NAME

       sge_qmaster - Sun Grid Engine master control daemon

SYNOPSIS

       sge_qmaster [ -help ]

DESCRIPTION

       sge_qmaster controls the overall Sun Grid Engine behavior in a cluster.

OPTIONS

       -help  Prints  a listing of all options.

ENVIRONMENTAL VARIABLES

       SGE_ROOT       Specifies the location of the Sun Grid  Engine  standard
                      configuration files.

       SGE_CELL       If  set,  specifies the default Sun Grid Engine cell. To
                      address a Sun Grid Engine cell sge_qmaster uses (in  the
                      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.

       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.

RESTRICTIONS

       sge_qmaster is usually started from root on the master or shadow master
       machines  of the cluster (refer to the Sun Grid Engine Installation and
       Administration Guide for more information about  the  configuration  of
       shadow  master  hosts).   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.
