Latest news
New Grid'5000 API's documentation and specification
Grid'5000 API's documentation has been updated. Before this update, the documentation contained both the specification and tutorials of the API (with some parts also present in the wiki).
To be more consistent, https://api.grid5000.fr/doc/ provides now only the specification (HTTP paths, parameters, payload, …). All tutorials were moved (along with being updated) to the Grid'5000's wiki.
The new API specification can be viewed with two tools: The first one allows to read the specification and find information ; the second one allows to discover the API thanks to a playground.
Please note that the specification may contain errors. Please report any of such errors to Support Staff.

Important changes in the privileges levels of users
Each Grid'5000 user is a member of at least one granting access group, which depends on their situation (location, laboratory, ...).
Each group is given a privilege level (bronze, silver, gold), depending on how the related organization is involved in Grid'5000's development and support.
Until now, however, these levels had no impact on how Grid'5000 could be used.
Starting from December 10th, 2020, each user will be granted different usages on the testbed depending on their privileges level. In particular:
- While every level continues to give access to the Grid'5000 default queue (most of Grid'5000 resources) ;
- Access to the production and besteffort queues will only be granted to silver and gold levels.
The complete description of each level of privileges is available here.
The privilege level of the groups a user is a member of is shown in the "group" tab of the management interface.
Note that if a user is a member of several groups, one is set as default and is implicitly used when submitting jobs.
But the "--project" OAR option can also set explicitly which group the job should use. For instance:
oarsub-I -q production --project=myothergroup
Do not hesitate to contact the Support Staff for any questions related to the privilege levels.

Reminder: Testing phase of the new monitoring service named Kwollect
As a reminder, the testing phase of Kwollect, the new monitoring solution for Grid'5000, is still ongoing.
Some new features are available since the last announcement :
- Support for Prometheus metrics
- Basic visualization dashboard
- Fine-tuning of on-demand metrics
- Ability to push your own metrics
See: Monitoring Using Kwollect
Do not hesitate to give us some feedback!
Kwollect is intended to replace the legacy monitoring systems, Kwapi and Ganglia, in the (hopefully) near future.

New IBM POWER8 cluster "drac" available for beta testing in Grenoble
We are happy to announce that a new cluster "drac" is available in the testing queue in Grenoble.
The cluster has 12 "Minsky" nodes from IBM, more precisely "Power Systems S822LC for HPC".
Each node has 2x10 POWER8 cores, 4 Tesla P100 GPU, and 128 GB of RAM. The GPUs are directly interconnected with a NVLINK fabric. Support for Infiniband 100G and kavlan is planned to be added soon.
This is the first cluster in Grid'5000 using the POWER architecture, and we are also aware of some stability issues related to GPUs, hence the "beta testing" status for now.
Feedback is highly welcome on performance and stability, as well as on our software environment for this new architecture.
Note that, since the CPU architecture is not x86, you need to explicitly ask for an "exotic" job type when reserving the nodes. For instance, to get a single GPU:
grenoble$oarsub-I -qtesting-texotic-l gpu=1
More information on the hardware is available at Grenoble:Hardware
Acknowledgment: This cluster was donated by GENCI, many thanks to them. It was formerly known as the Ouessant platform of Genci's Cellule de Veille Technologique.
