NAME
       sge_schedd - Grid Engine Enterprise Edition job scheduling agent

SYNOPSIS
       sge_schedd [ -help ]

DESCRIPTION
       sge_schedd computes the scheduling decision in a Grid Engine Enterprise
       Edition 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 Enterprise Edition 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 Enterprise
                      Edition standard configuration files.

       SGE_CELL       If set, specifies the default Grid Engine Enterprise
                      Edition cell. To address a Grid Engine Enterprise Edition
                      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.
