This is especially useful for <strong>CPU-bound tasks</strong> where raw computing power is the bottleneck.</p> <p>In Julia, multithreading is enabled with the environment variable JULIA_NUM_THREADS, and used via macros like Threads.@threads and Threads.@spawn.</p> <p>The goal is to split work into smaller, independent parts that can be safely computed in parallel.</p> <p>We&rsquo;ll also talk about asynchronous programming, which defines coroutines running at the same time on a single thread, and able to yield control to each other while they wait for something.</p> <h4 id="downloadable-content">Downloadable content</h4> <p>Notebook: <a href="https://lemieux.iric.ca/downloads/workshop-25-08-08/multithreading_workshop.jl">julia</a> | <a href="https://lemieux.iric.ca/downloads/workshop-25-08-08/multithreading_workshop.pdf">pdf</a> | <a href="https://lemieux.iric.ca/downloads/workshop-25-08-08/multithreading_workshop.html">html</a></p>
