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

                       Grid Engine host specific configuration
