示例1: operator
DINLINE void operator()(BoxWriteOnly buffWrite,
uint32_t seed,
float fraction,
Mapping mapper) const
{
/* get position in grid in units of SuperCells from blockID */
const Space block(mapper.getSuperCellIndex(Space(blockIdx)));
/* convert position in unit of cells */
const Space blockCell = block * Mapping::SuperCellSize::toRT();
/* convert CUDA dim3 to DataSpace<DIM3> */
const Space threadIndex(threadIdx);
const uint32_t cellIdx = DataSpaceOperations<DIM2>::map(
mapper.getGridSuperCells() * Mapping::SuperCellSize::toRT(),
blockCell + threadIndex);
/* get uniform random number from seed */
auto rng = nvidia::rng::create(
nvidia::rng::methods::Xor(seed, cellIdx),
nvidia::rng::distributions::Uniform_float());
/* write 1(white) if uniform random number 0<rng<1 is smaller than 'fraction' */
buffWrite(blockCell + threadIndex) = (rng() <= fraction);
