A quality of service or QOS is a set of parameters which are associated with job. The QOSs available, together with the properties they define, can be seen via the command
sqos. A QOS can increase the priority of a job, but this will be offset by a reduction in the maximum run-time of the job. In addition, only a certain number of jobs per user can be run or submitted in a given QOS. The QOS can be set by using the following in the submit script:
Thus it is possible to start a test job in the partition 'main' with the QOS 'short' which runs on a large number of nodes. Please note that a limit, such as
TimeLimit, set by the QOS will override that set by the partition.
