We are implementing as our Resource Manager the Sun Grid Engine v6 ( N1GE6)
(Not Enterprise Edition), and as part of that I am trying to understand how
to establish the priority of a job submitted in one queue, over a job
submitted earlier in a different queue.
I have setup the following configurations on my laptop using VMWare with
RedHat and the Grid Engine.
If I have two queues configured, with the only difference being the
priority, and the queue name. The modified values from the defaults are
Parameter Queue 1 Queue 2
qname Queue1 Queue2
hostlist RedHatLocal RedHatLocal
priority 20 -20
slots 1 1
- For the single execution host (RedHatLocal), the only modification to the
execution host is to give it a slots value of 1 to make it easy to track
which jobs are being sent through to it from the queues (complex_values
- I have also modified the scheduler configuration (qconf -msconf) setting
reprioritize_interval to 0:0:3.
What I am expecting is that if I have a number of pending jobs for Queue1,
if I then submit a job explicitly to Queue2, that the job submitted to
Queue2 should be the next job to run. However this is not the behaviour
that I see. What I am seeing is the jobs being executed in their sequential
Does anyone have any thoughts?
