Grid-Stride loops for 2D grid of 1D blocks implementation

Accelerated Computing CUDA CUDA Programming and Performance
#1

Hi,

In the case of 1D Grid of 1D blocks, the grid-stride loops is implemented as follows:

for (int i = blockIdx.x * blockDim.x + threadIdx.x; i < n; i += blockDim.x * gridDim.x)

But, how is it implemented for 2D grid of 1d blocks?

Thanks
