Скачать или смотреть 'Benchmarking in C++' - Nikos Athanasiou [ ACCU 2016 ]

A commonplace among talks on benchmarking is the assumption that a stopwatch - a time measuring mechanism already exists. While this may seem a mundane endeavour it is of great importance to have a reliable, cross platform, easy to use framework for performing "benchmarking experiments".

In this talk we’ll walk through the proper use of chrono to create such a framework, having the following features:

Parametrizable time and clock type per benchmark.

Multiple experiments can run on the same benchmark - hence we can group and compare results as we wish.

User adjustable sampling size - number of times each experiment will run.

Auto detectable sampling- number of times the experiment has to run until we "trust" its results

Benchmarks printable and serializable in a “Python friendly” form.

A Python script to read the output of a serialization and make graphs using matplotlib.
