Until now, I've used two strategies to summate a std::vector. First, I did the whole math in one thread…
Single Threaded: Summation of a Vector
What is the fastest way to add the elements of a std::vector? This a question that I will pursue in the…
Thread-Safe Initialization of a Singleton
There are a lot of issues with the singleton pattern. I'm aware of that. But the singleton pattern is…
Ongoing Optimization: Relaxed Semantics with CppMem
With the relaxed semantics, we have no synchronizations and ordering constraints on atomic operations.

Ongoing Optimization: A Data Race with CppMem
But we can improve and further improve the acquire-release semantics of the last post. Why should x be…
Ongoing Optimization: Acquire-Release Semantics with CppMem
With the acquire-release semantics, we break the sequential consistency. In the acquire-release semantics,…
Ongoing Optimization: Sequential Consistency with CppMem
With atomic data types, you can tailor your program to your needs and optimize it. But now we are in…

CppMem is an interactive tool for exploring the behavior of small code snippets of the C++ memory model.…
Relaxed Semantics
The relaxed semantics is the end of the scale. The relaxed semantic is the weakest of all memory models…
