8. Overview Administrative stuff Classes: –Topics –Paper readings and reviews –Presentations/debating –Research ideas Projects: –Topics

9. I tried to pick interesting papers (breadth vs. depth), a combination of old and new papers –Cloud applications –Data-center architectures –Cloud usage –TCP incast problem –Cloud security and privacy –Software-defined networking –Energy issues in cloud computing Course Topics

10. Reading papers Why read? Decide what to read Reading for breadth: build a framework Reading in depth: Challenge what you read –if you will lead a debate

11. Reviews Should… –Point out the paper's contributions, strengths as well as weaknesses. Think in terms of what makes good research? What qualities make a good paper? What are the potential future impacts of the work? Note that there is no right or wrong answer to these questions A review's quality will mainly depend on its thoughtfulness. Restating the abstract/conclusion of the paper will not earn a top grade.

12. Writing Reviews (2) Write a very brief summary of each paper, to be emailed to me before the class (.txt please) Summary should include: –Paper title and its author(s) –A short paragraph summary (what is this paper about?) –A paragraph of the most significant new insight(s) you took away from the paper (what is good? what is the contribution?) –A paragraph of the one or two most significant flaw(s) of the paper (what is bad?) –Explain what reference would you read next and why –Give a grade to the paper (1-5)

13. Overview Administrative stuff Classes: –Topics –Paper readings and reviews –Presentations/debating –Research idea Projects: –Topics

14. Defense (1) 30 minutes; should present as if it were his/her own The point is to make a compelling case why the contribution is significant. the context of the contribution, prior work, –If an older paper: how the work has influenced the research community or industry's directions (impact) –If newer paper: arguments for the potential impact

15. Defense (2) –should go well beyond a paper "summary“ –The defense should not critique the work other than to try to pre-empt attacks from the offense (e.g., by explicitly limiting the scope of the contribution). –The defense should also try to look up related work to support their case

16. Offense (1) 20 minutes; Should critique the work, and make a case for –missing links, unaddressed issues, lack of impact, inappropriateness of the problem formulation, etc. The more insightful and less obvious the criticisms the better While the offense should prepare remarks in advance, they should also react to the points made by the defense. Hint: The offense should also try to look up related work to support their case

17. Offense (2) The defense and offense will be allowed follow up arguments, The class will question either side either for clarifications or to add to the discussions and controversy and make their own points on either side. Use Powerpoint (feel free to use existing presentations from the Web)

18. Overview Administrative stuff Classes: –Topics –Paper readings and reviews –Presentations/debating –Research ideas Projects: –Topics

19. Research Idea (1) At the end of semester, you may hand in a research proposal Up to 3 pages including references Something that nobody else did before –What would you do? –How would you do it?

20. Research idea (2) Writing the research-idea documents: –What is the main idea? –Why is it important/interesting? –What is the related work? –What would you actually do? How would you execute the idea: –Modeling, simulations, experiments? –What is the expected outcome?

23. Timetable Week 2 (Monday 4/7) Find a partner, choose a topic for your project, and meet with the instructor (or get an agreement via e-mail). Week 3 (Monday 4/14) Write an introduction describing the problem and how you plan to approach it (what will you actually do?). Include motivation (why does the problem matter?) and related work (what have others already done about it?). 3 pages total. Week 6 (Monday 5/5) Update your paper to include your preliminary results. 5 pages total. Midterm presentations. Week 10 (Wednesday 5/28): Final presentations by all groups. Week 11 (Friday 6/6) Turn in your completed paper. 10 pages total.
