Overview

This program calculates the Jenkins hash of a file using a multithreaded approach with a binary tree structure. The program leverages memory mapping and threads to process file blocks simultaneously, ensuring efficient computation.

Files

• ho.c: Main program file containing the implementation.
• common.h: Utility functions for timing and spinning.
• common_threads.h: Wrapper functions for pthread operations to ensure error checking.

Features

• Multithreaded execution using a binary tree structure.
• Memory mapping for efficient file access.
• Recursive thread creation to compute hashes.
• Robust error handling and memory management.

Build Instructions

To compile the program, run the following command:

gcc -o hash_calculator ho.c -lpthread

Usage

To run the program, use the following command:

./hash_calculator <filename> <numThreads>

< filename >: Path to the file to be hashed.

< numThreads >: Number of threads to use for hashing.
