Webbrng (seed,generator) also specifies the type of random number generator to use. For example, rng (0,'philox') initializes the Philox 4x32 random generator with a seed of 0. … 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.

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. greenfields primary maidstone

"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 … " - Philox rng
