Zero-Overhead Abstractions: Building Flexible Vector Math Libraries with C++20 Concepts and Customization Points - Greg von Winckel - CppCon 2025
---
This talk demonstrates how C++20's Concepts and Customization Point Objects (CPOs) provide a flexible, opt-in approach to vector algorithms—a compelling alternative to inheritance-based interfaces. Starting with foundational concepts and CPOs, we'll design mathematical abstractions that enable precise compile-time requirements with helpful diagnostics and clear error messages.
Through a practical vector framework implementation, we'll explore patterns essential for high-performance scientific computing applications, including interpolation and iterative methods for linear and nonlinear systems. Attendees will learn how CPOs with intelligent fallbacks parallel the familiar base-class/override structure of OOP, providing similar code reuse and customization opportunities without inheritance entanglements, while enabling seamless interoperability between diverse container types in the spirit of the STL.
As a C++ developer and architect at Sandia National Laboratories for the past decade, I've witnessed the burden of OOP overuse: complicated class hierarchies, parallelism compatibility issues, and testing challenges. The Real Vector Framework I've developed demonstrates how static polymorphism and free functions provide cleaner, more flexible alternatives to inheritance—bringing modern C++ practices to scientific computing while preserving the performance critical to our applications.

CppCon is the annual, week-long face-to-face gathering for the entire C++ community. The conference is organized by the C++ community for the community. You will enjoy inspirational talks and a friendly atmosphere designed to help attendees learn from each other, meet interesting people, and generally have a stimulating experience. Taking place this year in Aurora, Colorado, near the Denver airport, and including multiple diverse tracks, the conference will appeal to anyone from C++ novices to experts.
