Benchmarking C++ Code

Log in to save this to your schedule and see who's attending!

With the ending of Moore's Law and the rise of multicore systems, programmers from across the industry are increasing forced to develop and maintain highly performance sensitive software. For C++, a language frequently used for performance sensitive projects, benchmarking and performance analysis is especially important. Developing good benchmarks can be tricky; gathering and analyzing data from benchmarks can be an even greater challenge.

This talk will discuss techniques and best practices for writing C++ benchmarks using facilities from the standard library and Boost. We'll also cover the development of performance unit/regression tests. We'll discuss the statistical best practices for gathering data, as well as techniques for benchmarking a variety of different metrics - time, memory, algorithmic complexity, etc.

The main topics which will be covered:

* Statistical Best Practices (dealing with uncertainty, achieving statistical confidence, how to sample)
* Time-Based Benchmarking (best practices for timing, derived time-based metrics)
* Non-Time-Based Benchmarking (memory, algorithmic complexity in time and space, etc)
* Techniques for C++-specific Performance Metrics (counting copies/moves, allocator tricks)
* Converting Benchmarks into Tests
