Re: [HTCondor-users] Personal HTCondor Install - how to reduce number of slots?

[John M Knoeller <johnkn@xxxxxxxxxxx>]

Do you maybe have multiple startdâs reporting to a single collector?

 

Try

 

   condor_status -af myaddress

 

You should get the same value for all the slots if they are all coming from a single startd.

 

Or maybe something is overriding your config?

 

Try this:

 

condor_config_val -startd -verbose -dump NUM_SLOTS

 

Does it still show NUM_SLOTS=2 ?

Subject: [HTCondor-users] Personal HTCondor Install - how to reduce number of slots?

 

Hi All,

 

I have been using condor in the âpersonal installâ setting for a while on version 8.0.5, and could happily control number of slots and cpu by modifying condor_config.local. However, I have recently installed 8.4.2 on Ubuntu through apt-get and the personal setting appears to always use as many slots as cpus.

 

E.G. I have the following in condor_config.local settings:

NUM_SLOTS=2

 

For a while condor_status show:

 

mmxlabs@kubera:/etc/condor$ condor_status

Name               OpSys      Arch   State     Activity LoadAv Mem    ActvtyTime

 

slot1@kubera       LINUX      X86_64 Unclaimed Benchmar  0.000 64426  0+00:00:04

slot2@kubera       LINUX      X86_64 Unclaimed Idle      0.000 64426  0+00:00:05

                     Total Owner Claimed Unclaimed Matched Preempting Backfill

 

        X86_64/LINUX     2     0       0         2       0          0        0

 

               Total     2     0       0         2       0          0        0

 

After a little while (i.e. 3 minutes) extra slots appear:
