sge_intro - Grid Engine, a facility for executing jobs on remote
Grid Engine is a facility for executing Unix-like batch jobs (shell
scripts or binaries) on a pool of cooperating CPUs. Jobs are queued and
executed remotely according to defined policies. The CPUs may be in
desktop systems, with jobs run on them at times when they would
otherwise be idle or only lightly loaded. The work load may be
distributed according to the (generalized) load situation of each
machine and the resource requirements of the jobs.
User level checkpointing programs are supported and a transparent
checkpointing mechanism is provided (see sge_ckpt(5)). Checkpointing
jobs migrate from system to system without user intervention on load
demand. In addition to simple batch jobs, interactive jobs and parallel
jobs can also be submitted to Grid Engine.
The Grid Engine user interface consists of several programs which are
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
qevent provides a means of watching Grid Engine events and
acting on jobs finishing.
qhold holds back submitted jobs from execution.
qhost displays status information about Grid Engine execution
qlogin initiates a telnet or similar login session with
automatic selection of a suitable host.
qmake is a replacement for the standard Unix make facility. It
extends make with an ability to distribute independent make
steps across a cluster of suitable machines.
qmod allows the owner(s) of a queue to suspend and enable
queues, e.g. 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 queues.
qmon provides a Motif command interface to all 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.
qping can be used to check the status of Grid Engine daemons.
qquota provides a status listing of all currently used resource
quotas (see sge_resource_quota(5)).
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 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 Grid Engine-
controlled remote execution of the tasks of parallel jobs.
qrstat provides a status listing of all advance reservations in
qrsub is the user interface for submitting an advance
reservation to Grid Engine.
qselect prints a list of queue names corresponding to specified
selection criteria. The output of qselect is usually fed into
other Grid Engine commands to apply actions on a selected set of
qsh(1) qsh opens an interactive shell (in an xterm(1)) on a low loaded
host. Any kind of interactive job 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 Grid Engine.
qsub is the user interface for submitting a job to Grid Engine.
