 Overview

In this project multiprocessing & multithreading C programs are created to process multiple data sets. These programs read datasets and returns the words with the highest frequencies along with their counts for each dataset. Data sets are stored in files that consists of any words separated by whitespace. The programs are able to process any number of data sets that are passed through from the command line.

The programs perform calculations concurrently using multiple processes and multiple threads.


Documentation

 Multi-process Programming

For each data set, the program creates a child process. Each child process first reads all data from the file, perform the calculations, and sends the statistics back to the main process via a Unix pipes. Finally, the program prints out the results in a tabular format.

 Multi-threaded Programming

The program creates a thread to process each data set. Each thread perform operations for its data set and passes them to the parent thread. The program then waits for all threads to finish and print out all results in a tabular format.
