sge_execd — Sun Grid Engine job execution agent


sge_execd [ -help ]


sge_execd controls the Sun Grid Engine queues local to the machine on which sge_execd is running and executes/controls the jobs sent from sge_qmaster(8) to be run on these queues.



Prints a listing of all options.

Load Sensors

If a load sensor is configured for sge_execd via either the global host configuration 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 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 streams and its control flow must comply to the following rules:

The load sensor must be written as an infinite loop waiting at a certain point for input from STDIN. If the string "quit" is read from STDIN, the load sensor should exit.  When an end-of-line is read from STDIN, a load data retrieval cycle should 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:

Environmental Variables


Specifies the location of the Sun Grid Engine standard configuration files.


If set, specifies the default Sun Grid Engine cell. To address a Sun Grid Engine 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.


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


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


sge_execd usually is started from root on each machine in the Sun Grid Engine 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 handled correctly by the system.


sgepasswd  contains  a  list  of  user  names   and   their corresponding encrypted passwords. If available, the password  file  will  be   used   by  sge_execd. To change the contents  of this file please use the sgepasswd command. It is not advised to  change   that file manually.
