Shorter command usage for Kadeploy tools

We changed the syntax of the Kadeploy commands. A typical command line for a deployment was:

 kadeploy3 -f $OAR_NODE_FILE -e debian11-x64-base -k

• The -e flag can now be omitted when deploying a recorded environment, while when deploying an anonymous deployment, the -a flag must still be set.
• The public key is copied by default, -k can be omitted.
• Nodes to be deployed are taken from $OAR_NODE_FILE if not specified on the command line with -f or -m.

As a result, the same deployment can be achieve with the following shorter command line:

 kadeploy3 debian11-x64-base

Moreover, the architectures are removed from the Grid'5000 reference environments names (eg: "debian11-x64-base" and "debian11-ppc64-base" both become "debian11-base"). Kadeploy infers the correct environment (CPU architecture) for the cluster to deploy. As a result, the previous kadeploy command line can be shortened to:

 kadeploy3 debian11-base

Old syntaxes and environment names including the architecture are however still supported for backward compatibility.

You can find more information on the Getting Started and Advanced Kadeploy pages.

Cluster "sirius" from Nvidia is available in the default queue

We have the pleasure to announce that a new cluster named "sirius" is available at Lyon.

This cluster consists in only one Nvidia DGX A100 node with 2 AMD EPYC 7742 CPUs (64 cores per CPU) and 8 Nvidia A100 (40 GiB) GPUs, 1TB of DDR4 RAM, 2x1.92 TB SSD + 4x3.84 TB SSD disks and a coming-soon infiniband network.

Energy monitoring is available for this cluster, provided by the same wattmeter devices as used for the other clusters in Lyon.

This cluster is tagged as "exotic", so the `-t exotic` option must be provided to oarsub to select sirius.

This machine has been funded by LIP laboratory with the support of INRIA Grenoble Rhone-Alpes and ENS Lyon.

Ubuntu 22.04 LTS environment available

A kadeploy environment (image) for Ubuntu Jammy Jellyfish 22.04 LTS (ubuntu2204-min) is now available and registered in all Grid'5000 sites with Kadeploy.

Only x86_64 architecture is available for now. For ARM (arm64/aarch64) and POWER 8 (ppc64/ppc64le), you can use the previous Ubuntu 20.04 LTS images (ubuntu2004-min).

Please refer to our getting started document to learn how to deploy such an image on the platform [1].

This image is built with Kameleon (just like other Grid'5000 environments). The recipe is available in the environments-recipes git repository.

If you need other system images for your work, please let us know.

End of support for Debian 9 "Stretch" environments

We are going to drop support for the stretch/debian9 environments on April 30st 2022.

The last version of strech environments i.e 2021100608 will remain available on /grid5000. You can still access older versions of debian 9 environments under the archive directory (see /grid5000/README.unmaintained-envs for more information).
