In order to efficiently use std::vector and friends, a NUMA aware allocator needs to be written.
This work needs to be complemented with a proper NUMA aware executor to allow to iterate over vectors or similar in a memory efficient manner.

We have added parallel::util::numa_allocator (see here), which uses an executor to perform first-touch on the allocated data.
