Latest news
Troll and Gemini clusters are now exotic resources (change in the way to reserve them)
Clusters Troll on Grenoble and Gemini on Lyon are now considered exotic resources, and must be reserved using the exotic OAR job type.
When a cluster on Grid'5000 has a hardware specificity that makes it too different from a "standard" configuration, it is reservable only using the exotic OAR job type. There are 2 reasons for this:
- It ensures that your experiment won't run on potentially incompatible hardware, unless you explicitly allow it. (for example, you don't want to get a aarch64 cluster if your experiment is built for x86)
- By not allocating these resources to jobs by default, it makes them more easily available for users who are looking specifically for this kind of hardware.
There is an example of usage of the exotic job type in the getting started : https://www.grid5000.fr/w/Getting_Started#Selecting_specific_resources
You can see if a cluster is exotic in the reference API or on the Hardware page of the wiki : https://www.grid5000.fr/w/Hardware#Clusters
There are currently 4 clusters which needs the exotic job type to be reserved :
- pyxis because it has a non-x86 CPU architecture (aarch64)
- drac because it has a non-x86 CPU architecture (ppc64)
- troll because it has PMEM ( https://www.grid5000.fr/w/PMEM )
- gemini because it has 8 V100 GPU per node, and only 2 nodes

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.
