The C++ Zero Cost Conf, dedicated to efficient backend development in C++ and low-level details, will take place on August 2nd. This event is designed for developers seeking to enhance the performance of their systems.

The conference will be held simultaneously in three cities, offering various participation formats:

• Moscow: In-person and online

• Belgrade: In-person and online

• Saint Petersburg: In-person only, with additional activities

What to Expect at the Conference

Experienced engineers from renowned companies will share how they address real-world challenges and achieve "zero-cost abstraction" in their programs. This means they will explain how to write code such that complex components do not impede performance. The conference will feature numerous practical examples and concrete data.

Among the key topics of the presentations are:

• Memory Aliasing: Its impact on performance and the complexities of its maintenance.

• C++20 Modules: Practical implementation of new language features in large-scale projects.

• Hardening: Code protection tools and their evolution.

• The Cost of std::simd Abstraction: Analysis of universal SIMD code behavior on various architectures (x86 and ARM).

• Dependency Management: An examination of working with libraries and tools in CMake, Meson, Conan, vcpkg, and other systems.

• Performance Puzzlers: An expert discussion of unconventional performance challenges with Sergey Slotin.

Practical Workshop and Other Activities

The conference will host a practical workshop on the Perforator tool. This specialized system is utilized by Yandex for continuous performance analysis of its services. Attendees will be guided on how to use it to identify bottlenecks in their programs.

Additionally, participants can engage in an interactive Case Lab session, where teams will attempt to solve a real-world problem related to improving application reliability. Naturally, there will also be C++ code golf — a competitive and enjoyable event where the goal is to write functional code using the fewest possible characters.

Following the main program, an after-party awaits participants, providing an informal setting for networking.
