 +===== Quality of service ====
 +Access to node partitions is granted by the so-called <html><font color=#cc3300>&#x27A0; quality of service (QOS)</font></html>. The QOSs constrain the number of allocatable nodes and limit job wall time. The naming scheme of the QOSs is:
 +<project_type>_<memoryConfig>
 +
 +The QOSs that are assigned to a specific user can be viewed with:
 +<code>
 +sacctmgr show user `id -u` withassoc format=user,defaultaccount,account,qos%40s,defaultqos%20s
 +</code>
 +
 +Have a look on the <html><font color=green>&#x27A0; </font></html> [[doku:vsc3qos|available QOSs on VSC-3]].
