How do i allocate 2D arrays on the device memory? Example: int **A

2

u can define 2D CUDA arrays readable using texture fetches.

You’d need to do something like this.

of course, if you define a 2D array as a 1D array with a fixed row length, then this is trivial.

4

Don’t do it.

Do 1D arrays instead, its much easier
