À propos du cours

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.

very useful concept such as async and future

this course help me understanding parallel programming in Java, I download language X10

please accept my gratitude. the ability to disassemble on the fingers difficult problem is the ability of the truly talented teachers

An excellent course. Thank you, Dr. Sarkar!

During my internship, when I was taking this course, coincidentally, I got an opportunity to use Async tasks , get() etc. Was very happy when I could practically apply the concepts that I learnt during the course.

The course is very well organized and teaches up-to-date techniques for Java parallelization. The material that is covered in this course can be used immediately for Java programmers. The instructor organized the videos so that each video is short and covers one point. His examples show the value of what is being taught and how to apply what is being taught. Every video also comes with a summary of "this is what you should have learned from this video". If you missed any details or didn't understand it, the video summary was very helpful for me. I highly recommend this course for an introduction to parallel programming.

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.

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.

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!

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.
