I want to use multidimensional SharedArray to calculate in parallel.

From the documents (https://docs.julialang.org/en/stable/manual/parallel-computing/), the following code calculates in parallel for 1-dimensional array:

```
a = SharedArray{Float64}(10)
@parallel for i = 1:10
a[i] = i
end
```

How can I do this for 2-dimensional array like the following?

```
# this is not runnable
a = SharedArray{Float64}(10, 5)
@parallel for i = 1:10, j = 1:5
a[i, j] = i + j
end
```
