Задание
Задача: Умножение разреженных матриц. Формат хранения CRS.
Вариант: 4
Технология: MPI (с поддержкой SEQ для последовательной версии)
Описание
Реализованы последовательная и параллельная версии алгоритма умножения разреженных матриц в формате CRS (Compressed Row Storage).
Последовательная версия (SEQ) выполняет умножение строк матрицы A на столбцы матрицы B через временный вектор.
Параллельная версия (MPI) распределяет строки матрицы A между процессами по схеме round-robin. Матрица B полностью рассылается всем процессам через MPI_Bcast. Каждый процесс вычисляет своё подмножество строк результата, после чего root собирает результаты через MPI_Send/MPI_Recv.
