Dear All,

I have a 3d array `V = zeros(N,N,N)`

and I would like to reverse it with respect to the last component. I achieve this by using the following function. This works well using `CuArray`

(on master, see link) for `A`

but this is very inefficient as `N~100`

. Hence the gpu is wasted doing such a small reverse.

I am wondering if any of you has an idea to speed this up on GPU?

Thank you very much

Best regards

```
function myreverse!(A)
n = size(A)
for jj = 1:n[2], ii = 1:n[1]
reverse!(A[ii,jj,:])
end
end
```
