Описание
Реализованы последовательная и параллельная версии алгоритма умножения матрицы на вектор на основе ленточной вертикальной схемы.
Последовательная версия: генерация матрицы A и вектора v, вычисление произведения для каждой строки через вложенные циклы.
Параллельная версия (MPI) использует вертикальную ленточную схему: матрица делится на блоки столбцов между процессами, каждый процесс вычисляет частичные суммы для своих столбцов, после чего результаты собираются через MPI_Allreduce.
В отчёте приведено описание алгоритмов, схема распараллеливания, результаты функциональных тестов и измерения производительности
