Description

A Philox4x32-10 counter-based pseudorandom number generator [Salmon11].

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);
};

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).
