NAME

       sge_intro.1 - a facility for executing UNIX jobs on remote machines

DESCRIPTION

       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
       jobs.

       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.

USER INTERFACE

       The Sun Grid Engine user interface consists of several programs which are described separately.

       qacct(1)
              qacct extracts arbitrary accounting information from the cluster logfile.

       qalter(1)
              qalter changes the characteristics of already submitted jobs.

       qconf(1)
              qconf provides the user interface for configuring, modifying, deleting and querying queues and the
              cluster configuration.

       qdel(1)
              qdel provides the means for a user/operator/manager to cancel jobs.

       qhold(1)
              qhold holds back submitted jobs from execution.

       qhost(1)
              qhost displays status information about Sun Grid Engine execution hosts.

       qlogin(1)
              qlogin  initiates  a  telnet or similar login session with automatic selection of a low loaded and
              suitable host.

       qmake(1)
              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(1)
              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(1)
              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(1)
              qquota    provides   a   status   listing   of   all   currently   used   resource   quotas   (see
              sge_resource_quota(1).)

       qresub(1)
              qresub creates new jobs by copying currently running or pending jobs.

       qrls(1)
              qrls releases holds from jobs previously assigned to them e.g. via qhold(1) (see above).

       qrdel(1)
              qrdel provides the means to cancel advance reservations.

       qrsh(1)
              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 jobs.

       qrstat(1)
              qrstat provides a status listing of all advance reservations in the cluster.

       qrsub(1)
              qrsub is the user interface for submitting a advance reservation to Sun Grid Engine.

       qselect(1)
              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(1)
              qstat provides a status listing of all jobs and queues associated with the cluster.

       qtcsh(1)
              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(1)
              qsub is the user interface for submitting a job to Sun Grid Engine.
