Output constructor does not work with sliced fields

Open jagoosw opened this issue 2 years ago • 11 comments

Hi all,

I've come across a problem a few times with the output writer where it can't set up running with indicesspecified. This presents as a bounds error coming from the offset_data function: https://github.com/CliMA/Oceananigans.jl/blob/c73ef035702b33b8d11c505365a4dd48444444a7/src/Grids/new_data.jl#L33-L48

An example of this occurs when you try to run the "near_global_lat_lon" example when it tries to output surface values: https://github.com/CliMA/Oceananigans.jl/blob/c73ef035702b33b8d11c505365a4dd48444444a7/validation/near_global_lat_lon/near_global_quarter_degree.jl#L296-L301

Essentially what I think is happening is that when we output data and specify some slice that isn't the dimensions of the grid, in this example just the surface level grid.Nz, the data is being correctly (? not sure we actually want the halo here) selected as e.g. -Hx:Nx+Hx in dimensions specified as : but just whatever indices specified by the user in the other dimensions. In the offset_data function I think ii gets the halo added in all dimensions so there's a miss match.

I'm not sure how to fix this cleanly?

If I try to just output the whole of the fields in the lat lon example then it fails to be able to output the free surface displacement with the same issue.

That was the main issue we discussed in #2740 with locating the free surface at grid.Nz+1.

(from #2740)

Well the issue is that if we want to save the output at the surface (:, :, grid.Nz) we cannot include the free surface if this is defined at grid.Nz+1 (it would not exist at grid.Nz). ...

grid.Nz+1 won against grid.Nz so, for the moment, you should define two different OutptWriters, one for grid-sized variables and one for the free surface.

If I try to just output the whole of the fields in the lat lon example then it fails to be able to output the free surface displacement with the same issue.

This is a bug though. With indices=(:, :, :) we should be able to output any field

The issue here seems to be with parent_index_range. This should return the parent indices which are then used to view(parent(data), parent_indices...). This will not work with sliced fields because in sliced fields the data has windowed indices (returned by parent_index_range), but the parent has indices that always start from 1.

for example for a 10x10x10 grid:

julia> η.data
16×16×1 OffsetArray(::Array{Float64, 3}, -2:13, -2:13, 11:11) with eltype Float64 with indices -2:13×-2:13×11:11:
.
.
.

julia> η.data.parent
16×16×1 Array{Float64, 3}:
.
.
.

So if I try to do view(, :, : grid.Nz+1) it returns

julia> view(η, :, :, grid.Nz+1)
ERROR: BoundsError: attempt to access 16×16×1 Array{Float64, 3} at index [1:16, 1:16, 14:14]

because

julia> parent_indices = parent_index_range.(indices(η), location(η), topology(η.grid), halo_size(η.grid))
(Colon(), Colon(), 14:14)

julia> windowed_parent = view(parent(data), parent_indices...)
ERROR: BoundsError: attempt to access 16×16×1 Array{Float64, 3} at index [1:16, 1:16, 14:14]

In my opinion parent_index_range should return here (Colon(), Colon(), 1:1), but I would like to be sure before breaking everything

Also just to clarify, while output writers accept an argument indices which is then interpreted as applying globally to all outputs, it is also possible to set the indices of each output individually.

I'm not sure I grasp the issue. @jagoosw it might help if you include a simple example (eg some code, and the error that gets produced) that illustrates the issue.

With indices=(:, :, :) we should be able to output any field

I agree with this. Is the problem associated with trying to "remove halos" from output? Does it go away when we write with_halos=true?

In addition to problems with parent_index_range, it looks like there is potentially a problem with the user API (in addition to other bugs). The indices keyword in the output writers is a useful convenience but doesn't generalize well to being able to slice both 3D and reduced or sliced fields.

Here's what we have:

  • All Fields have indices. We can define fields that are essentialy views into other fields, but "sliced" at particular indices. We can also define abstract operations that slice a portion of the domain.
  • We have output writers that can compute and output sliced fields.
  • We have an indices kwarg for output writers that automagically will slice every output along the provided indices. This is convenient, but fails to cover the case that we want to slice all 3D fields, but leave fields that are already sliced untouched.

