Parallel Range Algorithms - the Evolution of Parallelism in C++

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.
