Description

  • Task: Умножение разреженных матриц. Элементы типа double. Формат хранения матрицы – столбцовый (CCS).
  • Variant: 5
  • Technology: SEQ | MPI
  • Summary: Реализована задача параллельноого умножения разреженных матриц в столбцовом формате CCS с использованием технологии MPI, основная идея заключается в декомпозиции вычислений по столбцам результирующей матрицы: мастер-процесс транспонирует матрицу A для быстрого доступа к данным и рассылает её всем участникам, в то время как столбцы матрицы B распределяются между процессами для независимого формирования локальных фрагментов матрицы C, которые затем эффективно собираются в единую структуру с корректным пересчетом указателей столбцов и фильтрацией нулевых значений.
