SYNOPSIS

13       condor_master
14

DESCRIPTION

16       This  daemon  is  responsible  for keeping all the rest of the HTCondor
17       daemons running on each machine in your pool. It spawns the other  dae‐
18       mons,  and  periodically  checks  to  see if there are new binaries in‐
19       stalled for any of them. If there are, the condor_master  will  restart
20       the  affected  daemons.  In  addition,  if any daemon crashes, the con‐
21       dor_master will send e-mail to the HTCondor Administrator of your  pool
22       and  restart the daemon. The condor_master also supports various admin‐
23       istrative commands that let you start, stop or reconfigure daemons  re‐
24       motely.  The  condor_master  will run on every machine in your HTCondor
25       pool, regardless of what functions each machine are performing.   Addi‐
26       tionally,  on  Linux platforms, if you start the condor_master as root,
27       it will tune (but never decrease) certain kernel  parameters  important
28       to HTCondor's performance.
29
30       The  DAEMON_LIST    configuration macro is used by the condor_master to
31       provide a per-machine list of daemons that should be started  and  kept
32       running.  For daemons that are specified in the DC_DAEMON_LIST configu‐
33       ration macro, the condor_master daemon will  spawn  them  automatically
34       appending  a  -f  argument. For those listed in DAEMON_LIST, but not in
35       DC_DAEMON_LIST, there will be no -f argument.
36
37       The condor_master creates certain directories necessary for its  proper
38       functioning  on  start-up if they don't already exist, using the values
39       of the configuration settings EXECUTE, LOCAL_DIR,  LOCAL_DISK_LOCK_DIR,
40       LOCAL_UNIV_EXECUTE,   LOCK,   LOG,  RUN,  SEC_CREDENTIAL_DIRECTORY_KRB,
41       SEC_CREDENTIAL_DIRECTORY_OAUTH, SEC_PASSWORD_DIRECTORY,  SEC_TOKEN_SYS‐
42       TEM_DIRECTORY, and SPOOL.
