# Отчет по лабораторной работе №5
|
||||
|
||||
Выполнил студент гр. ИСЭбд-41 Савицкий А.В.
|
||||
|
||||
## Создание приложения
|
||||
|
||||
Выбрал язык C#, Консольное приложение.
|
||||
|
||||
Проверяю правильность работы алгоритма
|
||||
|
||||
```cs
|
||||
public int[,] MultiplicationMatrix(int[,] matrix1, int[,] matrix2, int threadCount)
|
||||
{
|
||||
var result = new int[matrix1.GetLength(0), matrix1.GetLength(1)];
|
||||
for(int i = 0; i < result.GetLength(0); i++)
|
||||
{
|
||||
for (int j = 0; j < result.GetLength(1); j++)
|
||||
{
|
||||
result[i, j] = 0;
|
||||
}
|
||||
}
|
||||
|
||||
for (int i = 0; i < matrix1.GetLength(0); i++)
|
||||
{
|
||||
Parallel.For(0, matrix2.GetLength(1), new ParallelOptions() { MaxDegreeOfParallelism = threadCount },
|
||||
(j) =>
|
||||
{
|
||||
|
||||
for (int k = 0; k < matrix2.GetLength(0); k++)
|
||||
{
|
||||
var value = matrix1[i, k] * matrix2[k, j];
|
||||
Interlocked.Add(ref result[i, j], value);
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
return result;
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
|
||||
Установил библиотеку BenchmarkDotNet для замера производительности алгоритма.
|
||||
|
||||
## Бенчмарки
|
||||
|
||||
Делаю 6 пробных запусков
|
||||
Матрицы 100х100, 300х300, 500х500
|
||||
Количество потоков 1,12
|
||||
|
||||
|
||||
|
||||
Нас интересуют преимущественно две колонки - Mean и Allocated.
|
||||
|
||||
Mean показывает среднее время выполнения бенчмарка
|
||||
Allocated показывает количество выделенной памяти
|
||||
|
||||
Для матриц 100х100 однопоточный алгоритм отработал быстрее чем многопоточный, однако для более больших матриц время выполнения серьезно уменшилось.
|
||||
|
||||
Вывод: Параллельный алгоритм работает быстрее чем однопоточный, если мы обрабатываем большие данные. Также многопоточное выполнение занимает больше памяти.
