Week	Topics	Reading
Week 1 9/3	Tuesday Syllabus Introduction to final project Approach Programming Testing ==> paper (see 2011 paper for example). Parallelism: going to the source: Interrupts! 8086 type of interrupts (simplified) Interrupt Vector Interrupt Priority Context Switch Stack and Stack Frame Global and Local Variables What is a process? What is a thread? Thursday Goals of multithreading: Enhanced performance Increased throughput Greater user responsiveness What should we remember 5 years from now? Introduction to a graph we'll use all throughout the semester. The idea of threads Thread 1 ----------------------|====|-------------------------> time Thread 2 ------------|====|-----------------------------------> time Multithreaded programming. Computing Pi Mini Lab 1 Regroup and gather statistics on the different machines in the classroom Introduction to Latex Tutorial #1 on Latex and ShareLatex Latex document template Latex Example: Bib File: Example Bib File for Latex paper (from ACM) Learn how to find BibTex entries. Example: The Unreasonable Effectiveness of Data (go to ACM and click on BibTex link). If you are considering working on an honors thesis, you might want to take a look at this page on writing Honors thesis with Latex. Comments on bimonthly newsletter The format should be similar to the ACM Tech News format. The header should contain a title, your name, the class (CSC352) and the date Each paragraph should have a header with a title, the source of news, the date, and possibly a link to the full article. The paragraph describing a news item should be between 3 to 10 lines, give or take. Write 1 full page to 2 pages, depending on the richness of events in the technology field Feel free to present N-1 topics with just 3 lines, and 1 topic which you highlight with a longer paragraph. Topics: anything related to parallelism: computers, mobile platforms, cloud, companies, new software, new algorithms, conferences, people in the field, etc. Good sources of information to get started: the ACM Tech News Wired magazine The NYT Technology Bits MIT Technology Review The Official Google blog Review: Tom's Hardware Some of the sites listed in blorge.com's top-40 list. Recommendation for news aggregator: Feedly.com Homework: play with Latex. Find or adapt a document template for your needs (minimalist is the name of the game at this point), and start gathering news bits. First newsletter due Thursday Sept. 19th. The ACM Tech News format is a good and simple format to emulate.

Week 4 9/24	Tuesday: Guest Lecture/Informal discussion with by Tim Draper Some questions to start the conversation: How has the cloud infrastructure changed entrepreneurship, if at all? There is a whole ecosystem growing around the cloud services offered by Amazon and the other players: new companies offering services and using Amazon's AWS for example. What are some of the most interesting companies/ideas/technologies emerging that you have discovered or been involved with? There is tremendous worries about the safety and privacy of data in the cloud. Is this an area of growth students should consider? What other area of growth do you see that students should keep in their view-sight? If a graduating major is interested in joining a start-up company, what are the signs she should be looking for before joining such a group? Some students are interested in a management track, starting at a big company and climbing fast. What is your advice for best preparing for this type of career? What is the most exciting development in your eyes happening now with cloud technology? It has been said that the 21st century is the century of the entrepreneur. Do you see this as true? Companies rise and fall. Microsoft was once the place where all our majors wanted to go. The most prestigious company for programmers. Now it's Google, and Facebook. Which company(ies) do you see as potential new meccas for programmers? If somebody were to form a start-up with friends. Say 10 people. Who/What/Where? Who should the people be? What field should they be experts in? Where should the company locate? Review of Homework 1 and its Solution. Understand static variables don't use global random generators! /usr/bin/time multiplies time by the # of cores for threaded applications be sure to understand if you need the same random seed or a different seed in your experiments create a different user on your laptop with no extra applications loaded in the background (e.g. Skype): less stress on the O.S. Thursday Mountain Day!

Week 11 11/12	Tuesday Paper presentation: General-Purpose vs. GPU: Comparisons of Many-Cores on Irregular Workloads, presented by Yoshie Questions about the paper: What kind of paper is this? Broad distribution? Research? Small group? Organization? Abstract? Introduction? Definition of specialized terms? Early enough in the paper? Are the contributions of paper clear? The section on related research sufficient? What is being compared? Similar machines? Hardware? Software? Are authors partial? Do they have a stake? How does the paper advance the state of research? What does it tell us about the way computer systems evolve? Thinking about the project What do we know better about the overall project. What pieces have we looked at? What is it we don't know? Can we turn any of these questions into a project? Thursday A few comments on Manager/Worker paradigm in MPI: not the only one.

Week 12 11/19	Tuesday: 1 month to go (exactly) before the project is due (Dec. 19)! Student-directed work (DT @ INFOCOMP 2013) Finish the MapReduce lab on AWS and make sure you do the Challenge 2 part of the lab. Food for thought: some videos I suggest one of you connects her laptop to the projection system and you all watch these videos together. After each one, discuss it as a group. Take notes and be ready to share your comments during Thursday's class when we resume our regular schedule. The Creators Projects video This video is not necessarily anything that can work for us, but it's just "food for thought." Just a different way an artist has come up to make still pictures interesting to look at. Short, 6 minutes O'Reilly Radar Videos Tim O'Reilly is a visionary who figured out a long time ago that computer technology was an exploding field and he started a very successful line of books to support all new technology projects that were emerging and promising. The books all have animals on them and are uniquely easy to spot. O'Reilly now also has an on-line channel (O'Reilly Radar), and organizes conferences with top researchers and intellectuals in the field of computer science. The first video is with Doug Cutting, one of the creators of Hadoop. He makes some very good points about what Hadoop is, what it is good at, and what it might not be good at (Homework 5 lesson?). After Cutting you can skip the 2nd interview (about video technology) and zip to the 3rd interview with Jeremy Howard, at time-tag 13:47. Then learn about big data and analytics, and what is said of data scientists. About 12 minutes total. Good interview of Tim O'Reilly describing Web 2.0, and his view of a data-driven Internet. </center> </center> Thursday: Tentative guest lecture: Nick Howe on CUDA and GPUs Going over Homework #5
Week 13 11/26	Tuesday: No newsletter due Paper presentation: A View of Cloud Computing presented by Danaë. Instead of a newsletter, you may turn today a draft of an introduction to your final project. If you have too much work this week, you can turn this in on 12/3. Thursday: Thanksgiving Break
Week 14 12/3	Tuesday Paper presentation: The Unreasonable Effectiveness of Data presented by Julia Instead of a newsletter, you need to turn in a draft of an introduction to your final project (unless you submitted it last week). Thursday
Week 15 12/10	Tuesday: Last Day of Class 20-minute presentations of projects. Suggested outline: The context: how your project fits in the overall pictures Has other similar work been done and documented before What you decided to do The challenges The choices The target experiments Preliminary results Expected results Possible directions for continuing research after the project
