Good afternoon, Thanks to every body for your help, finally I got it running, but now I have another question: I'd define two slot types, SLOT_TYPE_1 with 2/8 of total resources and SLOT_TYPE_2 with 1/8 of total resources, I add 1 TYPE_1 slot and 6 TYPE_2 slots. Now I want to prevent Condor to use slot1 (the SLOT_TYPE_1 slot) is there a way to do this?
Append this to your condor configuration: START = ($(START)) && SlotId != 1 --Dan
This is the condor_status output: Name OpSys Arch State Activity LoadAv Mem ActvtyTime slot1@xxxxxxxxxxxx LINUX X86_64 Owner Idle 0.010 8012 0+00:10:04 slot2@xxxxxxxxxxxx LINUX X86_64 Unclaimed Idle 0.000 4006 0+02:20:06 slot3@xxxxxxxxxxxx LINUX X86_64 Unclaimed Idle 0.000 4006 0+02:20:07 slot4@xxxxxxxxxxxx LINUX X86_64 Unclaimed Idle 0.000 4006 0+02:20:08 slot5@xxxxxxxxxxxx LINUX X86_64 Unclaimed Idle 0.000 4006 0+02:20:09 slot6@xxxxxxxxxxxx LINUX X86_64 Unclaimed Idle 0.000 4006 0+02:20:10 slot7@xxxxxxxxxxxx LINUX X86_64 Unclaimed Idle 0.000 4006 0+02:20:11 I want to do this, because the our master/submit node have 8 cores and we want to process tasks in the other cores while we sent jobs from the same server without produce a job's preemption.

The default assumption is that jobs are well-behaved and will only use as many resources as advertised in their ClassAd. If you wish to restrict the job running in slot X to only use core X, you can use ENFORCE_CPU_AFFINITY. --Dan On 6/28/11 10:17 AM, Lukas Slebodnik wrote:Another approch is set variable NUM_CPUS, it can be used to lie to the condor_startd daemon about how many CPUs a machine has. After setting this variable Condor must be restarted. Reconfiguration using condor_reconfig will not be enough. http://www.cs.wisc.edu/condor/manual/v7.4/3_3Configuration.html#16457 NUM_CPUS = 6 Regards, Lukas On Tue, Jun 28, 2011 at 11:10:05AM -0400, Ian Chesal wrote:On Tuesday, June 28, 2011 at 11:00 AM, Edier Zapata wrote:Good morning, Is there a way to avoid the use of X cores by Condor? Example: I have a 8 cores node, but I want Condor to use only the cores 3 to 8 and have cores 1 and 2 free of Condor's processing. Is there a way to do this?Add: NUM_SLOTS = 6 to the condor_config.local file for the machine and it will only advertise 6 slots instead of 8. That's the quick way to do it. If you want 1/8th of the memory per slot instead of 1/6th you need to define a new slot type: SLOT_TYPE_1 = 1/8 NUM_SLOTS_TYPE_1 = 6 NUM_SLOTS = 6 I think you need the NUM_SLOTS in there still to keep Condor from using the 2 additional CPUs you didn't use with TYPE_1 -- play around with that one. It's been a while since I divided things any way other than evenly.
