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.
