# Отчет по лабораторной работе №5
|
||||
|
||||
Выполнил студент гр. ИСЭбд-41 Миронов Е.О.
|
||||
|
||||
## Создание приложения
|
||||
|
||||
Выбрал язык C#, Консольное приложение.
|
||||
|
||||
Проверяю правильность работы алгоритма
|
||||
|
||||
```c#
|
||||
public int[][] MultiplicationMatrix(int[,] firstMatrix, int[,] secondMatrix, int threadCount = 1)
|
||||
{
|
||||
var resultMatrix = new ConcurrentDictionary<int, int>[firstMatrix.GetLength(0)]
|
||||
.Select(x => new ConcurrentDictionary<int, int>())
|
||||
.ToArray();
|
||||
|
||||
for (int i = 0; i < firstMatrix.GetLength(0); i++)
|
||||
{
|
||||
Parallel.For(0, secondMatrix.GetLength(1), new ParallelOptions()
|
||||
{
|
||||
MaxDegreeOfParallelism = threadCount
|
||||
},
|
||||
(j) =>
|
||||
{
|
||||
|
||||
for (int k = 0; k < secondMatrix.GetLength(0); k++)
|
||||
{
|
||||
resultMatrix[i].AddOrUpdate(
|
||||
j,
|
||||
firstMatrix[i, k] * secondMatrix[k, j],
|
||||
(key, value) => value + firstMatrix[i, k] * secondMatrix[k, j]);
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
return resultMatrix
|
||||
.Select(x => x.Values.ToArray())
|
||||
.ToArray();
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
## Бенчмарки
|
||||
|
||||
Делаю 9 пробных запусков
|
||||
Матрицы 10х10, 100х100, 1000х1000
|
||||
Количество потоков 1,5,15
|
||||
|
||||
|
||||
|
||||
|
||||
Предполагал что 15 потоков хватит, чтобы показать что бывает когда кол-во потоков в приложении больше кол-ва потоков в процессоре.
|
||||
|
||||
Однако этого не произошло, поэтому запускаю следующий тест на 55 потоков
|
||||
|
||||
|
||||
|
||||
Наблюдаем увелечение времени обработки. Это связано с с затратами на переключение контекста, синхронизацию потоков и т.п.
|
||||
|
||||
|
||||
Вывод: Параллельный алгоритм работает быстрее чем однопоточный в случае если ресурсы процесора это позволяют.
|
||||
В случае указания слишком большого числа потоков параллелльный алгоритм будет работать чуть медленее из-за накладных расходов на переключение контекста синхронизации и т.д.
