Programming Homework Help

First Part:

By Day 7, modify the Java program by adding threads, and analyze the performance of both the threaded and non-threaded versions.

• Modify the Program:

  Improve the performance of the Java program by adding threads to the Sort.java file. Implement the threadedSort() method within the Sort class. Reuse any of the existing methods by calling them as necessary from your threadedSort method. You may add additional methods to the Sort class, if necessary.

Second Part:

For this Assignment, you will consider the I/O performed in the threaded sort Assignment from Week 2 and how the I/O contributes to the performance of the threaded sort. Applying the principles identified in this week’s reading, along with the concurrency control mechanisms from Week 3, you will revise the threaded sort application in an effort to improve the I/O performance in order to affect an overall performance improvement.

To prepare:

• Evaluate the manner by which the threaded sort application performs I/O to retrieve the data to be sorted.
• Propose a strategy to improve the performance by applying one or more of the principles to improve the efficiency of I/O that were identified in this week’s reading.

By Day 7, implement your strategy by modifying your solution to the threaded sort Assignment from Week 2.

In addition, write a 2- to 3-page paper that evaluates how I/O performance impacts overall program performance. Make sure to include the following:

• A description of your I/O strategy
• An explanation on how you expected your strategy to improve performance
• A summary of the actual change in performance observed when running the updated threaded sort
