Philox rng

http://bytemeta.vip/repo/pytorch/pytorch/issues/91950 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.

In regions captured by CUDA graphs, you may only use the default CUDA RNG generator on the device that's current when capture begins. If you need a non-default (user-supplied) generator, or a generator on another device, please file an issue. 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. ching cheng hanji original lyrics

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 …
