qtask - file format of the qtask file.
A qtask file defines which commands are submitted to Sun
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.
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 glo-
bal 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 com-
mands by users.
The principle format of the qtask file is that of a tabu-
lated list. Each line starting with a '#' character is a
comment line. Each line despite comment lines defines a com-
mand to be started remotely.
Definition starts with the command name that must match
exactly the name as typed in a qtcsh(1) command-line. Path-
names 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
An exclamation mark prefixing the command in the cluster
global qtask file prevents overriding by the user supplied
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
sge_intro(1), qtcsh(1), qrsh(1).
