Template Parameters
Name | Type | Description |
|---|---|---|
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 single random number is returned by the oneapi::mkl::rng::device::generate function. |
Constructors Input Parameters
Name | Type | Description |
|---|---|---|
seed | std::uint64_t std::initializer_list<std::uint64_t> | Initial conditions of the engine state. |
offset | std::uint64_t std::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). |
