Webb15 dec. 2024 · The RNG algorithm used by stateless RNGs is device-dependent, meaning the same op running on a different device may produce different outputs. Algorithms … WebbPhilox constructors in kernels take the cuda rng generator's current offset. The Philox constructor then carries out offset/4 (a uint64_t division) to compute its internal offset in its virtual Philox bitstream of 128-bit chunks. In other words, it assumes the incoming offset is a multiple of 4. But (in current code) that's not guaranteed.
