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

NAME

       qtask - file format of the qtask file.

DESCRIPTION

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

       A cluster global qtask file defining cluster wide defaults and a user specific qtask file eventually overriding and enhancing those defini-
       tions  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 can be used by the administrator to  deny  overriding	of
       such commands by users.

FORMAT

       The  principle  format  of the qtask 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 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 commands itself are
       the same as defined in the qtask files.

       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

	      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 Sun 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.
