DDEESSCCRRIIPPTTIIOONN
       _g_e___s_c_h_e_d_d  computes the scheduling decisions in an Grid Engine cluster.
       The information necessary for the decision is retrieved  from  _g_e___q_m_a_s_-
       _t_e_r(8)  via  an  event  interface.  After applying the scheduling algo-
       rithm, _g_e___s_c_h_e_d_d communicates the scheduling decision back to  _g_e___q_m_a_s_-
       _t_e_r(8)  again via the Grid Engine GDI. In order to trigger an _g_e___s_c_h_e_d_d
       scheduling run, _g_e___q_m_a_s_t_e_r(8) samples changes in the cluster status and
       periodically notifies _g_e___s_c_h_e_d_d

       By  using  the  _-_t_s_m  option  of the _q_c_o_n_f(1) command, _g_e___s_c_h_e_d_d can be
       forced to print trace messages of its next scheduling run to  the  file
       _<_g_e___r_o_o_t_>_/_<_c_e_l_l_>_/_c_o_m_m_o_n_/_s_c_h_e_d_d___r_u_n_l_o_g.  The  messages indicate the rea-
       sons for jobs and queues not being selected in that run

       --hheellpp  Print version number of the scheduler.

       GGEE__RROOOOTT        Specifies the location of the Grid Engine standard  con-
                      figuration files.

       GGEE__CCEELLLL        If  set,  specifies  the  default  Grid  Engine cell. To
                      address a Grid Engine cell _g_e___s_c_h_e_d_d uses (in the  order
                      of precedence):

                             The name of the cell specified in the environment
                             variable GE_CELL, if it is set.

                             The name of the default cell, i.e. ddeeffaauulltt.


       GGEE__DDEEBBUUGG__LLEEVVEELL 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.

       GGEE__QQMMAASSTTEERR__PPOORRTT
                      If set, specifies the tcp port on which _g_e___q_m_a_s_t_e_r(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.
