Hi Reuti,

In our cluster, we don't specify h_rt, so there is not backfill jobs and all
slots were filled out during the time I found the problem. I guess the problem
is related to that SGE reserves certain nodes for a reservation and even if
there is any other nodes are released in the mean time, SGE does not pick up
these free slots. 

Reuti> is there any other job running in the system which blocks the 16-CPU  

Reuti> job, and what you see is just the backfilling of empty slots in the  

Reuti> meantime, until the one blocking job ends?

Best regards,
