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

Latest news

Rss.svgDebian 11 "Bullseye" preview environments are now available for deployments

Debian 11 stable (Bullseye) will be released in a few weeks. We are pleased to offer a "preview" of kadeploy environments for Debian 11 (currently still Debian testing), that you can deploy already. See the debian11 environments in kaenv3.

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

In particular, it includes many software updates:

  • Cuda 11.2 / Nvidia drivers 460.73.01
  • OpenJDK 17
  • Python 3.9.2
    • python3-numpy 1.19.5
    • python3-scipy 1.6.0
    • python3-pandas 1.1.5

(Note that Python 2 is not included as deprecated since Jan. 2020 and /usr/bin/python is symlinked to /usr/bin/python3)

  • Perl 5.32.1
  • GCC 9.3 and 10.2
  • G++ 10.2
  • Libboost 1.74.0
  • Ruby 2.7.3
  • CMake 3.18.4
  • GFortran 10.2.1
  • Liblapack 3.9.0
  • libatlas 3.10.3
  • RDMA 33.1
  • OpenMPI 4.1.0

Known regressions and problems are :

  • The std environment is not ready yet, and will not be the default Grid'5000 environment until official Debian 11 Bullseye release.
  • Cuda/Nvidia drivers do not support - out-of-the-box or at all - some quite old GPUs.
  • BeeGFS is not operational at the moment.

Let us know if you want us to support some tools, softwares,… that are not available on big images.

As a reminder, you can use the following commands to deploy an environment on nodes (

 $ oarsub -t deploy -I
 $ kadeploy3 -e debian11-x64-big...

Rss.svgKadeploy: use of UUID partition identifiers and faster deployments

Up to now, kadeploy was identifying disk partitions with their block device names (e.g. /dev/sda3) when deploying a system. This no longer works reliably because of disk inversion issues with recent kernels. As a result, we have changed kadeploy to use filesystem UUIDs instead.

This change affects the root partition passed to the kernel command line as well as the generated /etc/fstab file on the system.

If you want to keep identifying the partitions using block device names, you can use the "--bootloader no-uuid" and the "--fstab no-uuid" options of g5k-postinstall, in the postinstalls/script of the description of your environment. Please refer to the "Customizing the postinstalls" section of the "Advanced Kadeploy" page: Advanced_Kadeploy#Using_g5k-postinstall

As an additional change, Kadeploy now tries to use kexec more often, which should make the first deployment of a job noticeably faster.

Rss.svgNew monitoring service with Kwollect is now stable

The new Grid'5000 monitoring service based on Kwollect is now stable. Kwollect will now serve requests adressed to Grid'5000 "Metrology API", i.e., from this URL:

The former API based on Ganglia is no longer available, and Ganglia will be removed from Grid'5000 environments starting from the next Debian version (debian11).

Main features of Kwollect are:

  • Focus on "environmental" monitoring, i.e. metrics not available from inside the nodes: electrical consumption, temperature, metrics from network equipments or nodes' BMC… but Kwollect also monitors node's metrics from Prometheus exporters
  • Support for Grid'5000 wattmeters at high frequency
  • On-demand activation of optional metrics
  • Custom metrics can be pushed by users
  • Grafana-based vizualisation

Its usage of this new service is described at: Monitoring_Using_Kwollect

Here are the main other changes since the last annoucement on December:

  • Monitoring related entries in Reference API have been cleaned (nodes' "sensors" and "wattmetre" keys removed, "pdu" moved at top level), OAR property wattmeter=SHARED and wattmeter=MULTIPLE removed
  • Visualization now uses Grafana
  • Metrics naming and polling period have been updated
  • Grid'5000 documentation has been updated
  • Bugs and performance fixes

Rss.svgUpgrade of the graffiti-13 node in Nancy

We are happy to announce that the graffiti-13 node on the Nancy site in production queue has been upgraded:

its 4 GeForce RTX 2080 Ti 11GB have been replaced by 4 RTX 6000 24GB GDDR6[1].

Reservation example : oarsub -q production -p "host=''" -I
