The Nancy Grid'5000 site also hosts nodes for production use. Those nodes are:
* {{Act|Clément|décrire précisément le matériel}}
 
The usage rules differ from the rest of Grid'5000:
* Advance reservations (<code>oarsub -r</code>) are not allowed (to avoid fragmentation). Only submissions (and reservations that start immediately) are allowed.
* All Grid'5000 users can use those nodes, but it is expected that users outside of LORIA / Inria Nancy -- Grand Est will use their own local production resources in priority, and mostly use those resources for tasks that require Grid'5000 features. Examples of local production clusters are Tompouce (Saclay), Igrida (Rennes), Plafrim (Bordeaux), etc.

Most likely, this is because of our configuration of resources restriction per walltime.
In order to make sure that someone requesting only a few nodes, for a small amount of time will be able to get soon enough, the nodes are split into categories:
* 20% of the nodes only accept jobs with walltime lower than 1h
* 20% -- 2h
* 20% -- 24h
* 20% -- 48h
* 20% accept all jobs (no limit on duration)
Note that ''best-effort'' jobs are excluded from those limitations.
 
Another OAR setting could impact the scheduling of your jobs. The OAR ''karma'' feature is enabled: this feature assigns a dynamic priority to submissions based on the history of submissions by a specific user. With that feature, the jobs from users that rarely submit jobs will be generally scheduled earlier than jobs from heavy users.
 
== I have an important demo, can I reserve all resources in advance? ==
There's a special ''challenge'' queue that can be used to combine resources from the classic Grid'5000 clusters and the production clusters for special events. If you would like to use it, please get in touch with the clusters managers.
