* <tt>Resources</tt>ː The cluster is simply very busy and you will have to be patient or perhaps consider if you can submit a job that asks for fewer resources (e.g. CPUs/nodes, GPUs, memory, time). | * <tt>Resources</tt>ː The cluster is simply very busy and you will have to be patient or perhaps consider if you can submit a job that asks for fewer resources (e.g. CPUs/nodes, GPUs, memory, time). | ||
* <tt>Priority</tt>ː Your job is waiting to start due to its lower priority. This is because you and other members of your research group have been over-consuming your fair share of the cluster resources in the recent past, something you can track using the command <tt>sshare</tt> as explained in [[Job scheduling policies]]. | * <tt>Priority</tt>ː Your job is waiting to start due to its lower priority. This is because you and other members of your research group have been over-consuming your fair share of the cluster resources in the recent past, something you can track using the command <tt>sshare</tt> as explained in [[Job scheduling policies]]. The <tt>LevelFS</tt> column gives you information about your over- or under-consumption of cluster resources: when <tt>LevelFS</tt> is greater than one, you are consuming fewer resources than your fair share, while if it is less than one you are consuming more. The more you overconsume resources, the closer the value gets to zero and the more your pending jobs decrease in priority. There is a memory effect to this calculation so the scheduler gradually "forgets" about any potential over- or under-consumption of resources from months past. Finally, note that the value of <tt>LevelFS</tt> is unique to the specific cluster. | ||
