NAME¶
sge_qmaster - Grid Engine master control daemonSYNOPSIS¶
sge_qmaster [ -help ]DESCRIPTION¶
sge_qmaster controls the overall Grid Engine behavior in a cluster.OPTIONS¶
- -help
- Prints a listing of all options.
ENVIRONMENT VARIABLES¶
- SGE_ROOT
- Specifies the location of the Grid Engine standard configuration files.
- SGE_CELL
- If set, specifies the default Grid Engine cell. To address a Grid Engine cell sge_qmaster uses (in order of precedence):
The name of the cell specified in the environment
variable SGE_CELL, if it is set.
The name of the default cell, i.e. default.
- SGE_DEBUG_LEVEL
- If set, specifies that debug information should be written to stderr. In addition, the level of detail in which debug information is generated is defined by the defined value.
- SGE_DEBUG_LEVEL
- If set, the qmaster will not daemonize.
- SGE_QMASTER_PORT
- If set, specifies the tcp port on which is expected to listen for communication requests. Most installations will use a services map entry for the service "sge_qmaster" instead to define that port.
- SGE_EXECD_PORT
- If set, specifies the tcp port on which is expected to listen for communication requests. Most installations will use a services map entry for the service "sge_execd" instead to define that port.
- SGE_TEST_DELAY_SCHEDULING
- If set, specifies a delay in (integral seconds) before a scheduling run, for test purposes.
- SGE_ND
- If set, don't daemonize the program (for debugging).
- SGE_ENABLE_COREDUMP
- If set, enable core dumps on Linux when the admin_user is not root. Linux
normally disables core dumps when the daemon has changed uid or gid.
Setting SGE_ENABLE_COREDUMP in sge_qmaster's environment defeats that to
enable core dumps for debugging if they are otherwise allowed. This is
typically not a big hazard with SGE, since most information is exposed in
the spool area anyhow. Dumps will appear in the host spool directory.
- SGE_QMASTER_PIDFILE
- Path name of file to which to write the daemon process id at startup (default "qmaster.pid"). Note that this must be writable by the admin user (see
RESTRICTIONS¶
sge_qmaster is usually started from root on the master or shadow master machines of the cluster. If started by a normal user, a master spool directory must be used to which the user has read/write access. In this case only jobs being submitted by that same user are handled correctly by the system.FILES¶
