Looking at your current patch version, I noticed this line in parallel-for.h:
+ if (n_threads > 1 && 2 * n_threads >= n_elements)
I am fairly sure this should be <= in the threads comparison,
otherwise you only use threads if there are few elements, which is the
opposite of what is desired (perhaps a merge error?)
