Re: [HTCondor-users] Job Scheduling

[Muak rules <muakrules@xxxxxxxx>]

Hello

yes 10.0.0.1 is the IP address of pucitServer.CentOSWorld.com

Please correct me if I'm wrong. All I'm getting from your answer is that we have to make configuration in /etc/condor/condor_config.local.

But in the following blog it is mentioned that we have to make configuration in /etc/condor/condor_config.

http://spinningmatt.wordpress.com/2011/06/12/getting-started-creating-a-multiple-node-condor-pool/

These are two different files where should I need to configure for scheduling my job from master to workers machines.

Greetings....
