------------------------


The qtask file gives an administrator a means to specify resource requests and
other submit options  for his users individually for each job type. Currently
only qtcsh accesses the .qtask
file. Qsub and qrsh (not in case of qrsh -inherit) should be enhanced in an
analoguous fashion. Open questions are whether an additional submit switch is
needed to allow for explicitly
disabling qtask file consideration.

Or we could just look for .../[.]sge_request.<cmd> and if it exists
use it instead of .../[.]sge_request. In fact, here's a patch that
does just that :-)

A qtask(1) file based job categories could be used to make lack of a means to
request resources separately for master task as outlined in

  http://gridengine.sunsource.net/issues/show_bug.cgi?id=75

less urgent. With a -cat <category> switch one could "cultivate" the workaround
( well, I know this is *evil*) allowing administrators to prepare a qtask(1)
file that maps descriptive job category names into job submit options

   fluent2   -pe mpich 2 -l fluent_paralell=0.5
   fluent4   -pe mpich 4 -l fluent_paralell=0.25
   fluent8   -pe mpich 8 -l fluent_paralell=0.125

an end user then would simply use

   # qsub -cat fluent2 fluent.sh
   # qsub -cat fluent4 fluent.sh
   # qsub -cat fluent8 fluent.sh

further improvements to easen end user job submission could be achieved if
qtask(1)-based job categories would support expressions such as

   fluent   2 -l fluent_paralell={1/$SLOTS}

a fluent job then could be submitted like this

   # qsub -pe mpich 2 -cat fluent
   # qsub -pe mpich 4 -cat fluent
   # qsub -pe mpich 8 -cat fluent

This should be a relatively easy RFE to address.  The functionality is already
built into JAPI to support the DRMAA job category job template attribute.
