h2. Introduction
The goal of COMP 322 is to introduce you to the fundamentals of parallel programming and parallel algorithms, using a pedagogical approach that exposes you to the intellectual challenges in parallel software without enmeshing you in low-level details of different parallel systems. To that end, the main pre-requisite course requirement is COMP 211 or equivalent. This course should be accessible to anyone familiar with the foundations of sequential algorithms and data structures, and with basic Java programming. COMP 221 is also recommended as a co-requisite.
The pedagogical approach will introduce you to the following foundations of parallel programming:
* Primitive constructs for task creation & termination, collective & point-to-point synchronization, task and data distribution, and data parallelism
* Abstract models of parallel computees and computation graphs
* Parallel algorithms and data structures including lists, strings, trees, graphs, matrices
* Common parallel programming patterns including task parallelism, undirected and directed synchronization, data parallelism, divide-and-conquer parallelism, map-reduce, concurrent event processing including graphical user interfaces.
Laboratory assignments will explore these topics through a simple parallel extension to the Java language called [Habanero-Java|http://habanero.rice.edu/hj] (HJ), developed in the [Habanero Multicore Software Research project|http://habanero.rice.edu] at Rice University. The use of Java will be confined to a subset of the language that should also be accessible to C programmers \--\- no advanced Java features will be used. An abstract performance model for HJ programs will be available to aid you in complexity analysis of parallel programs before you embark on performance evaluations on real parallel machines. We will conclude the course by introducing you to some real-world parallel programming models including the Java Concurrency Utilities, CUDA and Google's MapReduce. The foundations gained in this course will prepare you for advanced courses on Parallel Computing offered at Rice (COMP 422, COMP 522).
Since the aim of the course is for you to gain both theoretical and practical knowledge of the foundations of parallel programming, the weightage for course work will be balanced across four written assignments, three programming assignments, and two exams.
h2. {color:#003366}{*}Textbooks{*}{color}
There are no required textbooks for the class. You will be expected to read each lecture handout before coming to the lecture. We will provide a number of online references in the lecture slides as well.
However, there are two optional textbooks that we will draw from quite heavily. You are encouraged to get copies of either or both books as useful references during and after this course:
* [Java Concurrency in Practice|http://jcip.net/] {color:#515151}by Brian Goetz with Tim Peierls, Joshua Bloch, Joseph Bowbeer, David Holmes and Doug Lea{color}
* [Principles of Parallel Programming|http://www.pearsonhighered.com/educator/academic/product/0,3110,0321487907,00.html] by Calvin Lin & Lawrence Snyder

h2. Grading, Honor Code Policy, Processes and Procedures
{color:#000000}Grading will be based on your performance on homeworks (worth 50%) and exams (20% for first exam, and 30% for the second exam).{color}
{color:#000000}The purpose of the homeworks is to train you to solve problems and to help deepen your understanding of concepts introduced in class. Homeworks and programming assignments are due on the dates and times specified in the course schedule. Please turn in all your homeworks using the CLEAR turn-in system. Homework is worth full credit when turned in on time. A 10% penalty per day will be levied on late homeworks, up to a maximum of 6 days. No submissions will be accepted more than 6 days after the due date.{color}
{color:#000000}You will be expected to follow the Honor Code in all homeworks and exams. All submitted homeworks are expected to be the result of your individual effort. You are free to discuss course material and approaches to problems with your other classmates, the teaching assistants and the professor, but you should never misrepresent someone else’s work as your own. If you use any material from external sources, you must provide proper attribution. Take-home exams, which are pledged under the Honor Code, test your individual understanding and knowledge of the material. Collaboration on exams is strictly forbidden. Finally, it is also your responsibility to protect your homeworks and exams from unauthorized access. {color}
The work you submit for this class is expected to be the result of your own work and that of your homework partner. You are free to discuss course material and approaches to problems with your other classmates, the teaching assistants and the professor, but you should never misrepresent someone else’s work as your own. If you use any material from online sources, you must provide proper attribution (as shown here) in your homework/programming assignment turnins. A tutorial on how and when to cite sources is here. You should explain what value you have added to work taken from online sources. Finally, it is also your responsibility to protect your work from unauthorized access. I will expect you to follow the Honor Code in this course.
{color:#000000}Graded homeworks will be returned to you via email, and exams as marked-up hardcopies. If you believe we have made an error in grading your homework or exam, please bring the matter to our attention within one week.{color}
