Reshape DistributedArrays

Specific Domains Julia at Scale
1

From an existing DistributedArrays

dr = DistributedArrays.distribute(rand(2,3,4))

I want to generate a new DistributedArrays which is flattened version of dr with dimensions 3 x 12 by “vcat” out of the following slices:

dr[:,1,:]
dr[:,2,:]
dr[:,3,:]

What will be the most computationally and memory efficient way to achieve this?

Any suggestions? Of course for real problems the array will be much bigger than this?! @andreasnoack?!
