sge_intro.1 - a facility for executing UNIX jobs on remote machines
Sun 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 situation of each machine and the resource requirements of the
User level checkpointing programs are supported and a transparent
checkpointing mechanism is provided (see sge_ckpt(1)). 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 Sun Grid Engine.
The Sun Grid Engine user interface consists of several programs which
are described separately.
qacct extracts arbitrary accounting information from the cluster
qalter changes the characteristics of already submitted jobs.
qconf provides the user interface for configuring, modifying,
deleting and querying queues and the cluster configuration.
qdel provides the means for a user/operator/manager to cancel
qhold holds back submitted jobs from execution.
qhost displays status information about Sun Grid Engine
qlogin initiates a telnet or similar login session with
automatic selection of a low loaded and suitable host.
qmake is a replacement for the standard Unix make facility. It
extends make by its ability to distribute independent make steps
across a cluster of suitable machines.
qmod 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 signaled) or to suspend and
enable jobs executing in the owned queues.
qmon provides a Motif command interface to all Sun Grid Engine
functions. The status of all or a private selection of the
configured queues is displayed on-line by changing colors at
corresponding queue icons.
qquota provides a status listing of all currently used resource
quotas (see sge_resource_quota(1).)
qresub creates new jobs by copying currently running or pending
qrls releases holds from jobs previously assigned to them e.g.
via qhold(1) (see above).
qrdel provides the means to cancel advance reservations.
qrsh can be used for various purposes such as providing remote
execution of interactive applications via Sun Grid Engine
comparable to the standard Unix facility rsh, to allow for the
submission of batch jobs which, upon execution, 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 Sun Grid
Engine-controlled remote execution of the tasks of parallel
qrstat provides a status listing of all advance reservations in
qrsub is the user interface for submitting a advance reservation
to Sun Grid Engine.
qselect prints a list of queue names corresponding to specified
selection criteria. The output of qselect is usually fed into
other Sun Grid Engine commands to apply actions on a selected
set of queues.
qsh(1) qsh opens an interactive shell (in an xterm(1)) on a low loaded
host. Any kind of interactive jobs can be run in this shell.
qstat provides a status listing of all jobs and queues
associated with the cluster.
qtcsh is a fully compatible replacement for the widely known and
used Unix C-Shell (csh) derivative tcsh. It provides a command-
shell with the extension of transparently distributing execution
of designated applications to suitable and lightly loaded hosts
via Sun Grid Engine.
qsub is the user interface for submitting a job to Sun Grid
