I think you do have more than a single startd. The address you got back from condor_status

doesnât match the address of the one that condor_config_val queried. It looks like the foreign

startd is overwriting the 2 slots of the properly configured startd, and thatâs why all of the addresses are the same.

Try

ps aux | grep -I condor_startd

or maybe

condor_off -startd

If you have multiple startds, the condor_off will probably turn off only one of them, so wait a bit and then try

condor_status again.

Hi John,

Thank you for your response. If I run the two commands, it looks as though there is only one startd and the NUM_SLOTS should be 2:

mmxlabs@kubera:/etc/condor$ condor_status -af myaddress

<127.0.0.1:52708?addrs=127.0.0.1-52708>

mmxlabs@kubera:/etc/condor$ condor_config_val -startd -verbose -dump NUM_SLOTS

# Configuration from startd on kubera <127.0.0.1:3965?addrs=127.0.0.1-3965>

# Parameters with names that match NUM_SLOTS:

NUM_SLOTS = 2

# at: /etc/condor/condor_config, line 82

# expanded: 2

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:

mmxlabs@kubera:/etc/condor$ condor_status