A few solutions:

  • Throw a BoundsError when we attempt to "re-slice" a field in a way that's invalid. For example, we cannot slice a field with k=Nz+1 at the index k=Nz. This is how Base julia works:
julia> a = rand(2, 3)
2×3 Matrix{Float64}:
 0.493349  0.161279   0.244427
 0.288415  0.0111998  0.543645

julia> b = view(a, :, 4:4)
ERROR: BoundsError: attempt to access 2×3 Matrix{Float64} at index [1:2, 4:4]

  • Add new features that help us build output in a sensible way. One idea is a macro that looks something like
us, vs, ws, Ts = @indices (:, :, Nz) u v w T

This would be equivalent to writing something like

us = Field(u, indices=(:, :, Nz))
vs = Field(v, indices=(:, :, Nz))
ws = Field(w, indices=(:, :, Nz))
Ts = Field(T, indices=(:, :, Nz))

Then, if users want to output surface fields and the free surface, they should use this method rather than the indices kwarg.

Here's an example:

using Oceananigans
grid = RectilinearGrid(arch, size=(20, 20, 20), extent=(1, 1, 1))
a_field = Oceananigans.Fields.Field{Center, Center, Center}(grid; indices=(:, :, 1:1))
model = NonhydrostaticModel(grid = grid, auxiliary_fields=(;a_field))
simulation = Simulation(model, Δt=1.0, stop_iteration=1)

simulation.output_writers[:a_field] = JLD2OutputWriter(model, (model.auxiliary_fields), filename="example.jld2", schedule=IterationInterval(1))

And the error I get:

The problem is these lines

https://github.com/CliMA/Oceananigans.jl/blob/b288527ccf34fc17ec4b31a1e9da7bd8b8d25a10/src/Fields/field.jl#L243-L244

julia> parent_indices = parent_index_range.(indices(a_field), location(a_field), topology(grid), halo_size(grid))
(Colon(), Colon(), 4:4)

julia> windowed_parent = view(parent(a_field.data), parent_indices...)
ERROR: BoundsError: attempt to access 26×26×1 Array{Float64, 3} at index [1:26, 1:26, 4:4]

parent(a_field.data) has a z-index that never reahes 4. The actual offset data has indices 4:4 in the z-direction, but the parent only 1:1. We can view a_field.data at 4:4 not parent(a_field.data) (or in your case even worst 4:23). I think the parent index of a sliced field should be

parent_index_range(index::UnitRange, loc, topo, halo) = 1:(last(index) - first(index) + 1)

(if we assume index::UnitRange means it is a sliced field so it does not have halos)

This is not the whole story though, since the output writer is trying to view the underlying data at [4:23, 4:23, 4:23]. So once we have fixed this we have to deal with the output writers which rely on view(field, indices...). I guess the error here will be somewhere in this function

https://github.com/CliMA/Oceananigans.jl/blob/b288527ccf34fc17ec4b31a1e9da7bd8b8d25a10/src/OutputWriters/output_construction.jl#L50-L60

Here we have to interpolate the indices which result from line 56 with indices(output) that contain the indices of the (maybe) sliced field

Ok! To summarize, we currently have

https://github.com/CliMA/Oceananigans.jl/blob/b288527ccf34fc17ec4b31a1e9da7bd8b8d25a10/src/Grids/grid_utils.jl#L213

which you propose to change to

parent_index_range(index::UnitRange, loc, topo, halo) = 1:(last(index) - first(index) + 1)

I definitely agree that the parent index range of a field with indices 4:4 is 1:1 and your code seems correct to me. This is a clear bug --- should we add this to the indices tests? (I'm not sure what the state of the tests is for indices, but this is an obvious gap.)

Note that with this change, none of the methods for parent_index_range will use the argument halo. So that should be removed. (I think loc and topo are needed to support slicing into "ensemble grids" that have a flat direction with more than one grid point... I think.)

since the output writer is trying to view the underlying data at [4:23, 4:23, 4:23]

I think @navidcy discovered a problem with validate_indices that may be related. But restrict_to_interior may also be broken for sliced fields.

Is this still an issue?

Is this still an issue?

I've just come across this again so I think so yes. Might try and fix soon
