# Отчет по лабораторной работе №3
|
||||
|
||||
Выполнила студентка гр. ИСЭбд-41 Островская С. Ф.
|
||||
|
||||
## REST API, Gateway и синхронный обмен между микросервисами
|
||||
|
||||
## Создание микросервисов
|
||||
|
||||
1. Создала первый микросервис - `dotnet new web -n worker-1`
|
||||
2. Добавила решение - `dotnet new sln`
|
||||
3. Связала решение и проект - `dotnet sln worker-1.sln add worker-1.csproj`
|
||||
4. Для второго микросервиса выполнила пункты 1-3
|
||||
5. Добавила библиотеку Swagger и OpenAi - `dotnet add worker-1.csproj package Swashbuckle.AspNetCore` , `dotnet add worker-1.csproj package Microsoft.AspNetCore.OpenApi`
|
||||
6. Запустила - `dotnet run`
|
||||
|
||||
Скриншоты протестированных микросервисов:
|
||||
|
||||
|
||||
|
||||
## Реализация синхронного обмена
|
||||
|
||||
Код реализации синхронного обмена:
|
||||
|
||||
```cs
|
||||
//Файд Program.cs проекта worker-2
|
||||
app.MapGet("/Requests/", async () =>
|
||||
{
|
||||
var httpClient = new HttpClient();
|
||||
var secondWorkerResponse = await httpClient.GetStringAsync("http://worker-1:8080/");
|
||||
|
||||
return secondWorkerResponse.ToArray();
|
||||
})
|
||||
.WithName("GetRequests")
|
||||
.WithOpenApi();
|
||||
```
|
||||
|
||||
## Реализация gateway при помощи nginx
|
||||
|
||||
Добавила nginx.conf:
|
||||
|
||||
```conf
|
||||
server {
|
||||
listen 8080;
|
||||
listen [::]:8080;
|
||||
server_name localhost;
|
||||

||||
location / {
|

# Отчет по лабораторной работе №6
|
||||
|
||||
Выполнила студентка гр. ИСЭбд-41 Островская С. Ф.
|
||||
|
||||
## Создание приложения
|
||||
|
||||
Было выбрано консольное приложение, язык программирования - c#.
|
||||
|
||||
Обычный алгоритм:
|
||||
|
||||
```cs
|
||||
static void SequentialDeterminantCalculation(int matrixSize, int lowerLimit, int upperLimit)
|
||||
{
|
||||
int[][] randomMatrix = GenerateRandomMatrix(matrixSize, lowerLimit, upperLimit);
|
||||
|
||||
Stopwatch stopwatch = new Stopwatch();
|
||||
stopwatch.Start();
|
||||
int result = Determinant(randomMatrix);
|
||||
stopwatch.Stop();
|
||||
TimeSpan elapsedTime = stopwatch.Elapsed;
|
||||
Console.WriteLine($"Последовательный детерминант: {result}");
|
||||
Console.WriteLine($"Последовательное время: {elapsedTime.TotalSeconds:F7} секунд");
|
||||
}
|
||||
```
|
||||
Параллельный алгоритм:
|
||||
|
||||
```cs
|
||||
static void ParallelDeterminantCalculation(int matrixSize, int lowerLimit, int upperLimit, int numProcesses)
|
||||
{
|
||||
int[][] randomMatrix = GenerateRandomMatrix(matrixSize, lowerLimit, upperLimit);
|
||||
|
||||
int[][] matricesToProcess = new int[matrixSize][];
|
||||
for (int col = 0; col < matrixSize; col++)
|
||||
{
|
||||
matricesToProcess[col] = Submatrix(randomMatrix, 0, col)[0];
|
||||
}
|
||||
|
||||
Stopwatch stopwatch = new Stopwatch();
|
||||
stopwatch.Start();
|
||||
int[] determinants = new int[matrixSize];
|
||||
Parallel.For(0, matrixSize, new ParallelOptions { MaxDegreeOfParallelism = numProcesses }, col =>
|
||||
{
|
||||
determinants[col] = Determinant(new int[][] { matricesToProcess[col] });
|
||||
});
|
||||
|
||||
int result = 0;
|
||||
for (int col = 0; col < matrixSize; col++)
|
||||
{
|
||||
result += ((-1) * col) * randomMatrix[0][col] * determinants[col];
|
||||
}
|
||||
stopwatch.Stop();
|
||||
TimeSpan elapsedTime = stopwatch.Elapsed;
|
||||
Console.WriteLine($"Параллельный детерминант: {result}");
|
||||
Console.WriteLine($"Параллельное время: {elapsedTime.TotalSeconds:F7} секунд");
|
||||
}
|
||||
```
|
||||
|
||||
## Бенчмарки
|
||||
|
||||
Для примера была взята матрица размерностью 10х10, поскольку для матриц больших размеров детерминант вычисляется слишком долго.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
``Вывод``: Обыный алгоритм работает быстрее, если количество элементов не слишком много. Параллельный же алгоритм работает быстрее только при наличии большого количества операций и данных.
