+# Отчет по лабораторной работе №5
+
+Выполнила студентка гр. ИСЭбд-41 Островская С.Ф.
+
+## Создание приложения
+
+Было выбрано консольное приложение, язык программирования - c#.
+
+Обычный алгоритм:
+
+```cs
+static int[][] MultiplyMatrix(int[][] matrix1, int[][] matrix2)
+{
+    int rows = matrix1.Length;
+    int columns = matrix2[0].Length;
+    int[][] result = new int[rows][];
+    for (int i = 0; i < rows; i++)
+    {
+        result[i] = new int[columns];
+        for (int j = 0; j < columns; j++)
+        {
+            result[i][j] = 0;
+            for (int k = 0; k < matrix1[i].Length; k++)
+            {
+                result[i][j] += matrix1[i][k] * matrix2[k][j];
+            }
+        }
+    }
+    return result;
+}
+```
+Параллельный алгоритм:
+
+```cs
+static int[][] MultiplyMatrixParallel(int[][] matrix1, int[][] matrix2, int numThreads)
+{
+    int rows = matrix1.Length;
+    int columns = matrix2[0].Length;
+    int[][] result = new int[rows][];
+
+
+    Parallel.For(0, rows, new ParallelOptions { MaxDegreeOfParallelism = numThreads }, i =>
+    {
+        result[i] = new int[columns];
+        for (int j = 0; j < columns; j++)
+        {
+            result[i][j] = 0;
+            Parallel.For(0, matrix1[i].Length, k =>
+            {
+                result[i][j] += matrix1[i][k] * matrix2[k][j];
+            });
+        }
+    });
+    return result;
+}
+```
+
+![](pic/pic1.jpg)
+![](pic/pic2.jpg)
+
+В результате обычный алгоритм выполнился за ``0,0002112`` секунды, а паралелльный за ``0,0064956`` секунды.
+
+## Бенчмарки
+
+Протестируем обычный и параллельный алгоритмы на матрицах различных размеров: 100х100, 300х300 и 500х500.
+
+Количество потоков: ``4``
+![](pic/pic3.jpg)
+
+Количество потоков: ``12``
+![](pic/pic4.jpg)
+
+``Вывод``: Обыный алгоритм работает быстрее, если количество элементов не слишком много. Параллельный же алгоритм работает быстрее только при наличии большого количества операций и данных. Оптимальное количество потоков для эффективной работы - 12.
