pcg64

Defined in the <cuda/random> header.

cuda::pcg64 is a 128-bit state PCG XSL RR 128/64 engine that produces 64-bit unsigned integer outputs. It has a period of 2^128 and supports logarithmic-time discard. cuda::pcg64 models the UniformRandomBitGenerator named requirement.

Example

#include <cuda/random>

__global__ void sample_kernel() {
    cuda::pcg64 rng(42);
    auto value = rng();
    rng.discard(10);
}
