philox4x32x10

Implementation of the Philox4x32-10 engine: a counter-based pseudorandom number generator (PRNG) that uses 4x32-bit keys and performs 10 rounds of mixing to produce high-quality randomness.

Subsequence selection methods support

skipAhead (nskip)

Supported

leapfrog (threadIdx, nThreads)

Supported

Batch Processing

Philox4x32x10 engine needs the initial condition (seed) for state initialization. The seed can be either an integer scalar or a vector of \(p\) integer elements, the inputs to the respective engine constructors.

Algorithm Parameters

Philox4x32x10 engine has the following parameters:

Algorithm Parameters for mcg58 engine (Batch Processing)

Parameter	Default Value	Description
algorithmFPType	float	The floating-point type that the algorithm uses for intermediate computations. Can be float or double.
method	defaultDense	Performance-oriented computation method; the only method supported by the algorithm.
seed	\(777\) for a scalar seed NA for a vector seed	Initial condition for state initialization, scalar or vector: Scalar, value of size_t type Vector, pointer to HomogenNumericTable of size \(1 \times p\)
