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

[Tao.3.Chen@xxxxxxxxxxxxxxxxxxxxxxxxxxx]

Hi,Kent,
   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?

Tao

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 
(http://www.cs.wisc.edu/condor/manual/v7.2/3_4User_Priorities.html#23967)?

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.
