It is suggested that you avoid using Excel files (or other spreadsheet tools) for storing data. Parquet file is currently the best format for storing table-like data. If you do want to interact and manipulate your data using Excel (or other spreadsheet tools), dump your data into CSV files and …
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.
rand::ThreadRng (obtained by calling rand::thread_rng) is often used in code examples of parallel RNGs as it uses thread-local storage …

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 …
There are different ways to seed many RNGs (for parallel RNGs).
Below summarizes 3 popular ways.
Seeding RNGs using
std::collections::hash_map::RandomState
or rand::thread_rng
is preferred.
use std::time::{SystemTime, UNIX_EPOCH};
use rand::SmallRng;
fn main () {
let seed = SystemTime::now()
.duration_since(UNIX_EPOCH)
.unwrap()
.as_nanos …
