Do not broadcast the whole matrix, split it on rank 0 and sent by pieces to other ranks

Описание
Разработаны последовательная и параллельная версии программы для поиска максимальных чисел в каждом столбце матрицы. Обычная версия последовательно проходит все столбцы и находит в них максимумы. Параллельная версия использует несколько процессов: каждый процесс получает свои столбцы, находит в них максимумы, а потом все результаты собираются вместе.
Было проведено функциональное производительное тестирования на матрицах 5000×5000 и 10000×10000. Наилучшая производительность достигнута при использовании 2 процессов MPI.
