NAME

       sge_qmaster - Grid Engine master control daemon

SYNOPSIS

       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 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.

       SGE_EXECD_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 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.
                      On Solaris, coreadm(1) may be used to enable such dumps.

       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 bootstrap(5)).

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

       <sge_root>/<cell>/common/configuration
                       Grid Engine global configuration
       <sge_root>/<cell>/common/local_conf/<host>
                       Grid Engine host specific configuration
