At the end of each simulation LAMMPS reports a breakdown of its effort and if "timer full" is used even more information like the threads effort breakdown is also reported.
I was wondering if you could explain what "Modify" and "Reduce" sections of the task breakdown refer to?

modify is caused by fixes and computes (if called by fixes, which is
typical)
reduce applies to USER-OMP and is the time spent in doing the reduction of
the per-thread force arrays.
