cudamallocarray - dimensionality

Accelerated Computing CUDA CUDA Programming and Performance

Hi forum,

Please check the following snippet:

void setupTexture(int x, int y)
{
    // Wrap mode appears to be the new default
    texref.filterMode = cudaFilterModeLinear;
    cudaChannelFormatDesc desc = cudaCreateChannelDesc<float2>();

    cudaMallocArray(&array, &desc, y, x);
    cutilCheckMsg("cudaMalloc failed");
}

An array is created. Is it a 1D array or 2D array or linearized 2D array ?

Regards
Sajjad
