ugovaretto / work_queue.rs
Created Apr 19, 2022 — forked from NoraCodes/work_queue.rs
An example of a parallel work scheduling system using only the Rust standard library
View work_queue.rs
// Here is an extremely simple version of work scheduling for multiple
// processors.
//
// The Problem:
// We have a lot of numbers that need to be math'ed. Doing this on one
// CPU core is slow. We have 4 CPU cores. We would thus like to use those
// cores to do math, because it will be a little less slow (ideally
// 4 times faster actually).
//
// The Solution:
