NAME
Grid Engine - a facility for executing UNIX jobs on remote
machines
DESCRIPTION
Grid Engine is a facility for executing UNIX batch jobs
(shell scripts) on a pool of cooperating workstations. Jobs
are queued and executed remotely on workstations at times
when those workstations would otherwise be idle or only
lightly loaded. The work load is distributed among the
workstations in the cluster corresponding to the load situa-
tion of each machine and the resource requirements of the
jobs.
User level checkpointing programs are supported and a tran-
sparent checkpointing mechanism is provided (see
<B><A HREF="../htmlman1/sge_ckpt.html">sge_ckpt(1)</A></B>). Checkpointing jobs migrate from workstation
to workstation without user intervention on load demand. In
addition to batch jobs, interactive jobs and parallel jobs
can also be submitted to Grid Engine.
USER INTERFACE
The Grid Engine user interface consists of several programs
which are described separately.
<B><A HREF="../htmlman1/qacct.html">qacct(1)</A></B>
<I>qacct</I> extracts arbitrary accounting information from
the cluster logfile.
<B><A HREF="../htmlman1/qalter.html">qalter(1)</A></B>
<I>qalter</I> changes the characteristics of already submitted
jobs.
<B><A HREF="../htmlman1/qconf.html">qconf(1)</A></B>
<I>qconf</I> provides the user interface for configuring,
modifying, deleting and querying queues and the cluster
configuration.
<B><A HREF="../htmlman1/qdel.html">qdel(1)</A></B>
<I>qdel</I> provides the means for a user/operator/manager to
cancel jobs.
<B><A HREF="../htmlman1/qhold.html">qhold(1)</A></B>
<I>qhold</I> holds back submitted jobs from execution.
<B><A HREF="../htmlman1/qhost.html">qhost(1)</A></B>
<I>qhost</I> displays status information about Grid Engine
execution hosts.
<B><A HREF="../htmlman1/qlogin.html">qlogin(1)</A></B>
<I>qlogin</I> initiates a telnet or similar login session with
automatic selection of a low loaded and suitable host.
<B><A HREF="../htmlman1/qmake.html">qmake(1)</A></B>
<I>qmake</I> is a replacement for the standard Unix <I>make</I>
facility. It extends make by its ability to distribute
independent make steps across a cluster of suitable
machines.
<B><A HREF="../htmlman1/qmod.html">qmod(1)</A></B>
<I>qmod</I> allows the owner(s) of a queue to suspend and
enable all queues associated with his machine (all
currently active processes in this queue are also sig-
naled) or to suspend and enable jobs executing in the
owned queues.
<B><A HREF="../htmlman1/qmon.html">qmon(1)</A></B>
<I>qmon</I> provides a Motif command interface to all Grid
Engine functions. The status of all or a private selec-
tion of the configured queues is displayed on-line by
changing colors at corresponding queue icons.
<B><A HREF="../htmlman1/qresub.html">qresub(1)</A></B>
<I>qresub</I> creates new jobs by copying currently running or
pending jobs.
<B><A HREF="../htmlman1/qrls.html">qrls(1)</A></B>
<I>qrls</I> releases holds from jobs previously assigned to
them e.g. via <B><A HREF="../htmlman1/qhold.html">qhold(1)</A></B> (see above).
<B><A HREF="../htmlman1/qrsh.html">qrsh(1)</A></B>
<I>qrsh</I> can be used for various purposes such as providing
remote execution of interactive applications via Grid
Engine comparable to the standard Unix facility rsh, to
allow for the submission of batch jobs which, upon exe-
cution, support terminal I/O (standard/error output and
standard input) and terminal control, to provide a
batch job submission client which remains active until
the job has finished or to allow for the Grid Engine-
controlled remote execution of the tasks of parallel
jobs.
<B><A HREF="../htmlman1/qselect.html">qselect(1)</A></B>
<I>qselect</I> prints a list of queue names corresponding to
specified selection criteria. The output of <I>qselect</I> is
usually fed into other Grid Engine commands to apply
actions on a selected set of queues.
<B><A HREF="../htmlman1/qsh.html">qsh(1)</A></B>
<I>qsh</I> opens an interactive shell (in an <B><A HREF="../htmlman1/xterm.html">xterm(1)</A></B>) on a
low loaded host. Any kind of interactive jobs can be
run in this shell.
<B><A HREF="../htmlman1/qstat.html">qstat(1)</A></B>
<I>qstat</I> provides a status listing of all jobs and queues
associated with the cluster.
<B><A HREF="../htmlman1/qtcsh.html">qtcsh(1)</A></B>
<I>qtcsh</I> is a fully compatible replacement for the widely
known and used Unix C-Shell (<I>csh</I>) derivative <I>tcsh</I>. It
provides a command-shell with the extension of tran-
sparently distributing execution of designated applica-
tions to suitable and lightly loaded hosts via Grid
Engine.
<B><A HREF="../htmlman1/qsub.html">qsub(1)</A></B>
<I>qsub</I> is the user interface for submitting a job to Grid
Engine.
