Both of the above mentioned settings are set.
This is the output. (1 node, 4 cores. The same job of 4 cores is submitted
multiple times)
# qstat -u "*" -urg
job-ID prior nurg urg rrcontr wtcontr dlcontr name user
state submit/start at deadline queue

Here I did understand the values of "urg". But not getting how "nurg" is
calculated.
# qstat -u "*" -ext
job-ID prior ntckts name user project department
state cpu mem io tckts ovrts otckt ftckt stckt share queue
slots ja-task-ID

In this output why the value of tckts is getting changed? 100, 50, 33.
sharetree has 100 shares.
