VecSize |
std::int32_t |
Describes the size of vector which will be produced by generate function by this engine. VecSize values may be 1, 2, 3, 4, 8, 16 as sycl::vec class size. By default VecSize = 1, for this case, a single random number is returned by the oneapi::mkl::rng::device::generate function. |

std::uint32_tstd::initializer_list<std::uint32_t> |
Initial conditions of the engine state. |
offset |
std::uint64_tstd::initializer_list<std::uint64_t> |
number of skipped elements, for initializer_list offset is calculated as: num_to_skip [0]+ num_to_skip [1]*264 + num_to_skip [2]* 2128 + … + num_to_skip [n-1]*264 *(n-1). |
