Please, double check the test coverage. MPI version is not being invoked

| **Выводы:** | ||
| Полученные результаты демонстрируют несколько ключевых аспектов параллельного выполнения данной задачи на рассматриваемом окружении: | ||
| 1. *эффективное масштабирование до 4 потоков:* при увеличении числа потоков с 1 до 4 наблюдается значительное ускорение (до 2.44x). Это подтверждает, что выбранный алгоритм распараллеливания с использованием OpenMP эффективно распределяет работу между потоками, и накладные расходы не перевешивают выгоду от параллельных вычислений; |

почему потоки? у нас параллелизм на несколдьких процессах, в каждом процессе 1 поток
