[Condor-users] Antwort: Re: Antwort: Re: about different dagman jobs problem

   Thank you for your explaination, I have read the link you gave me, but I still have some quesions.
   Actually, I use remote DAGMan to submit job.In condor system, we have several users to submit dag jobs to the central manager(the remote PC) by different user account,for different dag job, as I mentioned,for each dag job of each user, I need C could be run as soon as possible after A,B finished. But actually when dag submit a new job C to condor,there are many jobs already in the queue, and they are from different users, but I want C could run as soon as possible! So my quesion is can I set priority among these different jobs from different users.
   Additionally, I use condor-c grid Universe for all the jobs, because I don't know  why if I use Vanilla Universe from central manager, all the jobs just hang on in the queue,never run.

Thank you again,because I have something emergency, can you try to help me as soon as possible?

Hmm -- I don't totally understand what you're wanting to do -- there are
user priorities, and job priorities, and they are separate.  The job
priorities (which I referred to in my previous email about the DAG
setup) only affect things within the set of jobs for a given user.
The user priorities affect how many jobs are scheduled for a given user
at a given time.

Have you looked at section 3.4 of the manual

When you say "I need to keep all users' priority the same" do you mean
that you essentially want to turn off the "fair-share" scheduling and not
change priorities based on how many jobs a user has run?  You could
pretty much do that by setting PRIORITY_HALFLIFE to a very small value
(1, say -- I'm not sure whether 0 is okay or not).

You can set user priorities with the condor_userprio command -- assuming
you have the right priviledges to do that -- you have to have Condor admin
permission to set a user's priority.
