Introduction

In this final project you will implement a cache simulator. Your simulator will be configurable and will be able to handle caches with varying capacities, block sizes, levels of associativity, replacement policies, and write policies. The simulator will operate on trace files that indicate memory access properties. All input files to your simulator will follow a specific structure so that you can parse the contents and use the information to set the properties of your simulator.

After execution is finished, your simulator will generate an output file containing information on the number of cache misses, hits, and miss evictions (i.e. the number of block replacements). In addition, the file will also record the total number of (simulated) clock cycles used during the situation. Lastly, the file will indicate how many read and write operations were requested by the CPU.

It is important to note that your simulator is required to make several significant assumptions for the sake of simplicity.

1. You do not have to simulate the actual data contents. We simply pretend that we copied data from main memory and keep track of the hypothetical time that would have elapsed.
2. Accessing a sub-portion of a cache block takes the exact same time as it would require to access the entire block. Imagine that you are working with a cache that uses a 32 byte block size and has an access time of 15 clock cycles. Reading a 32 byte block from this cache will require 15 clock cycles. However, the same amount of time is required to read 1 byte from the cache.
3. In this project assume that main memory RAM is always accessed in units of 8 bytes (i.e. 64 bits at a time).
   When accessing main memory, it’s expensive to access the first unit. However, DDR memory typically includes buffering which means that the RAM can provide access to the successive memory (in 8 byte chunks) with minimal overhead. In this project we assume an overhead of 1 additional clock cycle per contiguous unit.
   For example, suppose that it costs 255 clock cycles to access the first unit from main memory. Based on our assumption, it would only cost 257 clock cycles to access 24 bytes of memory.
4. Assume that all caches utilize a “fetch-on-write” scheme if a miss occurs on a Store operation. This means that you must always fetch a block (i.e. load it) before you can store to that location (if that block is not already in the cache).

Purpose

This discussion activity gives you the opportunity to solve a real world scenario. In doing so, you will learn the concepts of a software development cycle.

Directions

Part I: Complete Your Original Response to the Main Topic

You are a software developer for a Retail Point of Sale System Company. A client has made a request to upgrade the current system from command line interface to a graphic user interface. The client concerns on an effect to the current system with the change. The client does not want to lose any current data on the system. Provide recommendations and the change plan including the below requirements to the customer.

Requirements:

• Create a requirement plan (what need to be done to support this upgrade)
• Create a development plan (how to implement this upgrade with programming details explanation including technical details on this document)
• Create testing plan (how to ensure that the new upgrade works without affecting current system and no data lost.)

Posting your recommendations and the change plan

Once you have completed your recommendations and plan. Post it in the discussion forum by clicking the Reply link below.

• In the first line of your post, your should add your plan title and name.
• Your posting must include recommendations, a requirement plan, a development plan, and a testing plan.  

A walk through the Business section of any bookstore or a quick Internet search on the topic will reveal a seemingly endless supply of writings on leadership. Formal research literature is also teeming with volumes on the subject.

However, your own observation and experiences may suggest these theories are not always so easily found in practice. Not that the potential isn’t there; current evidence suggests that leadership factors such as emotional intelligence and transformational leadership behaviors, for example, can be highly effective for leading nurses and organizations.

Yet, how well are these theories put to practice? In this Discussion, you will examine formal leadership theories. You will compare these theories to behaviors you have observed firsthand and discuss their effectiveness in impacting your organization.

To Prepare:

• Review the Resources and examine the leadership theories and behaviors introduced.
• Identify two to three scholarly resources, in addition to this Module’s readings, that evaluate the impact of leadership behaviors in creating healthy work environments.
• Reflect on the leadership behaviors presented in the three resources that you selected for review.

By Day 3 of Week 4

Post two key insights you had from the scholarly resources you selected. Describe a leader whom you have seen use such behaviors and skills, or a situation where you have seen these behaviors and skills used in practice. Be specific and provide examples. Then, explain to what extent these skills were effective and how their practice impacted the workplace.

By Day 6 of Week 4

Respond to at least two of your colleagues on two different days by explaining how the leadership skills they described may impact your organization or your personal leadership, or by identifying challenges you see in applying the skills described.

Please read the attachment instructions carefully!!!!!

You have had plenty of practice with data analysis in the Discussions and hopefully you have received helpful and encouraging feedback from your colleagues. Now, for the last time in the course, it is time once again to put all of that good practice to use and answer a social research question using categorical statistical tools. As you begin the Assignment, be sure and pay close attention to the assumptions of the test. Specifically, make sure the variables are categorical level variables.

For this Assignment, you will consider three different scenarios. Each of these scenarios includes a research question. You will examine each scenario, choose a categorical data analysis and run a sample test.

To prepare for this Assignment:

• Review Chapters 10 and 11 of the Frankfort-Nachmias & Leon-Guerrero course text and the media program found in this week’s Learning Resources related to bivariate categorical tests.
• Using the SPSS software, open the Afrobarometer dataset found in this week’s Learning Resources.
• Next, review the Chi Square Scenarios found in this week’s Learning Resources and consider each research scenario for this Assignment.
• Based on the dataset you chose and for each research scenario provided, using the SPSS software, choose a categorical data analysis and run a sample test.
• Once you perform your categorical data analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.

For this Assignment:

Write a 1- to 2-paragraph analysis of your categorical data results for each research scenario. If you are using the Afrobarometer Dataset, report the mean of Q1 (Age). In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.

Use proper APA format, citations, and referencing for your analysis, research question, and display of output.

By Day 7

Submit your Assignment: Testing for Bivariate Categorical Analysis.

Within the Discussion Board area, write 600–800 words that respond to the following questions with your thoughts, ideas, and comments. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas.

Your team attends a trade conference on the subject of globalization. They have attended several seminars both advocating and dismissing implementing a global strategy. You return to the office and share some of what you have learned with the team.

“Globalization is a very interesting topic and can get very heated,” you explain. “There are some countries and companies who are fiercely loyal to their homes and would not consider going global. Others see it as a benefit to the company and their customers. Some people here in the states believe that American-made is best because we are contributing to our home country. But, is it? Is it always best to stay domestic? How does this impact pricing? Are you truly helping?”

As your team ponders these questions, you start to think about your position on the topic. Complete the following:

• Are you for or against globalization?
• Is your recommendation for your company to go global? Why or why not?
• How does globalization impact the marketplace as a whole?
• Has your opinion changed from the beginning of the course to now?
