Latest news

Cluster Spirou is now in default queue at Louvain

We are pleased to announce that the Spirou[1] cluster of the newly installed Louvain site is now available in the default queue.

Spirou is a cluster composed of 8 Lenovo ThinkSystem SR630 V2 nodes, each featuring:

2x CPU Intel Xeon Gold 5318Y (Ice Lake-SP)24 cores/CPU

256 GiB RAM

1x 4.0 TB HDD SATA Lenovo

2x 100Gbps Mellanox network interface

Be aware that we noticed I/Os inconsistencies on this cluster.

We advise users to take this into account when performing experimentations on the cluster. See the following bug for more information: https://intranet.grid5000.fr/bugzilla/show_bug.cgi?id=16938

This cluster was funded by the Fonds de la Recherche Scientifique – FNRS (F.R.S.–FNRS), and its operation is supported by F.R.S.–FNRS and the Wallonia region (SPW).

End of support for centOS7/8 and centOSStream8 environments

Support for the centOS7/8 and centOSStream8 kadeploy environments is stopped due to the end of upstream support and compatibility issues with recent hardware.

The last version of the centOS7 environments (version 2024071117), centOS8 environments (version 2024071119), centOSStream8 environments (version 2024070316) will remain available on /grid5000. Older versions can still be accessed in the archive directory (see /grid5000/README.unmaintained-envs for more information).

Ecotaxe cluster is now in default queue at Nantes

We are pleased to announce that the ecotaxe cluster of Nantes is now available in the default queue.

As a reminder, ecotaxe is a cluster composed of 2 HPE ProLiant DL385 Gen10 Plus v2 servers[1].

Each node features:

2 AMD EPYC 7453 (Zen 3), 28 cores/CPU

3 Nvidia A100 80GB GPU

256 GB memory

1x 1.92 To SSD + 2x 7.68 To SSD

100 Gb/s Intel Ethernet adapter [2].

To submit a job on this cluster, the following command may be used:

oarsub -t exotic -p ecotaxe

This cluster is co-funded by Région Pays de la Loire, FEDER and REACT EU via the CPER SAMURAI [3].

Some changes on the hardware configuration of Grenoble nodes

We recently did some 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.
