9 sge_execd [ -help ]
10
12 sge_execd controls the Grid Engine queues local to the machine on which
13 sge_execd is running and executes/controls the jobs sent from sge_qmas‐
14 ter(8) to be run on these queues.

21 If a load sensor is configured for sge_execd via either the global host
22 configuration or the execution-host-specific cluster configuration (See
23 sge_conf(5).), the executable path of the load sensor is invoked by
24 sge_execd on a regular basis and delivers one or multiple load figures
25 for the execution host (e.g. users currently logged in) or the com‐
26 plete cluster (e.g. free disk space on a network wide scratch file sys‐
27 tem). The load sensor may be a script or a binary executable. In either
28 case its handling of the STDIN and STDOUT streams and its control flow
29 must comply to the following rules:
30 The load sensor must be written as an infinite loop waiting at a cer‐
32 tain point for input from STDIN. If the string "quit" is read from
33 STDIN, the load sensor should exit. When an end-of-line is read from
34 STDIN, a load data retrieval cycle should start. The load sensor then
35 performs whatever operation is necessary to compute the desired load
36 figures. At the end of the cycle the load sensor writes the result to
37 stdout. The format is as follows:
38 · A load value report starts with a line containing only the word
40 "start".
41 · Individual load values are separated by newlines.
43 · Each load value report consists of three parts separated by colons
45 (":") and containing no blanks.
46 · The first part of a load value information is either the name of the
48 host for which load is reported or the special name "global".
49 · The second part is the symbolic name of the load value as defined in
51 the host or global complex list (see complex(5) for details). If a
52 load value is reported for which no entry in the host or global com‐
53 plex list exists, the reported load value is not used.
54 · The third part is the measured load value.
56 · A load value report ends with a line with only the word "end".

60 SGE_ROOT Specifies the location of the Grid Engine standard con‐
61 figuration files.
62 SGE_CELL If set, specifies the default Grid Engine cell. To
64 address a Grid Engine cell sge_execd uses (in the order
65 of precedence):
66 The name of the cell specified in the environment
68 variable SGE_CELL, if it is set.
69 The name of the default cell, i.e. default.
71 SGE_DEBUG_LEVEL
74 If set, specifies that debug information should be writ‐
75 ten to stderr. In addition the level of detail in which
76 debug information is generated is defined.
77 SGE_QMASTER_PORT
79 If set, specifies the tcp port on which sge_qmaster(8)
80 is expected to listen for communication requests. Most
81 installations will use a services map entry for the ser‐
82 vice "sge_qmaster" instead to define that port.
83 SGE_EXECD_PORT If set, specifies the tcp port on which sge_execd(8) is
85 expected to listen for communication requests. Most
86 installations will use a services map entry for the ser‐
87 vice "sge_execd" instead to define that port.
88
90 sge_execd usually is started from root on each machine in the Grid
91 Engine pool. If started by a normal user, a spool directory must be
92 used to which the user has read/write access. In this case only jobs
93 being submitted by that same user are handled correctly by the system.
94
96 sgepasswd contains a list of user names and their correspond‐
97 ing encrypted Windows passwords. If available, the password file will
98 be used by sge_execd. To change the contents of this file please
99 use the sgepasswd command. It is not advised to change that file manu‐
100 ally.
