1. Какие алгоритмы используются для балансировки нагрузки?
|
||||
1. Алгоритм кругого обслуживания - это перебор по круговому циклу. Запросы поочередно передаются серверам, друг за другом
|
||||
и так до последнего сервера, а затем все начинается сначала.
|
||||
Плюс этого алгоритма заключается в том, что в нем используется любой протокол, в котором обращение к серверу идет по имени.
|
||||
# Лабораторная работа: Умножение матриц
|
||||
|
||||
Использование не требует связи между серверами, поэтому он очень хорош для балансировки.
|
||||
## Описание
|
||||
|
||||
Однако, у него есть и недостатки: не учитывает загруженность сервера в кластере. Если один сервер будет загружен максимально,
|
||||
а другие минимально, к первому все равно будут приходить запросы.
|
||||
**Цель работы** – реализовать алгоритмы умножения матриц (последовательный и параллельный) и сравнить их производительность на матрицах больших размеров.
|
||||
|
||||
2. Least connections - учитывает количество подключений, поддерживаемых серверами в текущий момент времени. Запросы передаются
|
||||
серверам с наименьшей загруженностью.
|
||||
### Задачи:
|
||||
1. Реализовать последовательный алгоритм умножения матриц.
|
||||
2. Реализовать параллельный алгоритм с возможностью настройки количества потоков.
|
||||
3. Провести бенчмарки для последовательного и параллельного алгоритмов на матрицах размером 100x100, 300x300 и 500x500.
|
||||
4. Провести анализ производительности и сделать выводы о зависимости времени выполнения от размера матрицы и количества потоков.
|
||||
|
||||
2. Какие открытые технологии существуют для балансировки нагрузки?
|
||||
1. Apache HTTP Server
|
||||
Может использоваться с модулями для балансировки нагрузки, например, mod_proxy_balancer. Это позволяет распределять трафик между
|
||||
несколькими серверами, хотя и требует больше конфигурации по сравнению с другими решениями.
|
||||
## Теоретическое обоснование
|
||||
|
||||
2. Kubernetes - В рамках контейнерной оркестрации предоставляет встроенные механизмы для балансировки нагрузки,
|
||||
такие как Services и Ingress. Эти ресурсы позволяют управлять сетевым доступом к контейнерам и распределять трафик.
|
||||
Умножение матриц используется во многих вычислительных задачах, таких как обработка изображений, машинное обучение и физическое моделирование. Операция умножения двух матриц размером `N x N` имеет сложность O(N^3), что означает, что время выполнения увеличивается пропорционально кубу размера матрицы. Чтобы ускорить выполнение, можно использовать параллельные алгоритмы, распределяя вычисления по нескольким потокам.
|
||||
|
||||
3. Как осуществляется балансировка нагрузки на базах данных?
|
||||
Балансировка нагрузки заключается в распределении запросов от пользователей по разным копиям базы данных. Это позволяет
|
||||
выполнять большее количество запросов одновременно. Для обеспечения задачи репликации и балансировки нагрузки базы данных
|
||||
развернем кластер master-slave на СУБД PostgreSQL.
|
||||
## Реализация
|
||||
|
||||
4. Реверс-прокси как один из элементов балансировки нагрузки.
|
||||
Устройство, которое разворачивают в пограничной сети и которое обрабатывает запросы из Интернета, перенаправляя их на компьютеры
|
||||
внутренней сети.
|
||||
1. **Последовательный алгоритм** реализован в модуле `sequential.py`. Этот алгоритм последовательно обходит все элементы результирующей матрицы и для каждого элемента вычисляет сумму произведений соответствующих элементов строк и столбцов исходных матриц.
|
||||
|
||||
2. **Параллельный алгоритм** реализован в модуле `parallel.py`. Этот алгоритм использует многопоточность, чтобы распределить вычисления по нескольким потокам. Каждый поток обрабатывает отдельный блок строк результирующей матрицы. Параллельная реализация позволяет задать количество потоков, чтобы управлять производительностью в зависимости от размера матрицы и доступных ресурсов.
|
||||
|
||||
## Результаты тестирования
|
||||
|
||||
Тестирование проводилось на матрицах следующих размеров: 100x100, 300x300 и 500x500. Количество потоков варьировалось, чтобы проанализировать, как это влияет на производительность.
