A new version of tgz-g5k has been released

We have released a new version of tgz-g5k. Tgz-g5k is a a tool that allow you to extract a Grid'5000 environment tarball from a running node. The tarball can therefore be used by kadeploy to re-deploy the image on different nodes/reservations (see Advanced Kadeploy for more details)

The new version has two major improvements:

1. tgz-g5k is now compatible with Ubuntu and Centos
2. tgz-g5k is directly usable on frontends (you do not need to use it through ssh anymore).

To use tgz-g5k from a frontend, you can execute the following command:

  frontend$ tgz-g5k -m MY_NODE -f ~/MY_TARBALL.tgz

In case of specific or non-deployed environments: - tgz-g5k can use a specific user id to access nodes, by using the parameter -u (by default tgz-g5k accesses nodes as root) - tgz-g5k can access node with oarsh/oarcp instead of ssh/scp, by using the parameter -o (by default tgz-g5k uses ssh/scp)

Note that tg5-g5k is still compatible with the previous command line. For the record, you had to use previously the following command:

  frontend$ ssh root@MY_NODE tgz-g5k > ~/MY_TARBALL.tgz

Enabling GPU level resource reservation in OAR

We have now put in service the GPU level resource reservation in OAR in Grid'5000. OAR now allows one to reserve one (or some) of the GPUs of a server hosting many GPUs, letting the other GPUs of the server available for other jobs.

Only the reserved GPUs will be available for computing in the job, as reported by the nvidia-smi command for instance.

• To reserve one GPU in a site, one can now run: $ oarsub -l gpu=1 ...
• To reserve 2 GPUs on a host which possibly has more than 2 GPUs, one can run: $ oarsub -l host=1/gpu=2 ...
• To reserve whole nodes (servers) with all GPUs, one can still run: $ oarsub -l host=3 -p "gpu_count > 0"
• To reserve specific GPU models, one can use the "gpu_model" property in a filter: $ oarsub -l gpu=1 -p "gpu_model = 'Tesla V100'"
• One can also filter on the cluster name after looking at the hardware pages for the description of the clusters: $ oarsub -l gpu=1 -p "cluster = 'chifflet'"

Finally, please notice that the drawgantts offer options to display GPUs.

Network-level federation available between Grid'5000 and Fed4FIRE (and beyond)

It is now possible to connect Grid'5000 resources to other testbeds from Fed4FIRE. This is implemented by on-demand "stitching" between KaVLAN VLANs and VLANs provided by RENATER and GEANT that connect us to a Software Defined Exchange (SDX) hosted by IMEC in Belgium. This SDX is also connected to other SDXes in the US, which should make it possible to combine resources from Grid'5000 and US testbeds such as GENI, Chameleon or CloudLab.

For more information, see https://www.grid5000.fr/w/Fed4FIRE_VLAN_Stitching

Grid'5000 links to the Internet upgraded to 10Gbps

Thanks to Renater which provides Grid'5000 network connectivity, we just upgraded our connection to the Internet to 10Gbps.

You should experience faster downloads and an increased speed when loading your data on the platform!
