[1mNAME[0m
       sge_schedd - Grid Engine job scheduling agent

[1mSYNOPSIS[0m
       [1msge_schedd [22m[ [1m-help [22m]

[1mDESCRIPTION[0m
       [4msge_schedd[24m computes the scheduling decisions in an Grid Engine cluster.
       The information necessary for the decision is retrieved from  [4msge_qmas-[0m
       [4mter[24m(8)  via  an  event  interface.  After applying the scheduling algo-
       rithm,  [4msge_schedd[24m  communicates  the  scheduling  decision   back   to
       [4msge_qmaster[24m(8)  again  via  the Grid Engine GDI. In order to trigger an
       [4msge_schedd[24m scheduling run, [4msge_qmaster[24m(8) samples changes in the  clus-
       ter status and periodically notifies [4msge_schedd[0m

       By  using  the  [4m-tsm[24m  option of the [4mqconf[24m(1) command, [4msge_schedd[24m can be
       forced to print trace messages of its next scheduling run to  the  file
       [4m<sge_root>/<cell>/common/schedd_runlog[24m.  The messages indicate the rea-
       sons for jobs and queues not being selected in that run

[1mOPTIONS[0m
       [1m-help  [22mPrint version number of the scheduler.

[1mENVIRONMENTAL VARIABLES[0m
       [1mSGE_ROOT       [22mSpecifies the location of the Grid Engine standard  con-
                      figuration files.

       [1mSGE_CELL       [22mIf  set,  specifies  the  default  Grid  Engine cell. To
                      address a Grid Engine cell [4msge_schedd[24m 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. [1mdefault[22m.


       [1mSGE_DEBUG_LEVEL[0m
                      If set, specifies that debug information should be writ-
                      ten  to stderr. In addition the level of detail in which
                      debug information is generated is defined.

       [1mSGE_QMASTER_PORT[0m
                      If set, specifies the tcp port on  which  [4msge_qmaster[24m(8)
                      is  expected to listen for communication requests.  Most
                      installations will use a services map entry for the ser-
                      vice "sge_qmaster" instead to define that port.
