Über den Kurs

This course teaches learners (industry professionals and students) the fundamental concepts of parallel programming in the context of Java 8. Parallel programming enables developers to use multicore computers to make their applications run faster by using multiple processors at the same time. By the end of this course, you will learn how to use popular parallel Java frameworks (such as ForkJoin, Stream, and Phaser) to write parallel programs for a wide range of multicore platforms including servers, desktops, or mobile devices, while also learning about their theoretical foundations including computation graphs, ideal parallelism, parallel speedup, Amdahl's Law, data races, and determinism. Why take this course? • All computers are multicore computers, so it is important for you to learn how to extend your knowledge of sequential Java programming to multicore parallelism. • Java 7 and Java 8 have introduced new frameworks for parallelism (ForkJoin, Stream) that have significantly changed the paradigms for parallel programming since the early days of Java. • Each of the four modules in the course includes an assigned mini-project that will provide you with the necessary hands-on experience to use the concepts learned in the course on your own, after the course ends. • During the course, you will have online access to the instructor and the mentors to get individualized answers to your questions posted on forums. The desired learning outcomes of this course are as follows: • Theory of parallelism: computation graphs, work, span, ideal parallelism, parallel speedup, Amdahl's Law, data races, and determinism • Task parallelism using Java’s ForkJoin framework • Functional parallelism using Java’s Future and Stream frameworks • Loop-level parallelism with extensions for barriers and iteration grouping (chunking) • Dataflow parallelism using the Phaser framework and data-driven tasks Mastery of these concepts will enable you to immediately apply them in the context of multicore Java programs, and will also provide the foundation for mastering other parallel programming systems that you may encounter in the future (e.g., C++11, OpenMP, .Net Task Parallel Library)....

This is a great course in parallel programming. The videos were very clear, summaries reinforced the video material and the programming projects and quizzes were challenging but not overwhelming.

The combination of quiz and programming assignment helps understanding the course in a quite nice way. I will finish up the other two courses for sure.

This was a very well laid out, useful, and interesting course. I have done a few of them and this was one of the better ones by far. Clearly communicated and short lectures. Assignments that are actually useful and focus on what you learn. Course doesn't require a huge time sink so good for professionals.

The video lessons are short and well made with practical summaries. Parallelism is a must for every serious software engineer just as being good with algorithms and data structures. Re-watch the videos and summaries to help you do the mini-projects.

Concise, well structured and effective. I now know the basics of ForkJoinPool, barriers, split-phase barriers and promises. Also the analysis of computation graphs really solidified my understanding of the relationship between parallelism and speedup over sequential equivalents.

Dear Coursera and Rice University team, thank you for this course.

Being a PhD student at Nazarbayev University (Astana, Kazakhstan) at Department of Electrical and Computer Engineering I found answers for lots of my questions about parallel programming and also new direction that I should move on.

Excellent introduction to parallel programming in Java. Professor Sarkar is very clear and detailed in his lectures. The quizzes are challenging but not overly difficult. The projects are very straightforward and the video demonstrations are very helpful. Professor Sarkar and the teaching assistants were very active in the forum, helping to answer questions, clarifying concepts, and resolving issues.

One area for improvement is the automated testing grader of the projects. The projects are graded on percentage speedup of your parallelized code, but sometimes they would pass locally while not pass on the testing server. Then I just had to keep submitting the same code over and over again until the tests finally all pass. It's nice the number of times you can submit is unlimited, but having to submit the same code just to pass a certain speedup threshold is not the best use of time.

Overall, I learned a great deal, and appreciate all of the hard work that went behind putting together a course like this. Highly recommended!
