Grid'5000

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

Some changes on the hardware configuration of Grenoble nodes

We recently did somes hardware changes on clusters yeti, troll and dahu.

The changes are as follows:

yeti :

Following a malfunction of the two NVMe disks on yeti-3, an NVMe disk from yeti-1 has been transferred to yeti-3 to ensure that we have at least one functional NVMe disk per yeti node. New NVMe configuration of the nodes:

yeti-[1,3]: 1× NVMe
yeti-[2,4]: 2× NVMe

troll :

Due to experimentation needs, the steering committee agreed to change the hardware configuration of the troll cluster, replacing the Omnipath HPC network interconnect (interconnecting troll to yeti and dahu) by the Infiniband HPC network interconnect already available for the drac cluster.

dahu :

A few nodes of the dahu cluster recently encountered a recurrent problem with their OPA interfaces. Instead of fully retiring those nodes, we chose to disable their OPA interfaces.

This change means that if you want to reserve a dahu node with OPA, you must specify it in your oarsub request. For example:

oarsub -I -p "dahu and opa_count > 0"

The nodes that have been modified are dahu-18, dahu-26 and dahu-30. More nodes may be added to this list in the future.

Cluster "clervaux" is now in the default queue in Luxembourg

We are pleased to announce that the clervaux[1] cluster of Luxembourg is now available in the default queue.

Clervaux is a cluster composed of 48 CPU nodes.

Each node features:

2x CPU Intel Xeon E5-2680 v4 (14 cores/CPU, 2 threads/cores)

128 GiB RAM

1x 120GB SSD SATA disk

This cluster was funded by the University of Luxembourg.

End of support for Debian10 environments

Support for the debian10/buster kadeploy environments is stopped due to the end of upstream support and compatibility issues with recent hardware.

The last version of the debian10 environments (version 2025082716) will remain available on /grid5000. Older versions can still be accessed in the archive directory (see /grid5000/README.unmaintained-envs for more information).
