sge_execd(8) 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 to be run on these queues.



Prints a listing of all options.


If a load sensor is configured for sge_execd via either the global host configuration or the execution-host-specific cluster configuration (See 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:

  • A load value report starts with a line containing only either the word "start" or the word "begin".
  • 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 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 only the word "end".


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 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 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.
