dogbone composite nesting: contact()%Kdg in nesting.f90 not assigned?

#1 Unread post by blaupole »

Hi,

I'm trying to run the dogbone composite test case.
It errors after reading initial state conditions, which seems to be caused by the k index of the donor grid not containing a sensible value.

It must be a problem at my end since dogbone seems to run successfully for many others.

OS Ubuntu 18.04
gfortran, gcc version 7.5.0
netCDF-Fortran 4.4.4
mpirun (Open MPI) 2.1.1
ROMS checkout April 1 2021, SVN Revision : 1053

The tile configuration for this test run in roms_dogbone_composite.in

Code: Select all

      NtileI == 1  1                             ! I-direction partition
      NtileJ == 2  2                             ! J-direction partition
To obtain more information I have run it in debug mode.

Code: Select all

mpirun -np 2 romsG roms_dogbone_composite.in
One (possibly related?) thing that seems not straightforward to me - the two grids are subdivided into 2 tiles each. In theory shouldn't that become 4 MPI ranks? ROMS won't allow me to assign 4 CPUs to the problem, it only accepts 2.

However, running it with 2 CPU it creates the following error message (full log attached as .txt file)

Code: Select all

As a first question where and how is contact(cr)%Kdg populated ? I see it being allocated in mod_nesting.f90 and I see its syblings Idg and Jdg being populated in set_contact.f90 but can't figure out where Kdg comes from.

Any suggestions would be much appreciated.

Re: dogbone composite nesting: contact()%Kdg in nesting.f90 not assigned?

#2 Unread post by jcwarner »

i think there is a issue with the updated calls for z_weights. There is a check in set_contact that has

IF (.not.ANY(Lcoincident).and.ANY(Lcomposite)) THEN
get_Vweights=.TRUE.
ELSE
get_Vweights=.FALSE.
END IF

i think we need this to allow get_vweights to be true.
then at top of nesting we have

IF ((isection.eq.nzwgt).and.get_Vweights) THEN
DO tile=last_tile(ng),first_tile(ng),-1
CALL z_weights (ng, model, tile)

then in z_weights, it sets the kdg stuff that is missing.
let me dig in a bit and ask Hernan on this one.

Yes, in set_contat.F we need to have instead:

Code: Select all

!
!  Set the switch to compute vertical interpolation weights. Currently,
!  they are only needed in non-coincident composite grids.
!
      IF (.not.ANY(Lcoincident).or.ANY(Lcomposite)) THEN
        get_Vweights=.TRUE.
      ELSE
        get_Vweights=.FALSE.
      END IF
we need .or. instead of .and. in the IF-directive. After I made that change, the dogbone test case runs fine. Thank you to bringing this issue to our attention.
