cudaMallocPitch : pitch size Will the pitch be different for two arrays with same dimension ?

Hi all,

I want to allocate the memory of two arrays (dimension: nrows*ncols) using cudaMallocPitch and I was wondering if I can use a single variable safely for the pitch for both of them. Here is my code below:

float2 *A, *B;

size_t pitch_A, pitch_B ;

cudaMallocPitch((void**) &A, &pitch_A, ncols*sizeof(float2), nrows);

cudaMallocPitch((void**) &B, &pitch_B, ncols*sizeof(float2), nrows);

Is there a chance that pitch_A and pitch_B will be different ?

Thanks in advance.
