WebbSummary: The purpose of this PR is to refactor Random Number Generator (RNG) design in ATen. Currently, RNGs in PyTorch has an assymetrical design, i.e. CPU Generators use an ATen class, whereas CUDA Generators use legacy THC code (THCRNGState, THCState, THCRandom_Init etc.). Moreover, the concept of generators in ATen aren't clear from its … Webb14 juni 2024 · So until very recently, PyTorch used two CUDA RNGs the MTGP32 and the Philox 4x32 10. My impression is that what you are getting different state values for the former - I must admit I’m ignorant of the specifics why that is (they’re generated using curandMakeMTGP32KernelState from the cuRAND API). The happy news is that with the …

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. Webb// the philox_4x32_10 algorithm.

The result matches the original row vector x created with the default generator. rng (s) xold = rand (1,5) In addition to Threefry and ARS, Salmon et al. described a third counter-based PRNG, Philox, based on wide multiplies; e.g. multiplying two 32-bit numbers and producing a 64-bit number, or multiplying two 64-bit numbers and producing a 128-bit number. As of 2024, Philox is popular on CPUs and GPUs. On GPUs, nVidia's cuRAND library and TensorFlow provide implementations of Philox. On CPUs, Intel's MKL provides an implementation.
