[MITgcm-support] question about cube-sphere halos

[Alistair Adcroft]

I guess we need to know what interpolation is being done on and for - why do
you have output within the corners and why are interpolating in the halo
regions when the data is on the next tile?

No - there is no correct values of XC or YC in the corner regions - what
value should XC(0,0,bi,bj) have? There are two possible different values.

I didn't know about the CPP flag - I'll see what Chris is trying to do there
but whatever it is it can't be done on the cube ...

Alistair, I notice a flag called EXCH_UPDATE_CORNERS in the exch2 routines.
Benny is only looking to get the values of XC, YC, XG, YG, for interpolation
purposes (as his informative message clearly stated ;-).  These are not
ambiguous and setting them to correct values should not affect rest of code
in any way, right?
