Grid'5000 users survey

We are conducting a survey to help us better understand your needs and make Grid'5000 a better research infrastructure.

We thank you in advance for taking a few minutes to complete it (you can answer in French if you prefer).

The survey is available at:

https://sondages.inria.fr/index.php/672895

It will be open until December, 13rd.

New cluster "gemini" available at Lyon

We have the pleasure to announce you the availability of the new cluster "gemini" at Lyon.

Gemini includes two "Nvidia DGX-1" nodes, each with 8 Nvidia V100 GPUs, 2 Intel Xeon E5-2698 v4 @ 2.20GHz CPUs, 512GB DDR4, Infiniband EDR and 10Gbps Ethernet interfaces and 4 reservable¹ SSD disks.

Energy monitoring is also available for this cluster, provided by the same devices used for the other clusters in Lyon².

Remember that if you don't need the 8 GPUs, individual GPU may be reserved³. A script to install nvidia-docker is also available if you want to use Nvidia's images built for Docker⁴.

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

Group Storage service officially available

We are glad to announce that the Group Storage service is now no longer in beta. Additionally to the two servers in Lille, 5 storage servers in Lyon, Rennes, Nancy, Luxembourg and Sophia are now providing Group Storage volumes on demand.

See https://www.grid5000.fr/w/Group_Storage for details and https://www.grid5000.fr/w/Storage for an overview of our storage options.

New cluster available in Nancy: gros (124 nodes with reservable disks)

We have the pleasure to announce that the Gros cluster in Nancy (default queue) is now available:

It features 124 Dell R640 servers nodes with one Intel Gold 5220 (18 cores / 36 threads), 96 GB DDR4, 1x480 GB SSD + 1x960 GB reservable SSD [1] and 2x25Gbps Ethernet interfaces.

However, the installation of this cluster is not yet fully completed:

• Two nodes (gros-3 and gros-4) are in an artificial Dead state due to a kavlan issue we still have to fix with the new model of the network switches of Gros network.
• This cluster will be equipped with a high precision monitoring system for electrical power consumption (Multilab-R, from Omegawatt [2]) that is already used in Grid'5000 at Lyon [3] or Grenoble [4]. It will be available for general use by the beginning of December.
• At the present time, the uplink between the Gros cluster and the Grid5000 network operates at 10Gbs. It will improved up to 2x40Gb/s in the next month.

This cluster has been funded by the CPER Cyber Entreprises project (Contrat de plan État / Région Lorraine 2015-2020).

Again, many thanks go to the former SIC and SG services at LORIA / Inria Nancy Grand Est for their help and support during this operation.

About the name:

Gros is a french adjective which usually means large, big or fat, but when used as a noun in Lorraine (which is the region Nancy belongs to), it means something else. It is used here generally to talk about people one cares (friends, children, companions). Some examples:

• Comment que c'est gros ? (how do you do buddy ?). This is the most famous one, and we are pleased to shout it out loud when we enter into gros's server room. It seems to be spreading outside Lorraine as well[5].
• Les gros sont à l'école (children are at school)
• Wha gros c'est schteuff ! (Listen my friend, it's amazing !)
