Re: [HTCondor-users] Master Daemon

Hi Andrew,

Yes you are doing right!
Master daemon is the daemon that is responsible for keeping all the rest of the HTCondor daemons running on each machine in the pool, so each machine in a HTCondor pool must have this daemon running no matter what functions the machine performs.
The first line you wrote is for an executer and submitter node.
The Central Manager should have at least the MASTER, COLLECTOR and NEGOTIATOR to perform the CM functions: collect all ClassAds (COLLECTOR) and perform the matchmaking (NEGOTIATOR). The line you wrote adds the Scheduler and Executer functions to that machine.
Always you have a machine with STARTD running you should also have a KBDD daemon to monitor the keyboard/mouse activity. On Windows machines you will also see an KBDD running under the user login that monitors that user keyboard/mouse activity.

More informations about MASTER you could find at http://condor-portal/manuals/html/condor-V8_0_2-Manual/3_1Introduction.html#8881

Please excuse my ignorance, but which computers should be running the master daemon – i.e. if I have a node that can submit and execute (but is not the central manager) should it be running the master daemon? I don’t find the documentation particularly helpful on this, at least, not in the locations I have looked (which is almost certainly not the right ones!).
For my central manager I have:
Am I doing it right?
