hardware_constructive_interference_size

constexpr std::size_t hardware_constructive_interference_size = 64u

This is BioDynaMo's cacheline size. If you system has a different cacheline size, consider changing the value accordingly. In particular, this value is used to align the data in the SharedData class to avoid false sharing between threads. From C++17 on, the standard library provides hardware_constructive_interference_size and hardware_destructive_interference_size, which can be used instead of this constant. If the standard library does not provide these constants, the default value for x86-64 is used.
