# Отчёт по лабораторной работе №6
|
||||
|
||||
Выполнил: студент гр. ИСЭбд-41 Михайлов Юрий.
|
||||
|
||||
## Создание приложения
|
||||
|
||||
Выбран язык C#.
|
||||
|
||||
Запустим алгоритм с матрицей 10x10 c различными алгоритмами.
|
||||

|
||||
|
||||
## Бенчмарки
|
||||
|
||||
Протекстируем обычный и паралелльный с различными размерами матриц.
|
||||
|
||||
Матрица 3х3
|
||||
|
||||
![](picture/2.png)
|
||||
|
||||
Матрица 5х5
|
||||
|
||||
![](picture/3.png)
|
||||
|
||||
Матрица 10х10
|
||||
|
||||
![](picture/1.png)
|
||||
|
||||
|
||||
Вывод: Скоростные возможности параллельного алгоритма проявляются только при значительном количестве операций. В случае, если операций меньше, стандартный алгоритм может оказаться более быстрым.
