset MODULEPATH

module use /grid5000/guix-modules/x86_64/latest

The list of modules for the `latest` release is available here:

https://api.grid5000.fr/explorer/software.

We know it's missing a few software compared to the current modules, we've tracked them here.

These should be available shortly, at least before we actually switch the default modules.

We intend to have a release at least every 4 months, providing updates to our software catalog.

If software needs to be added/updated we may of course perform a release.

We also intend to keep the past 5 releases directly available so that you may go back to use a previous release if needed. Should you ever really need to, the admin team (or even y...
