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  infor-
		      mation 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 cor-
       rectly by the system.

FILES

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