The Rust Rand Book - Parallel RNGs has a very good summary about parallel RNGs. It also gives code examples using the rayon library. However, a few things to notice.

1. rand::ThreadRng (obtained by calling rand::thread_rng) is often used in code examples of parallel RNGs as it uses thread-local storage …

Xoshiro

Xoshiro is a family of fast, space-efficient and high quality PRNGs. It is considered the state-of-the-art (SOTA) family of non-cryptographic pseudo random number generators (PRNGs). The Rust crate rand_xoshiro (which is part of the popular Rust crate rand) has implementations of Xoshiro256Plus and Xoshiro256PlusPlus . Xoshiro256PlusPlus is a very good …

In pratice, the approach of separate RNGs with different seeds for threads/processes is widely used (even though theoretically those RNGs might have overlaping sequences, which is undesirable). For more discussions on this approach, please refer to The Rust Rand Book - Parallel RNGs and Seed Many RNGs in Rust . The …
