NAME
sge_schedd - Grid Engine job scheduling agent
SYNOPSIS
sge_schedd [ -help ]
DESCRIPTION
sge_schedd computes the scheduling decisions in an Grid
Engine cluster. The information necessary for the decision
is retrieved from sge_qmaster(8) via an event interface.
After applying the scheduling algorithm, sge_schedd communi-
cates the scheduling decision back to sge_qmaster(8) again
via the Grid Engine GDI. In order to trigger an sge_schedd
scheduling run, sge_qmaster(8) samples changes in the clus-
ter status and periodically notifies sge_schedd
By using the -tsm option of the qconf(1) command, sge_schedd
can be forced to print trace messages of its next scheduling
run to the file <sge_root>/<cell>/common/schedd_runlog. The
messages indicate the reasons for jobs and queues not being
selected in that run
OPTIONS
-help
Print version number of the scheduler.
ENVIRONMENTAL VARIABLES
SGE_ROOT Specifies the location of the Grid Engine
standard configuration files.
SGE_CELL If set, specifies the default Grid Engine
cell. To address a Grid Engine cell
sge_schedd 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.
SGE_DEBUG_LEVEL
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.
SGE_QMASTER_PORT
If set, specifies the tcp port on which
sge_qmaster(8) is expected to listen for com-
munication requests. Most installations will
use a services map entry for the service
"sge_qmaster" instead to define that port.
