Re: [Condor-users] Fw: Problems about condor slots

Hi Dan,

 

Here is the output of the commands you want me to check out:

 

[root@node9 ~]# condor_config_val -v NUM_CPUS

Not defined: NUM_CPUS

[root@node9 ~]# condor_config_val DETECTED_CORES

4

[root@node9 ~]# condor_config_val -v COUNT_HYPERTHREAD_CPUS

Not defined: COUNT_HYPERTHREAD_CPUS

 

It seems everything is correct.

Check the output of the following commands on the machine where you see

this problem:

condor_config_val -v NUM_CPUS

condor_config_val DETECTED_CORES

condor_config_val -v COUNT_HYPERTHREAD_CPUS

I'm guessing that your LOCK directory

/tmp/condor-lock.ddgrid0.745993478763015 has been deleted. Running

condor_init should recreate it. However, I would recommend reconfiguring

LOCK to be somewhere else--not in /tmp--so it doesn't get accidentally

deleted again in the future.
