# Отчет по лабораторной работе №3
|
||||
|
||||
Выполнила студентка гр. ИСЭбд-41 Зиновьева А. Д.
|
||||
|
||||
## 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
|
||||
//Файл 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 / {
|
||||
root /usr/share/nginx/html;
|
||||
index index.html index.htm;
|
||||
}
|
||||
|
||||
location /worker-1/ {
|
||||
proxy_pass http://worker-1:8080/;
|
||||
proxy_set_header Host $host;
|
||||
proxy_set_header X-Real-IP $remote_addr;
|
||||
proxy_set_header X-Forwarded-Proto $scheme;
|
||||
proxy_set_header X-Forwarded-Prefix /worker-1;
|
||||
}
|
||||
|
||||
location /worker-2/ {
|
||||
proxy_pass http://worker-2:8080/;

proxy_set_header Host $host;

proxy_set_header X-Forwarded-Proto $scheme;
|
||||
proxy_set_header X-Forwarded-Prefix /worker-2;
|
||||
}
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
Результат, после выполнения команды `docker compose up`:

# Отчет по лабораторной работе №6
|
||||
|
||||
Выполнила студентка гр. ИСЭбд-41 Зиновьева А. Д.
|
||||
|
||||
## Создание приложения
|
||||
|
||||
Было выбрано консольное приложение, язык программирования - c#.
|
||||
|
||||
Обычный алгоритм:
|
||||
|
||||
```cs
|
||||
static double CalculateDeterminantSequential(int[,] matrix)
|
||||
{
|
||||
int size = matrix.GetLength(0);
|
||||
double determinant = 0;
|
||||
|
||||
if (size == 1)
|
||||
{
|
||||
determinant = matrix[0, 0];
|
||||
}
|
||||
else if (size == 2)
|
||||
{
|
||||
determinant = matrix[0, 0] * matrix[1, 1] - matrix[0, 1] * matrix[1, 0];
|
||||
}
|
||||
else
|
||||
{
|
||||
for (int j = 0; j < size; j++)
|
||||
{
|
||||
determinant += matrix[0, j] * CalculateMinor(matrix, 0, j) * Math.Pow(-1, j);
|
||||
}
|
||||
}
|
||||
|
||||
return determinant;
|
||||
}
|
||||
```
|
||||
Параллельный алгоритм:
|
||||
|
||||
```cs
|
||||
static double CalculateDeterminantParallel(int[,] matrix, int threads)
|
||||
{
|
||||
int size = matrix.GetLength(0);
|
||||
double determinant = 0;
|
||||
|
||||
if (size == 1)
|
||||
{
|
||||
determinant = matrix[0, 0];
|
||||
}
|
||||
else if (size == 2)
|
||||
{
|
||||
determinant = matrix[0, 0] * matrix[1, 1] - matrix[0, 1] * matrix[1, 0];
|
||||
}
|
||||
else
|
||||
{
|
||||
Parallel.For(0, size, new ParallelOptions { MaxDegreeOfParallelism = threads }, j =>
|
||||
{
|
||||
determinant += matrix[0, j] * CalculateMinor(matrix, 0, j) * Math.Pow(-1, j);
|
||||
});
|
||||
}
|
||||
|
||||
return determinant;
|
||||
}
|
||||
```
|
||||
|
||||
## Бенчмарки
|
||||
|
||||
Для примера была взята матрица размерностью 10х10, поскольку для матриц больших размеров детерминант вычисляется слишком долго.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
``Вывод``: Обычный (последовательный) алгоритм работает быстрее, если количество элементов не слишком много. Параллельный же алгоритм работает быстрее только при наличии большого количества операций и данных.
