StructArrays.jl

Julia has a package that provides incredibility easy to use SoA. https://github.com/JuliaArrays/StructArrays.jl Julia's metaprogramming and multiple dispatch mean that it can use user structs fully transparently. Everything just works.

ISPC also has first class support for "(array of) structure of arrays", see: https://ispc.github.io/ispc.html#structure-of-array-types For example: soa<8> Point pts[...]; declares an array of struct of arrays, where each inner struct array contains 8 elements. This would have the advantage of playing well with the streaming prefetcher if you're working with all fields of the `Point` type, and allowing the compiler to use and increment a single pointer for loading/storing, accessing each field with a small compile time offset (that can get folded into addressing calculations, making them essentially free). Julia's StructArrays package is also very convenient: https://github.com/JuliaArrays/StructArrays.jl
