Philox rng

WebbPhilox is a counter-based RNG based which generates values by encrypting an incrementing counter using weak cryptographic primitives. The seed determines the key that is used for the encryption. Unique keys create unique, independent streams. Philox lets you bypass the seeding algorithm to directly set the 128-bit key. WebbPhilox is a 64-bit PRNG that uses a counter-based design based on weaker (and faster) versions of cryptographic functions [1]. Instances using different values of the key …

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. great college advice https://digitalpipeline.net

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 … WebbPhilox is a 64-bit PRNG that uses a counter-based design based on weaker (and faster) versions of cryptographic functions [1].
