NAME

       qtask - file format of the qtask file.

DESCRIPTION

       A  qtask  file defines which commands are submitted to Grid Engine for remote execution by qtcsh(1).  The
       qtask file optionally may contain qrsh(1) command-line parameters. These parameters  are  passed  to  the
       qrsh(1) command being used by qtcsh to submit the commands.

       Both  a  cluster  global  qtask  file  defining  cluster  wide  defaults,  and a user specific qtask file
       eventually overriding and enhancing those definitions, are supported. The cluster global file resides  at
       <sge_root>/<cell/common/qtask, while the user specific file can be found at ~/.qtask. An exclamation mark
       preceding  command  definitions  in  the  cluster  global  file  can be used by the administrator to deny
       overriding of such commands by users.

FORMAT

       The overall format of the qtask file is that of a tabulated list. Each line starting with a '#' character
       is a comment line. Each non-comment line defines a command to be started remotely.

       Definition starts with the command name that must match exactly the name as typed in a qtcsh(1)  command-
       line. Pathnames are not allowed in qtask files. Hence absolute or relative pathnames in qtcsh(1) command-
       lines  always  lead  to  local  execution, even if the command itself is the same as defined in the qtask
       file.

       The command name can be followed by an arbitrary number of qrsh(1) option arguments which are  passed  on
       to qrsh(1) by qtcsh(1).

       An  exclamation  mark  prefixing  the command in the cluster global qtask file prevents overriding by the
       user supplied qtask file.

EXAMPLES

       The following qtask file

              firefox -l a=sol-sparc64 -v DISPLAY=myhost:0
              grep -l h=filesurfer
              verilog -l veri_lic=1

       designates the applications firefox, grep and verilog  for  interactive  remote  execution  through  Grid
       Engine. Firefox is requested to run only on Solaris64 architectures with the DISPLAY environment variable
       set  to 'myhost:0', grep only runs on the host named 'filesurfer', and verilog requests availability of a
       verilog license in order to get executed remotely.
