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. ÂÂIt 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.
Â
Try
Â
 ps aux | grep -I condor_startd
Â
or maybe
Â
 condor_off -startd
Â
If you have multiple startds, the condor_off will probably turn off only one of them, so wait a bit and then try
Â
condor_status again.

Hi John,
Â
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:
Â
mmxlabs@kubera:/etc/condor$Â Â condor_status -af myaddress

Do you maybe have multiple startdâs reporting to a single collector?
Â
Try
Â
ÂÂ condor_status -af myaddress
Â
You should get the same value for all the slots if they are all coming from a single startd.
Â
Or maybe something is overriding your config?
Â
Try this:
Â
condor_config_val -startd -verbose -dump NUM_SLOTS
Â
Does it still show NUM_SLOTS=2 ?

Subject: [HTCondor-users] Personal HTCondor Install - how to reduce number of slots?Â
Hi All,
Â
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.
Â
E.G. I have the following in condor_config.local settings:
NUM_SLOTS=2
Â
For a while condor_status show:
Â
mmxlabs@kubera:/etc/condor$ condor_status
Name        OpSys   Arch  State   Activity LoadAv Mem  ActvtyTime
Â
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

Â
       Total   2   0    0     2    0     0    0
Â
After a little while (i.e. 3 minutes) extra slots appear:
Â
mmxlabs@kubera:/etc/condor$ condor_status
