The SoA Vector – Part 2: Implementation in C++ by Sidney Congard

From the article:

Like we saw in the first part of this series on SoA, the SoA is a way to organise the data of a collection of objects to optimise the performance of certain use cases: traversing the collection by accessing the same data member of all the objects: struct person
std::string name;
int age;
;

std::vector<person> persons = ...

for (auto& person : persons)

++person.age;

struct person
std::string name;
int age;
;

std::vector<person> persons = ...

for (auto& person : persons)

++person.age;
The SoA in its barest expression is this: (...)

The SoA Vector – Part 1: Optimizing the Traversal of a Collection by Sidney Congard

From the article:

I like C++ because it offers a good compromise between writing expressive and fast code. But, I discovered a problem where I didn’t know any way to hide the implementation detail away from its use: The “Structure of Arrays” (SoA) versus the “Array of Structures” (AoS) problem. This is the first part of a series of two articles: what ‘SoA’ is about and what benefits it brings (part 1) how to implement an SoA vector in C++ (part 2) So let’s see what those SoA and AoS are all (...)
