Re: [Condor-users] FW: configuring policies to obtain first come, first serve queue

["Alas, Alex [FEDI]" <aalas@xxxxxxxxxxxxx>]

Ian,

Yes, we do have a controlled submission interface, one of our developers created a small gui interface that creates the submitting file and also submits the jobs to our negotiator machine, in an effort to standardize the submitting process but jobs are launched from different machines, so for your second question: NO, we don’t have one schedd, we have several machines which their only role of being submitter machines, interpreting that schedd is a system that submit and schedule jobs so I will infer that is what you meant when you asked (you have only one schedd in your pool?). I guess the only way to get around to obtain an scenario where jobs are processed accordingly will be by prioritizing the jobs, the question here lies in a previous question I formulate to you, I think, is on how to work with the different priority options condor gives you?

Thank you for your input and for your future response,

Respectfully,

Alex

Do you control your submission interface? Do you have only one schedd in your pool?

 

If both of these things are true you can try putting all jobs in the same accounting group. That would have the effect of making everyone’s submissions to Condor get treated almost as if they always come from the same person. (That’s a gross simplification of what accounting groups do on part) For a single user’s jobs on one schedd Condor is going to consider clusters in the order they were submitted if all clusters have the same priority.

 

Accounting groups are explained here: http://www.cs.wisc.edu/condor/manual/v7.0/3_4User_Priorities.html#18780

 

If you have multiple schedds I’m not entirely certain this would work. Condor, last I looked, schedules all jobs for one schedd daemon, then the next, then the next, then the next, etc. But that may have changed. Last I looked at this code was around the 6.8.x time frame.

Guys,

I forgot to mentioned that all my condor startd and negotiator machines are windows systems, 4 windows 2003 boxes with 4 cpu’s each, and 3 Windows XP boxes with 2 cpu’s each, to make a total of 22 CPU in total. My apologies for the typo mistake: : “I don’t know have no idea”, I wanted to say “I have no Idea how to set that up?”

Thanks again for your input,

Alex

Hello to  all  of you,

I have a request from some of my condor users, they want to see if there is a way to configure my condor pool to process jobs in a first come, first serve basis but I don’t know have no idea of how to set that up?

Thanks in advance for your input,

 

Respectfully,

Alex Alas
