To improve memory access: Refactor your code to alert the compiler to a regular stride access. Sometimes, it might be beneficial to use the ipo/Qipo compiler option to enable interprocedural optimization (IPO) between files.

An array is the most common type of data structure containing a contiguous collection of data items that can be accessed by an ordinal index. You can organize this data as an array of structures (AoS) or as a structure of arrays (SoA). Detected constant stride might be the result of AoS implementation. While this organization is excellent for encapsulation, it can hinder effective vector processing. To fix: Rewrite code to organize data using SoA instead of AoS.
