Re: [HTCondor-users] Master Daemon

[kschwarz@xxxxxxxxxxxxxx]

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!).
 
 
DAEMON_LIST=MASTER
SCHEDD STARTD KBDD
 
For my central manager I
have:
 
DAEMON_LIST=MASTER SCHEDD
COLLECTOR NEGOTIATOR STARTD KBDD
 
Am I doing it right?
 
Andrew
