New ARM cluster "Pyxis" available on Lyon (testing queue)

We have the pleasure to announce that a new cluster named "pyxis" is available in the testing queue in Lyon.

It is the first cluster with ARM CPU (ThunderX2 9980) in Grid'5000 ! This cluster is composed of 4 nodes, each of them with 2 ThunderX2 9980 CPU (32 cores/CPU, 4 threads/cores), 256 GB RAM, 2 x 250 GB HDD, 10 Gbps Ethernet. Each node's power consumption is monitored with the wattmetre of Lyon (although it is currently broken¹). It is planned to add Infiniband network to Pyxis.

Pyxis nodes can be reserved in the testing queue (add "-q testing -p cluster='pyxis'" to your OAR submission) and arm64 environments are available to be deployed on this cluster. Beware that as it is a different CPU architecture, compiled programs targeting x86 (such as those provided by module) won't execute.

Any feedback is welcome.

This cluster has been funded by the CPER LECO++ Project (FEDER, Région Auvergne-Rhone-Alpes, DRRT, Inria).

Ubuntu 20.04 image available

A kadeploy image (environment) for Ubuntu 20.04 (ubuntu2004-x64-min) is now available and registered in all sites with Kadeploy, along with other supported environments (Centos 7, Centos 8, Ubuntu 18.04, Debian testing, and various Debian 9 and Debian 10 variants).

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

Singularity containers in Grid'5000

We now offer a better support for Singularity containers Grid'5000. It is available in the standard environment and does not require to be root.

Just run the "singularity" command to use it. It can also be run in a OAR submission (none-interactive batch job), for instance:

oarsub -l core=1 "/grid5000/code/bin/singularity run library://sylabsed/examples/lolcow"

More information about the Singularity usage in Grid'5000 is available in the Singularity page.

Singularity is a popular container solution for HPC systems. It natively supports GPU and high performance network in containers and is compatible with docker images. More info at: https://sylabs.io/docs/

Important change in the User Management System - Groups which Grant Access to the testbed

An important update to the Grid'5000 User Management System just happened. This update brings a new concept: users now get granted access to the testbed through a group membership.

These Groups which Grant Access (GGAs) allow a dispatch of the management and reporting tasks for the usage of the platform to closer managers than the Grid’5000 site managers.

Every user has to be a member of a GGA to be allowed access to the platform. The memberships are currently being worked by the staff, the site managers and new GGA managers.

You may receive emails about moves regarding your account: Don't worry. The transition to GGA should not impact your use of the platform and experimentations.

As a reminder, if you encounter problems or have questions, please report them either on the users mailing list or to the support staff, as described in the Support page. More information about this change is available in the User Management Service documentation page.
