mcg59¶
The 59-bit multiplicative congruential pseudorandom number generator.
Description
The mcg59 engine is a 59-bit multiplicative congruential generator from NAG Numerical Libraries NAG. The mcg59 generator belongs to linear congruential generators with the period length of approximately \(2^{57}\).
Generation algorithm
\(x_n=ax_{n-1}(mod \ m)\)
\(u_n = x_n / m\)
\(a = 13^{13}, m=2^{59}\)

mcg59::mcg59(sycl::queue queue, std::uint64_t seed = default_seed)
Input Parameters
- queue
Valid
sycl::queueobject, calls of the oneapi::mkl::rng::generate() routine submits kernels in this queue to obtain random numbers from a given engine.- seed
The initial conditions of the generator state, assume \(x_0 = seed \ mod \ 2^{59}\), if \(x_0 = 0\), assume \(x_0 = 1\).
mcg59::mcg59(const mcg59& other)
Input Parameters
- other
Valid
mcg59object. Thequeueand state of the other engine is copied and applied to the current engine.
mcg59::mcg59(mcg59&& other)
Input Parameters
- other
Valid
mcg59object. Thequeueand state of the other engine is moved to the current engine.
mcg59::mcg59& operator=(const mcg59& other)
Input Parameters
- other
Valid
mcg59object. Thequeueand state of the other engine is copied and applied to the current engine.
mcg59::mcg59& operator=(mcg59&& other)
Input Parameters
- other
Valid
mcg59r-value object. Thequeueand state of the other engine is moved to the current engine.
