A QOS with this flag set will not have its GrpTRESMins,
GrpWall or UsageRaw decayed by the global PriorityDecayHalfLife or
PriorityUsageResetPeriod values.  Such a QOS will act as a time-limited
quota of resources.

This flag only affects the QOS and not the associations that run in the
QOS.  Those usage values will continue to be decayed.

The only way to reset this value is with

sacctmgr mod QOS $qos set rawusage=0

If you remove the flag usage will begin to be decayed as normal.

Bug 3371.

    "Not responding".
bug 3494

Add new advanced reservation flag of "flex", which permits jobs requesting
    the reservation to begin prior to the reservation's start time and use
    resources inside or outside of the reservation. A typical use case is to
    prevent jobs not explicitlg requesting the reservation from using those
    reserved resources rather than forcing jobs requesting the reservation to
    use those resources in the time frame reserved.

Add new advanced reservation flags of "weekday" (repeat on each weekday;
    Monday through Friday) and "weekend" (repeat on each weekend day; Saturday
    and Sunday).
