Amdahl's law

Amdahl's law
закон Амдала
американский конструктор суперкомпьютеров Gene Myron Amdahl в 1967 г. сформулировал закон, гласящий, что ускорение вычислений (повышение производительности), которое может быть достигнуто путём распределения (распараллеливания) операций программы между p процессорами, не может превысить 1/(f + (1 - f)/p), где f - доля работы программы, выполняемая в последовательном режиме
