Philox 状態で使用するキー。 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.

My impression is that what you are getting different state values for the former - I must admit I’m ignorant of the specifics why that is (they’re generated using curandMakeMTGP32KernelState from the cuRAND API).

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.

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 …
