NAME
sge_schedd - Grid Engine job scheduling agent
SYNOPSIS
sge_schedd [ -help ]
DESCRIPTION
<I>sge</I>_<I>schedd</I> computes the scheduling decisions in an Grid
Engine cluster. The information necessary for the decision
is retrieved from <B><A HREF="../htmlman8/sge_qmaster.html">sge_qmaster(8)</A></B> via an event interface.
After applying the scheduling algorithm, <I>sge</I>_<I>schedd</I> communi-
cates the scheduling decision back to <B><A HREF="../htmlman8/sge_qmaster.html">sge_qmaster(8)</A></B> again
via the Grid Engine GDI. In order to trigger an <I>sge</I>_<I>schedd</I>
scheduling run, <B><A HREF="../htmlman8/sge_qmaster.html">sge_qmaster(8)</A></B> samples changes in the clus-
ter status and periodically notifies <I>sge</I>_<I>schedd</I>
By using the -<I>tsm</I> option of the <B><A HREF="../htmlman1/qconf.html">qconf(1)</A></B> command, <I>sge</I>_<I>schedd</I>
can be forced to print trace messages of its next scheduling
run to the file <<I>sge</I>_<I>root</I>>/<<I>cell</I>>/<I>common</I>/<I>schedd</I>_<I>runlog</I>. 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
<I>sge</I>_<I>schedd</I> 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
<B><A HREF="../htmlman8/sge_qmaster.html">sge_qmaster(8)</A></B> 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.
