Code inspection: A tile kernel must be launched with a block size of 1

This inspection reports a launch of a __tile_global__ kernel with a block size other than 1. The block size is the second argument of the execution configuration, and for tile kernels it needs to be 1.

Example

                __tile_global__ void tile_kernel(int* data);

                void launch(int* data, int grid)
                {
                    tile_kernel<<<grid, 2>>>(data);
                }
            

                __tile_global__ void tile_kernel(int* data);

                void launch(int* data, int grid)
                {
                    tile_kernel<<<grid, 1>>>(data);
                }
