High-Performance Multi-Threaded SHA-256 Server

This project implements a high-performance, multi-threaded C server for computing the SHA-256 hash of files.
The server is designed to handle multiple clients concurrently, using a robust architecture based on FIFO communication and Pthreads for task parallelization.

The goal is to deliver an efficient and scalable service by optimizing resource usage through:

• Caching system
• Intelligent request scheduling (Shortest-Job-First)
• Strict concurrency control

🛠️ Build Instructions

Prerequisites

Make sure the following dependencies are installed:

• build-essential (for make and gcc)
• cmake
• libssl-dev (for OpenSSL)

Example (Ubuntu/Debian):

sudo apt update
sudo apt install build-essential cmake libssl-dev

# 1. Create a build directory
mkdir build

# 2. Enter the build directory
cd build

# 3. Configure the project
cmake ..

# 4. Compile the project
make

After successful compilation, the executables will be available in the bin/ directory.

Execution

All commands should be executed from the project’s root directory.

1. Run the Server

Open a terminal and start the server:

./bin/server

2. Run the Client

Open a second terminal and run the client, specifying the filename:

./bin/client test1KB.txt

Running Tests

The project includes several test scripts (.sh) located in the root directory.
Before running them, make them executable:

chmod +x ./*.sh

Then, you can execute the test scripts normally:
./test_script.sh
