Ruslan is one of the authors of the C++ proposal that aims to introduce **Parallel Range Algorithms**, bringing together the power of **C++ Ranges** and **parallel execution**. This talk explores how these new algorithms improve **code clarity, expressiveness, and performance**.

We’ll consider the following key aspects:

* What **Parallel Range Algorithms** are, and how they differ from **C++17 parallel algorithms** and **serial range algorithms**;
* What **design choices** were made, specifically addressing **bounded ranges** and **range-as-the-output**, and some corner cases;
* The **performance implications** of Parallel Range Algorithms;
* The **safety implications** of Parallel Range Algorithms;
* How these algorithms apply to **heterogeneous computing** based on **oneAPI DPC++ library** (oneDPL) experience.

This talk is based on an active **C++ standard proposal (P3179)** that has strong potential to land in **C++26**. We will break down **key design decisions**, explore **code examples**, and discuss how these algorithms enable more expressive and scalable parallelism in modern C++.
While this session will be **technical**, it is targeted to be accessible to **different audiences**, from library authors to everyday C++ developers. Expect **technical insights, and a look into the future of parallel programming in C++**.

There is a discord for the meetup that you can join https://discord.gg/98T5XPWcrA to help foster remote interaction!
We always plan to go to the Burns pub for social hour after the presentation.

This month food will be supplied by Alteryx. Please answer the question so we know how many people are attending in person, and if you have any dietary needs.

Thank you to our sponsors:

* Trimble for event space and soft drinks
