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 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.
