WebNov 11, 2024 · Assuming that we want to allocate a 2D padded array of Nrows x Ncols floating point (single precision) elements, the syntax for cudaMallocPitch is the following: cudaMallocPitch (&devPtr, &devPitch, Ncols * sizeof (float), Nrows); where devPtr is an output pointer to float ( float *devPtr) pointing to the allocated memory space; cudaMallocPitch (&devPtr, &devPitch, Ncols * sizeof (float), Nrows); where devPtr is an output pointer to float ( float *devPtr ). devPitch is a size_t output variable denoting the length, in bytes, of the padded row. Nrows and Ncols are size_t input variables representing the matrix size.