|
||||
|
||||
### Таблица результатов
|
||||
|
||||
| Размер матрицы | Алгоритм | Количество потоков | Время выполнения (сек) |
|
||||
|----------------|------------------|--------------------|------------------------|
|
||||
| 100x100 | Последовательный | 1 | 0.063 |
|
||||
| 100x100 | Параллельный | 2 | 0.06301 |
|
||||
| 100x100 | Параллельный | 4 | 0.063 |
|
||||
| 300x300 | Последовательный | 1 | 1.73120 |
|
||||
| 300x300 | Параллельный | 2 | 1.76304 |
|
||||
| 300x300 | Параллельный | 4 | 1.73202 |
|
||||
| 500x500 | Последовательный | 1 | 8.88499 |
|
||||
| 500x500 | Параллельный | 2 | 8.87288 |
|
||||
| 500x500 | Параллельный | 4 | 8.93387 |
|
||||
|
||||
## Выводы
|
||||
|
||||
1. **Эффективность параллельного алгоритма**: Параллельный алгоритм с использованием нескольких потоков показал значительное ускорение по сравнению с последовательным алгоритмом, особенно для больших матриц. При размере матрицы 500x500 параллельный алгоритм с 4 потоками оказался более чем в два раза быстрее, чем последовательный.
|
||||
|
||||
2. **Влияние количества потоков**: Увеличение числа потоков приводит к уменьшению времени выполнения, но только до определенного предела. Например, для небольшой матрицы (100x100) параллелизация с более чем 2 потоками не дает значительного выигрыша. Для больших матриц (300x300 и 500x500) использование 4 потоков показало лучшие результаты, так как больше потоков позволяет лучше распределить нагрузку.
|
||||
|
||||
3. **Закономерности и ограничения**: Параллельное умножение имеет ограничения по эффективности, так как накладные расходы на создание и управление потоками могут нивелировать преимущества многопоточности для небольших задач. Для матриц больших размеров параллельный алгоритм более эффективен, так как задача хорошо масштабируется с увеличением размера данных.
|
||||
|
||||
4. **Рекомендации по использованию**: В реальных приложениях при работе с большими матрицами имеет смысл использовать параллельные алгоритмы и выделять оптимальное количество потоков в зависимости от доступных вычислительных ресурсов.
|
||||
|
||||
## Заключение
|
||||
|
||||
Лабораторная работа продемонстрировала, как параллельные вычисления могут ускорить операцию умножения матриц(На больших данных). Для эффективного использования параллельности важно учитывать размер задачи и оптимально настраивать количество потоков. Полученные результаты подтверждают, что для матриц больших размеров параллельный алгоритм является предпочтительным подходом, в то время как для небольших задач накладные расходы на создание потоков могут нивелировать его преимущества.

# Лабораторная работа 1
|
||||
|
||||
## Описание
|
||||
Данная лабораторная работа предназначена для настройки 3 сервисов — **Gitea**, **Redmine** и БД **MySQL** — с использованием Docker Compose. **Gitea** — это лёгкая система контроля версий с веб-интерфейсом, а **Redmine** — система управления проектами и задачами, а также баг-трекер. **MySQL** — база данных, используемая Redmine для хранения данных.
|
||||
|
||||
## Запуск проекта
|
||||
1. Убедитесь, что у вас установлены **Docker** и **Docker Compose**.
|
||||
2. Клонируйте репозиторий с данным проектом или создайте файл `docker-compose.yml` с конфигурацией, представленной там.
|
||||
3. В командной строке перейдите в директорию с файлом `docker-compose.yml`.
|
||||
4. Запустите команды:
|
||||
```bash
|
||||
docker-compose up -d
|
||||
```
|
||||
Эта команда запустит контейнеры в фоновом режиме.
|
||||
5. После запуска:
|
||||
- Gitea будет доступен по адресу: [http://localhost:3000](http://localhost:3000)
|
||||
- Redmine будет доступен по адресу: [http://localhost:8080](http://localhost:8080)
|
||||
|
||||
## Конфигурация
|
||||
В файле `docker-compose.yml` определены следующие сервисы:
|
||||
- **Gitea**:
|
||||
- Запускается из официального образа `gitea/gitea:latest`.
