[MITgcm-devel] change to ctrl_set_pack_xy for default weighttype

[gael forget]

Like I said, in my opinion, it is a feature that is only 
useful for early development and testing, which you 
don’t really want to use in the long run.

Looks about right at first glance. 

I would use a different name though, to be safer, avoid confusion 
(pkg/ctrl does generate a wunit.data output…) and indicate what
is in the file. Maybe wt_one.data in analogy with the names 
I use in the ocean state estimate, which provides an example @
http://mitgcm.org/viewvc/MITgcm/MITgcm_contrib/gael/verification/global_oce_llc90/input_itXX/data.ctrl?revision=1.7&view=markup

Also it would be better to add indices in lines such 
as xx_gentim2d_weight (1:4)= 'wunit', 'wunit', 'wunit',’wunit'

> (i think) with the appropriate dimensions -- in this case Nx by Ny, as these are 2D controls -- and set uniformly to 1.0, in the run directory. (Note i have ALLOW_NONDIMENSIONAL_CONTROL_IO #define'd in ECCO_CPPOPTIONS.h)
It would be better to put ALLOW_NONDIMENSIONAL_CONTROL_IO
and control related compile options in CTRL_OPTIONS.h

One more thing I should mention : not right now, but sooner rather 
than later, we want to remove custom versions of ctrl_map_ini_genarr.F
that are in verification experiments. This should boil down to adding a 
few lines in pkg/ctrl_map_ini_genarr.F

But let’s wait until after you update your weights/pre-conditioner run 
time settings, before we start looking into those two aspects.
Please give us a heads up when you get there.

Cheers,
Gael
