Задача вычисления сумм по столбцам матрицы. На вход подается матрица целых чисел, на выходе - вектор сумм каждого столбца. Реализованы две версии: последовательная (SEQ) и параллельная (MPI). SEQ версия проходит по всем элементам матрицы, суммируя значения столбцов. MPI версия распределяет строки матрицы между процессами, каждый процесс вычисляет частичные суммы для своих строк, затем результаты собираются на процессе 0. Обрабатываются все случаи включая пустые матрицы, матрицы с отрицательными числами и различные размеры матриц.
