# Отчёт по лабораторной работе №5
|
||||
|
||||
Выполнил: студент гр. ИСЭбд-41 Михайлов Ю.С.
|
||||
|
||||
## Запуск приложения
|
||||
|
||||
Было выбрано консольное приложение, язык программирования - C#.
|
||||
|
||||
Перемножение матриц обычным алгоритмом:
|
||||
```
|
||||
public static int[][] MultiplySequential(int[][] matrixA, int[][] matrixB)
|
||||
{
|
||||
int rowsA = matrixA.Length;
|
||||
int colsA = matrixA[0].Length;
|
||||
int colsB = matrixB[0].Length;
|
||||
|
||||
int[][] result = new int[rowsA][];
|
||||
|
||||
for (int i = 0; i < rowsA; i++)
|
||||
{
|
||||
result[i] = new int[colsB];
|
||||
|
||||
for (int j = 0; j < colsB; j++)
|
||||
{
|
||||
for (int k = 0; k < colsA; k++)
|
||||
{
|
||||
result[i][j] += matrixA[i][k] * matrixB[k][j];
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
return result;
|
||||
}
|
||||
```
|
||||
|
||||
Перемножение матриц параллельным алгоритмом:
|
||||
```
|
||||
public static int[][] MultiplyParallel(int[][] matrixA, int[][] matrixB, int numThreads)
|
||||
{
|
||||
int rowsA = matrixA.Length;
|
||||
int colsA = matrixA[0].Length;
|
||||
int colsB = matrixB[0].Length;
|
||||
|
||||
int[][] result = new int[rowsA][];
|
||||
|
||||
Parallel.For(0, rowsA, new ParallelOptions { MaxDegreeOfParallelism = numThreads }, i =>
|
||||
{
|
||||
result[i] = new int[colsB];
|
||||
|
||||
for (int j = 0; j < colsB; j++)
|
||||
{
|
||||
for (int k = 0; k < colsA; k++)
|
||||
{
|
||||
result[i][j] += matrixA[i][k] * matrixB[k][j];
|
||||
}
|
||||
}
|
||||
});
|
||||
|
||||
return result;
|
||||
}
|
||||
```
|
||||
|
||||
## Результаты
|
||||
|
||||
|
||||
Вывод: если в матрице не слишком много элементов, обычный алгоритм работает быстрее. Параллельный алгоритм следует использовать для обработки большого количества данных. В сравнении с однопоточным алгоритмом, работа параллельного в несколько раз быстрее.
