Before revision:   The paper shows that the degradation of the efficiency of the parallelized sequential system is a natural consequence of the  computing paradigm, rather than an engineering imperfectness.
After revision:  Introducing temporal behavior into computer science also explains why only the extreme scale computing enabled us to reveal the experienced limitations.
