I’m trying to distribute this Array into 2 processes each should have 5 lines I mean from `zeros(10,10,10)` each should have `zeros(5,5,10)` can someone help? I need it to be distributed in Rows and not in Colon, please

```julia
y=zeros(10,10,10)
distribute(y; dist=(2,1,100))
 

Im getting this error ==>error BoundsError: attempt to access 2-element Array{Int64,1} at index [1:200]

```

This doesn’t seem like a valid distribution. You start with `zeros(10,10,10)` that has 1000 elements, and end up with 2 arrays `zeros(5,5,10)` that have 250 elements each? You have lost half your array.

Perhaps you want two arrays of size `(5,10,10)` on each processor? You can do it like this:

```julia
julia> y = zeros(10,10,10);

julia> yd = distribute(y; dist=(2,1,1));

julia> @fetchfrom 2 DistributedArrays.localindices(yd)
(1:5, 1:10, 1:10)

julia> @fetchfrom 3 DistributedArrays.localindices(yd)
(6:10, 1:10, 1:10)

```
