Webb15 okt. 2024 · Hi @t-vi.Thanks for helping in the forum and reporting the bug! I am working on a full refactor of the state of Generators in PyTorch (syed-ahmed@2fd5216) and will be submitting it in the next couple of days.I intend to fix this bug I will include the correct behavior for manual_seed in the new Philox module in my PR and also clear some of the … WebbRNG. It is distinguished from the conventional RNG in that there is no state. Random numbers are generated only using a counter. The Philox 4x32-10 RNG described in the paper has been installed in MATLAB, NVIDIA’s cuRAND, and Intel’s MKL. Philox generates random data with ten rounds of computation. In this paper, we propose a new RNG that ...

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.

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 … WebbC++ (Cpp) _mm512_set1_epi32 - 7 examples found.

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.
