Lightning Talk: Understanding Data Dependency Chains - Makar Kuznietsov - CppCon 2025
---
Long dependency chains in your code might completely nuke the performance. Even on the high-end systems there will be a significant slow-down, as the more threads or more cache will not improve performance in this case. To find a solution it is crucial to be able to differentiate between primary and secondary dependency chains, see what data is the dependency over, and know whether to focus on latency or throughput of instructions. In this talk I will introduce a mental framework to quickly spot and fix long dependency chains, and characterize them with specific quantifiable metrics.

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.
