SGE_EXECD(8) Grid Engine Enterprise Edition Administrative Commands SGE_EXECD(8)

       sge_execd - Grid Engine Enterprise Edition job execution agent

       sge_execd [ -help ] [ -lj log_file ] [ -nostart-commd ]

       sge_execd controls the Grid Engine Enterprise Edition queues local to the
       machine sge_execd is running on and executes/controls the jobs sent from
       sge_qmaster(8) to be run on these queues.
       Together with sge_execd a sge_commd(8) is brought up automatically on the
       same machine (if not already present).

       Prints  a listing of all options.

   -lj log_file
       Enables job logging. All actions taken by sge_execd from receiving the
       job until returning it to sge_qmaster(8) are logged to the log_file. This
       feature is also available with the sge_qmaster(8) daemon.

       Do not start up sge_commd(8) automatically with sge_execd and evaluate
       the COMMD_HOST environment variable to find the corresponding

       If a load sensor is configured for sge_execd via either the global or the
       execution host specific cluster configuration (see sge_conf(5)) the
       executable path of the load sensor is invoked by sge_execd on a regular
       basis and delivers one or multiple load figures for the execution host
       (e.g.  users currently logged in) or on the complete cluster (e.g. free
       disk space on a network wide scratch file system). The load sensor may be
       a script or a binary executable. In either case its handling of the STDIN
       and STDOUT stream and its control flow must comply to the following

       The load sensor has to be written as infinite loop waiting at a certain
       point for input from STDIN. If the string quit is read from STDIN, the
       load sensor is supposed to exit.  As soon as an end-of-line is read from
       STDIN a load data retrieval cycle is supposed to start. The load sensor
       then performs whatever operation is necessary to compute the desired load
       figures.  At the end of the cycle the load sensor writes the result to
       stdout. The format is as follows:

       ·  A load value report starts with a line containing nothing but the word

       ·  Individual load values are separated by newlines.

       ·  Each load value report consists of three parts separated by colons
          (":") and containing no blanks.

       ·  The first part of a load value information is either the name of the
          host for which load is reported or the special name "global".

       ·  The second part is the symbolic name of the load value as defined in
          the host or global complex list (see complex(5) for details). If a
          load value is reported for which no entry in the host or global
          complex list exists, the reported load value is not used.

       ·  The third part is the measured load value.

       ·  A load value report ends with a line with the word end.

       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_execd 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.

                      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.

       COMMD_HOST     If set, specifies the host on which the particular
                      sge_commd(8) to be used for Grid Engine Enterprise Edition
                      communication of the sge_execd client resides.  Only
                      evaluated if the -nostart-commd option was specified at
                      the sge_execd command-line.  Per default the local host is

       sge_execd usually is started from root on each machine in the Grid Engine
       Enterprise Edition pool.  If started by a normal user, a 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 treated correctly by the
