Latest news
100 Gbps Omni-Path network now available
Omni-Path networking is now available on Nancy's grele and grimani clusters.
On the software side, support is provided in Grid'5000 environments using packages from the Scibian distribution[0], a Debian-based distribution for high-performance computing started by EDF.
OpenMPI automatically detects and uses Omni-Path when available. To learn more about how to use it, refer to the Run MPI on Grid'5000 tutorial[1].
More new clusters with Omni-Path networks are in the final stages of installation. Stay tuned for updates!

During this week, we will change the access policy of home directories in order to improve the security and the privacy of data stored in your home directory.
This change should be transparent to most users, as:
- You will still have access to your local user home from reserved nodes when using the standard environment or when deploying custom environments such as 'nfs' or 'big'.
- You can still access every user's home from frontends (provided the access permissions allow it).
However, in other situations (give access to your home to other users, mount home directory from another site or inside a virtual machine or from a VLAN, ...), you will need to explicitely allow access using the new Storage Manager API. See https://www.grid5000.fr/w/Storage_Manager
Note that this change requires a switch to autofs to mount /home in user environments. This should be transparent in most cases because g5k-postinstall (used by all reference environments) has been modified. However, if you use an old environment, it might require a change either to switch to g5k-postinstall, or to switch to autofs. Contact us if needed.

New cluster in Nantes: ecotype
We have the pleasure to announce a new cluster called "ecotype" hosted at the IMT Atlantique campus located in Nantes. It features 48 Dell Powerdege R630 nodes with 2 Intel Xeon E5-2630L v4, 10C/20T, 128GB DDR4, 372GB SSD and 10Gbps Ethernet.
This cluster has been funded by the CPER SeDuCe (Regional concil of the Pays de la Loire, Nantes Metropole, Inria Rennes - Bretagne Atlantique, IMT Atlantique and the French government).

New production cluster in Nancy: grvingt
We are happy to announce that a new cluster with 64 compute nodes and 2048 cores is
ready in the *production queue* in Nancy !
This is the first Grid'5000 cluster based on the latest generation of Intel CPUs (Skylake).
Each node has:
- two Intel Xeon Gold 6130 (Skylake, 2.10GHz, 2 CPUs/node, 16 cores/CPU)
- 192GB of RAM
- 1TB HDD
- one 10Gbps Ethernet interface
All nodes are also connected with an Intel Omni-Path 100Gbps network (non-blocking).
This new cluster, named "grvingt"[0], is funded by CPER CyberEntreprises (FEDER, Région Grand Est, DRRT, INRIA, CNRS).
As a reminder the specific rules for the "production" queue are listed on
https://www.grid5000.fr/w/Grid5000:UsagePolicy#Rules_for_the_production_queue
[0] Important note regarding pronunciation: despite the Corsican origin, you should pronounce the trailing T as this is how "vingt" is pronounced in Lorraine.
