API
Syntax
template<std::int32_t VecSize = 1> class philox4x32x10 { public: static constexpr std::uint64_t default_seed = 1; static constexpr std::int32_t vec_size = VecSize; philox4x32x10() : philox4x32x10(default_seed) {} philox4x32x10(std::uint64_t seed, std::uint64_t offset = 0); philox4x32x10(std::initializer_list<std::uint64_t> seed, std::uint64_t offset = 0); philox4x32x10(std::uint64_t seed, std::initializer_list<std::uint64_t> offset); philox4x32x10(std::initializer_list<std::uint64_t> seed, std::initializer_list<std::uint64_t> offset); };

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. |

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). |
