Grid'5000 is a large-scale and flexible testbed for experiment-driven research in all areas of computer science, with a focus on parallel and distributed computing including Cloud, HPC and Big Data and AI.

Key features:

  • provides access to a large amount of resources: 15000 cores, 800 compute-nodes grouped in homogeneous clusters, and featuring various technologies: PMEM, GPU, SSD, NVMe, 10G and 25G Ethernet, Infiniband, Omni-Path
  • highly reconfigurable and controllable: researchers can experiment with a fully customized software stack thanks to bare-metal deployment features, and can isolate their experiment at the networking layer
  • advanced monitoring and measurement features for traces collection of networking and power consumption, providing a deep understanding of experiments
  • designed to support Open Science and reproducible research, with full traceability of infrastructure and software changes on the testbed
  • a vibrant community of 500+ users supported by a solid technical team

Rss.svgDebian 11 "Bullseye" std environment is now the default environment on nodes

We are pleased to announce that Debian 11 (Bullseye) std environment (debian11-std) is now the default environment on nodes. See `kaenv3 -l debian11%` for an exhaustive list of available variants.

New features and changes in Debian 11 are described in: .

In particular, it includes many software updates:

  • Cuda 11.2.2 / Nvidia Drivers 460.91.03
  • OpenJDK 17
  • Python 3.9.2
    • python3-numpy 1.19.5
    • python3-scipy 1.6.0
    • python3-pandas 1.1.5
  • Perl 5.32.1
  • GCC 9.3 and 10.2
  • G++ 10.2
  • Libboost 1.74.0
  • Ruby 2.7.4
  • CMake 3.18.4
  • GFortran 10.2.1
  • Liblapack 3.9.0
  • libatlas 3.10.3
  • RDMA 33.2
  • OpenMPI 4.1.0

Some additional important changes have to be noted:

  • Python 2 is not included as it is deprecated since Jan. 2020, and `/usr/bin/python` is symlinked to `/usr/bin/python3`. Note that Python2 packages are still available on repositories and that you can install the 'python-is-python2' package to change the symlink.
  • OpenMPI
    • The OpenMPI backend used for Infiniband and Omnipath networks is UCX (this is similar to mainstream OpenMPI, but differs from the default behaviour in Debian 11).
    • The libfabric package has been recompiled to disable a buggy EFA provider (AWS)¹.
  • Apache MXNet deep learning framework is no more officially supported by the team, as his documentation.
  • As Ganglia monitoring has been replaced by Kwollect², Ganglia services have been removed from environments.
  • The BeeGFS client is not operational³, which impacts the grcinq and grvingt clusters. As a workaround, users can deplo...

Rss.svgKadeploy: Machine's architecture added to environments description

Kadeploy environments now require the architecture information in a new field named “arch” in the environment’s descriptions.

Current valid architectures on Grid’5000 are: x86_64, ppc64le (drac cluster in Grenoble), aarch64 (pyxis cluster in Lyon).

We have already added the architecture information in every recorded environment (kaenv database). If you deploy from an environment description (-a option of kadeploy), you will need to add this new field yourself. Please contact in case of issues.

If multiple environments share the same name but have different architectures, Kadeploy will automatically select the appropriate architecture for a given cluster.

Taking advantage of this new feature, the architecture code names will soon be removed from the Grid’5000 reference environments names. For instance, debian11-x64-big will become debian11-big: “x64” disappears but “x86_64” is set in the environment architecture tag.

Rss.svgCluster "neowise" from AMD is available in the default queue

We have the pleasure to announce that the "neowise" cluster is now available at Lyon in the default queue. It features 10 nodes, each including an AMD EPYC 7642 CPU with 48 cores, 8 AMD Radeon Instinct MI50 GPUs (32 GB), 512GB of RAM and an Infiniband network.

Remind that this cluster is tagged as "exotic", so the `-t exotic` option must be provided to oarsub to select neowise.

The cluster has been donated by AMD to Genci and Inria, in particular to support research against COVID-19. We would like to thank AMD for this donation and Genci for their successful collaboration in making this machine available in Grid'5000.

Rss.svgNew cluster “gruss” available in Nancy

We have the pleasure to announce that a new cluster named “gruss” is available in Nancy in the production queue. It features 4 Dell R7525 nodes with two AMD EPYC 7352 24-Cores CPUs, two NVidia A40-48GB GPUs, 256GB of DDR-4 RAM, one 1.92TB SAS SSD.

This cluster has been funded mainly by the MULTISPEECH research team (Grant from the Ministère des Armées on the application of deep learning techniques for domain adaptation in speech processing - ANR projects JCJC DiSCogs, Deep Privacy, LEAUDS, Flash Open Science HARPOCRATES), helped by the TANGRAM (ANR project Prespin) and CAPSID (H2020 ITN project RNAct) research teams.

About the name: Gruss is a well known French Circus family whose some roots [1] are in Lorraine (Nancy’s region). Strange coincidence: It happens that the Arlette Gruss Circus [2] is currently on tour in Nancy…
