DESCRIPTION
       Univa 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 dis-
       tributed 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 paral-
       lel jobs can also be submitted to Univa Grid Engine.


USER INTERFACE
       The Univa 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 Univa Grid Engine execu-
              tion hosts.

       qlogin(1)
              qlogin  initiates  a  telnet or similar login session with auto-
              matic 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.

              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 Univa Grid Engine com-
              parable to the standard Unix facility rsh, to allow for the sub-
              mission of batch jobs which, upon  execution,  support  terminal
              I/O (standard/error output and standard input) and terminal con-
              trol, to provide a batch job  submission  client  which  remains
              active until the job has finished or to allow for the Univa 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 Univa 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  Univa 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 associ-
              ated 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 Univa Grid Engine.
              
        qsub(1)
              qsub is the user interface for submitting a job to Grid
              Engine.
