QTASK(5)                   Grid Engine File Formats                   QTASK(5)

       qtask - file format of the qtask file.

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

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

FFOORRMMAATT
       The principle format of the _q_t_a_s_k file is that  of  a  tabulated  list.
       Each  line  starting  with a '#' character is a comment line. Each line
       despite comment lines defines a command to be started remotely.

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

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

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

EEXXAAMMPPLLEESS
       The following _q_t_a_s_k file

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

       designates the applications netscape, grep and verilog for  interactive
       remote execution through Grid Engine. Netscape 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.
