Pthreads

Description

Write a program that uses pthreads to perform statistical analysis on a text file. The program must compute the normalized frequency of token occurrences and print out the top n frequent tokens. Here we will consider a token to be text that is separated by white space.

Specifications

• The program must be properly modular and documented appropriately.

• The allowable languages for this assignment are: C or C++.

• The name of the compiled program must be p5.

• The default make target should create both executables.

• The input to the program must be in the form of command line arguments as follows:

  • -h (by itself with no other arguments) print the usage instructions.
  • -t <integer> (required) the number of threads to use.
  • -n <integer> (required) the top most frequent tokens to print.
  • -f <string> (required) the name of the text file.

• Note: if the program has global variable(s) or any kind of mutual exclusion mechanism, then you will receive a failing grade for this assignment.

Turning in the Assignment

For this assignment, you must turn in a zip file of a directory named project5 containing the following files:

• README (containing design decisions and a description of the protocol)
• Makefile
• Source code

Submit the zip file to the appropriate folder on D2L.
