Understanding Allocator Impact on Runtime Performance in C++

Explore the challenges and methodologies involved in analyzing the performance impact of local memory allocators in C++ during this conference talk from CppCon 2022. Delve into the process of selecting appropriate tools, overcoming instrumentation and profiling limitations, and designing effective visualizations to present performance comparisons. Gain insights from Parsa Amini's experience in high-performance computing as he discusses the complexities of abstracting performance metrics while minimizing unrelated factors. Learn how to construct compelling cases that explain the impact of design choices on runtime performance, particularly in the context of C++ applications and parallel programming.
