  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.

 Introducing temporal behavior into computer science also explains why only the extreme scale computing enabled us to reveal the experienced limitations.