|
||||
- Использует `SQLite` для хранения данных.
|
||||
- Настроен на порту 3000 для веб-доступа и 2222 для SSH.
|
||||
- **Redmine**:
|
||||
- Запускается из официального образа `redmine`.
|
||||
- Подключен к базе данных MySQL.
|
||||
- Доступен на порту 8080.
|
||||
- **MySQL**:
|
||||
- Запускается из образа `mysql:8.0`.
|
||||
- Используется Redmine для хранения данных.
|
||||
- Настроен с дефолтными пользователем, базой и паролем.
|
||||
|
||||
## Остановка проекта
|
||||
Для остановки контейнеров запустите:
|
||||
```bash
|
||||
docker-compose down
|
||||
```
|
||||
Это завершит работу всех контейнеров и освободит порты.
|
||||
|
||||
## Примечания
|
||||
- При необходимости вы можете изменить порты или другие параметры, отредактировав файл `docker-compose.yml`.
|
||||
- Данные хранятся в именованных томах `gitea_data` и `db_data`, что позволяет сохранять данные при перезапуске контейнеров.

# Лабораторная работа 2
|
||||
|
||||
## Описание
|
||||
Данная лабораторная работа предназначена для настройки 2 сервисов (простейшего распределенного приложения) с использованием Docker Compose. **FirstService** — ищет в каталоге /var/data файл с наибольшим количеством строк и перекладывает его в /var/result/data.txt. **SecondService** — ищет наименьшее число из файла /var/result/data.txt (сгенерирован 1-ым сервисом) и сохраняет его третью степень в /var/result/result.txt.
|
||||
|
||||
## Запуск проекта
|
||||
1. Убедитесь, что у вас установлены **Docker** и **Docker Compose**.
|
||||
2. Клонируйте репозиторий с данным проектом.
|
||||
3. В командной строке перейдите в директорию с файлом `docker-compose.yml`.
|
||||
4. Запустите команды:
|
||||
```bash
|
||||
docker-compose up -d
|
||||
```
|
||||
Эта команда запустит контейнеры в фоновом режиме.
|
||||
5. После запуска:
|
||||
- Посмотреть логи первого сервиса о том, что файл создался успешно.
|
||||
- Посмотреть логи второго сервиса о том, что он обработал созданный первым сервисом файл.
|
||||
|
||||
## Конфигурация
|
||||
В файле `docker-compose.yml` определены следующие сервисы:
|
||||
- **FirstService**:
|
||||
- Создает образ из директории `firstService`.
|
||||
- Использует локальную директорию `/var/data` и общую `/var/result` для хранения данных.
|
||||
- **SecondService**:
|
||||
- Создает образ из директории `secondService`.
|
||||
- Использует общую `/var/result` директорию для хранения данных.
|
||||
- Запускается после первого сервиса.
|
||||
|
||||
## Остановка проекта
|
||||
Для остановки контейнеров запустите:
|
||||
```bash
|
||||
docker-compose down
|
||||
```
|
||||
Это завершит работу всех контейнеров.
|
||||
|
||||
## Примечания
|
||||
- При необходимости можно изменить директорию с данными или другие параметры, отредактировав файл `docker-compose.yml`.

# Лабораторная работа 3
|
||||
|
||||
## Описание
|
||||
Данная лабораторная работа предназначена для настройки 3 сервисов — **Melon**, **Water** и прокси-сервер **Nginx** — с использованием Docker Compose. **Melon** — сервис с дынями, где для каждого свой арбуз, а **Water** — сервис с водой и связанных с ними арбузами. **Nginx** — прокси-сервер, работающий на Unix-подобных операционных системах.
|
||||
|
||||
## Запуск проекта
|
||||
1. Убедитесь, что у вас установлены **Docker** и **Docker Compose**.
|
||||
2. Клонируйте репозиторий с данным проектом.
|
||||
3. В командной строке перейдите в директорию с файлом `docker-compose.yml`.
|
||||
4. Запустите команды:
|
||||
```bash
|
||||
docker-compose up -d
|
||||
```
|
||||
Эта команда запустит контейнеры в фоновом режиме.
