Re: [Condor-users] Restrict pool to a single submit machine

[uni-ulm.m.roehm@xxxxxxxxxxxxxxxxxxx]

Hi Pascal,

as far as I know this shouldn't be a
problem. You could set up one machine as a "Submit node", one
as a "Central Manager node" and all the others to be "Execute
nodes" (http://www.cs.wisc.edu/condor/manual/v6.8/3_1Introduction.html#SECTION00411000000000000000).
In the config file you can do this as follows:

Central Manager Node:    
   DAEMON_LIST   = MASTER, COLLECTOR, NEGOTIATOR,
STARTD
Submit Node:        
       DAEMON_LIST  = MASTER, SCHEDD
Execute Node:        
       DAEMON_LIST   = MASTER, STARTD

See the Condor Admininstrator manual
for more information.
