    NAME
         sge_schedd - Grid Engine job scheduling agent

    SYNOPSIS
         sge_schedd [ -help ]

    DESCRIPTION
         sge_schedd computes the scheduling decision in a Grid Engine
         cluster.  The  information  necessary  for  the  decision is
         retrieved from sge_qmaster(8) via an event interface.  After
         applying  the  scheduling algorithm, sge_schedd communicates
         the scheduling decision back to sge_qmaster(8) again via the
         Grid  Engine  GDI.  In  order  to  trigger a sge_schedd run,
         sge_qmaster(8) samples changes in  the  cluster  status  and
         notifies sge_schedd in periodical time intervals.
         Together  with  sge_schedd  a  sge_commd(8)  is  brought  up
         automatically on the same machine (if not already present).

         By using the -tsm option of the qconf(1) command, sge_schedd
         can be forced to print trace messages of its next scheduling
         run to the file <sge_root>/<cell>/common/schedd_runlog.  The
         messages  indicate the reasons for jobs and queues not being
         selected in that run

    OPTIONS
         -help
              Print version number of the scheduler.

    ENVIRONMENTAL 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_schedd 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.

         COMMD_PORT     If set,  specifies  the  tcp  port  on  which
                        sge_commd(8)   is   expected  to  listen  for
                        communication requests.   Most  installations
                        will  use  a  services  map  entry instead to
                        define that port.
