this project is a homework in the paralell processing course.

Multi-Threaded Java web Server

This project contain two types of multi-threaded web servers, both equipped with thread-pooling capabilities, designed to efficiently execute a variety of simple tasks.

Project Structure

• Handler: Manages incoming HTTP requests and routes them to the appropriate task.
• Tasks: Defines individual tasks, each implementing a generic task interface for consistent handling.
• TaskExecutor: Executes the specified task by dynamically instantiating it and processing the input.

How to Run

Running the Server Locally

1. Clone the repository:

   git clone https://github.com/your-username/task-manager-server.git
   cd task-manager-server
   

2. Compile and Run the Project:

   • Use your preferred Java IDE or run from the terminal:

   javac -d bin -sourcepath src src/main/WebServerHttp.java
   java -cp bin main.WebServerHttp
   

   • The server will start on port 8000.

Running with Docker

1. Build the Docker Image:

   docker build -t task-manager-server .
   

2. Run the Docker Container:

   docker run -p 8000:8000 task-manager-server
   

   The server will now be available on localhost:8000.

Sending Requests

You can use curl to send requests to the server. The server supports POST requests for executing tasks and GET requests to view the list of completed tasks.

Example Requests

• Geometric Mean Task:

  curl -X POST http://localhost:8000 -d "TaskGeometricMean&1,2,3,4,5"
  

• Bubble Sort Task:

  curl -X POST http://localhost:8000 -d "TaskBubbleSort&5,3,8,1,2"
  

the new Tasks

• TaskGeometricalMean: Calculate the Geometrical Mean : Geo-Mean = (a₁ × a₂ × ... × a_n)^1/n.

• TaskPrimeNumberFinder: Finds prime numbers up to a specified limit.

Requirements

• Java 8 or higher
• curl (for command-line requests)
• K6 (for test parallel requests)

Testing

You can test the server's performance and concurrency with the tool K6. by running the follwoing commands on the K6TestScripts folder

k6 run testParallelTasks.js

k6 run testHeavyTask.js

k6 run testSingleTaskResponse.js
