sge_qmaster - Grid Engine master control daemon
sge_qmaster [ -help ]
sge_qmaster controls the overall Grid Engine behavior in a cluster.
- Prints a listing of all options.
- Specifies the location of the Grid Engine standard configuration
- 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.
- 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.
- If set, the qmaster will not daemonize.
- If set, specifies the tcp port on which sge_qmaster(8) 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.
- If set, specifies the tcp port on which sge_execd(8) is expected to
listen for communication requests. Most installations will use a services
map entry for the service "sge_execd" instead to define that
- If set, specifies a delay in (integral seconds) before a scheduling run,
for test purposes.
- If set, don't daemonize the program (for debugging).
- 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.
On Solaris, coreadm(1) may be used to enable such dumps.
- 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 bootstrap(5)).
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.
