Docker cache available inside Grid5000

With the growing use of Docker, you might have experienced some rate limiting when pulling images due to the Docker Hub recent policy change.

As a result, we now provide a Docker cache accessible from inside Grid'5000 at the following address http://docker-cache.grid5000.fr

For configuration instructions and more information, see: Using docker-cache.grid5000.fr

Grid'5000 environments now use zstd compression

We are moving the default image archive format used for Grid'5000 environments from tar.gz to tar.zst. Switching to zstd allows for significantly faster decompression speed.

This change is transparent for most usages. Kadeploy will use zstd transparently for environments using it (e.g. new environments), the main impact is that deployment will be faster.

If kameleon is used to generate an environment (thus creating an environment description file and an image archive), it will now automatically use zstd by default.

However if you manually modify the description of an environment and/or regenerate an image archive with tgz-g5k (using the -z switch for zstd), you may have to make sure that both use the same compression.

This change is part of a larger effort to improve the performance of kadeploy.

Guix package manager available on Grid'5000

We now offer the possibility to use Guix on Grid'5000 as a package manager to install new software or build container images without the need to be root.

It is available on frontends and nodes (on standard or deployed *-nfs or *-big environments with your user).

This work has been done in collaboration with the Guix HPC team.

For more information see: Guix

New cluster "grouille" available in Nancy

We have the pleasure to announce that a new cluster named "grouille" is available in Nancy in the default queue.

It features 2 Dell R7525 nodes with two AMD EPYC 7452 32-Core CPUs, two NVidia A100-PCIE-40GB GPUs, 128GB of DDR-4 RAM, one 1.8TB SAS SSD and one 900GB SATA SSD (reservable). The reservation of the Grouille nodes requires using the "exotic" OAR job type.

This cluster has been funded by CPER Cyber Entreprises.