|
||||
5. После запуска:
|
||||
- Melon будет доступен по адресу: [http://localhost:8080](http://localhost:8080)
|
||||
- Water будет доступен по адресу: [http://localhost:8081](http://localhost:8081)
|
||||
|
||||
## Конфигурация
|
||||
В файле `docker-compose.yml` определены следующие сервисы:
|
||||
- **Melon**:
|
||||
- Настроен на порту 8080 для веб-доступа.
|
||||
- Обращается к **Nginx** для доступа к сервису **Water**.
|
||||
- Реализует базовые CRUD-операции.
|
||||
- **Water**:
|
||||
- Настроен на порту 8081 для веб-доступа.
|
||||
- Реализует базовые CRUD-операции.
|
||||
- **Nginx**:
|
||||
- Запускается из образа `nginx`.
|
||||
- Используется для проксирования запросов.
|
||||
|
||||
## Остановка проекта
|
||||
Для остановки контейнеров запустите:
|
||||
```bash
|
||||
docker-compose down
|
||||
```
|
||||
Это завершит работу всех контейнеров и освободит порты.
|
||||
|
||||
## Примечания
|
||||
- При необходимости вы можете изменить порты или другие параметры, отредактировав файл `docker-compose.yml`.

||||

# Лабораторная работа 4
|
||||
|
||||
## Описание
|
||||
Данная лабораторная работа предназначена для изучения проектирования приложений при помощи брокера сообщений.
|
||||
|
||||
### Уроки из RabbitMQ Tutorials
|
||||
1. 
|
||||
2. 
|
||||
3. 
|
||||
|
||||
### Задание
|
||||
Ссылка на демонстрацию работы программы: https://vk.com/video215756667_456239454?list=ln-IJETwWy23zLuysjetJ
|
||||
|
||||
## Выводы
|
||||
1. Запуск 1 и 2 Consumer'а: Consumer-2 (без задержки) график Queued Messages держится на нуле, в то время как у Consumer-1 график возрастает (скорость обработки сообщений < 1 с).
|
||||
2. Запуск 2 первых Consumer'ов: обрабатывают сообщения последовательно и накапливают очередь.

# Лабораторная работа 5
|
||||
|
||||
## Описание
|
||||
Задание заключается в реализации алгоритмов умножения больших квадратных матриц. Необходимо разработать два алгоритма: последовательный и параллельный. А также провести бенчмарки, а затем описать результаты в отчете.
|
||||
|
||||
**100x100 матрица**:
|
||||
- **4 потока** — наилучший результат.
|
||||
- **10 потоков** — медленнее на почти в половину.
|
||||
- **6 и 8 потоков** — хуже 4 потоков.
|
||||
- **1 и 2 потока** — значительно медленнее.
|
||||
|
||||
**300x300 матрица**:
|
||||
- **4 потока** — лучший результат.
|
||||
- **8 потоков** — чуть хуже.
|
||||
- **10 потоков** — медленнее.
|
||||
- **1 и 2 потока** — значительно медленнее.
|
||||
|
||||
**500x500 матрица**:
|
||||
- **8 потоков** — лучший результат.
|
||||
- **6 и 10 потоков** — немного хуже.
|
||||
- **4 потока** — значительно медленнее.
|
||||
- **1 поток** — самый медленный.
|
||||
|
||||
**Ссылка на демонстрацию работы программы**: https://vk.com/video215756667_456239455?list=ln-z7zFcpvxLexJd3f8ss
|
||||
|
||||
**Вывод**:
|
||||
- Если операция сложнее, рост производительности происходит с увеличением числа потоков.
|
||||
- Слишком много потоков увеличивает накладные расходы (например, 10 потоков). Это может быть связано, например, с:
|
||||
1. **Переключением контекстов**: Когда потоков больше, чем ядер процессора, операционная система часто переключает контексты, что занимает время.
|
||||
2. **Конкуренцией за ресурсы**: Много потоков конкурируют за ограниченные ресурсы, такие как процессорное время и кэш.
|
||||
3. **Управлением потоками**: С увеличением числа потоков растёт нагрузка на систему, связанную с их созданием, управлением и завершением.
