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

[Alex Churchill <alex.churchill@xxxxxxxxxxxxxxx>]

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

ÂÂ Â Â Â Â Â Â Â Â Â 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:

mmxlabs@kubera:/etc/condor$ condor_status
