[CUDA graphs] [JIT] Capture-safe RNG in nvfuser #50148

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 … 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. 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 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. " - Philox rng
