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.

Great course. Introduces Parallel Programming in Java in a gentle way.\n\nKudos to Professor Vivek Sarkar for simplifying complex concepts and presenting them in an elegant manner.

Excellent Course.I always wanted a good course on java concurrency and parallel programming.And finish->async, isolated, forAsync constructs are awesome.I have learnt much from this course.

Introduction to theoretical concepts was good, but not very deep. The exercises didn't really contribute much to my understanding of the course material in general.

I liked the course. It introduced some of the concepts in parallel programming very well. I would suggest if it focuses more on Java implementations from the java.util.concurrent package like Countdown Latches and Cyclic Barriers it would be more helpful.

Great Learning and understanding the parallelism concepts in java

-1 star due to the too-easy homework.

I wish the homework can be harder and more challenging.

It was a useful course, but last two homeworks were exactly same as professor explained in demo implementations. I would expect them to take a bit more time and having a variety of easy/difficult tasks in each homework.

This course is a good introduction to parallel programming,

but i noticed a number of shortcomings.

Some themes are not reflected in mini-projects:

- memoization in week 1;

- data flow and pipeline parallelism.

The mini-project for week 3 is too easy.

Some questions in the quiz in week 4 does not match the contents of the course.

This course is quite a shot one. The lectures are condense and programming assignments are purely academic. However I still would suggest to take it if one wants to learn about high level abstraction upon parallel computing in Java.

The exercises are just a little short and I'd like to see, maybe, twice as many quizzes with a better connection to lecture notes, but the lectures are very enlightening, the subject matter is very interesting, and the exercises, though excessively sparse, are helpful.

Great material, well arranged course flow, willing teacher, and nice project snippets. More coding samples and projects could have been included.

Thank you for this course! Really interesting, but lacks the real world examples and has little number of tasks to complete.

Very good and comprehensive video lectures! Sometimes the auto-grader results from Coursera fluctuate from one submission to the other, but overall it was a really interesting course.

The videos were very well done. The exercises were a bit too easy in my opinion. But the exercises did focus on the issue at hand, unlike some other courses that get you stuck on complicated but unrelated issues used only as an example problem.

Provides background material for the course on concurrency in the same specialization. Assignments are trivial.

par Samuele M

Course is interesting, but lacks in contents: just few patterns are explained, and few concepts about parallelism, and there are very little details about further algorithms. Assignments, projects in particular, are quite useless or incredibly easy, or need usage or knowledge of libraries not explained/used in course, and included in "optional readings". Lessons are really clear (bravo! to the Professor), but quite short, since whole course doesn't reach 2 hours of lesson. I definitively think that course can be improved with more contents.

good coverage of basics.. would have been great if there were few more coding practice papers.

Lectures were adequate to understand the basic concepts/syntax and where and how to use them, but did not go deep into the underlying working.

The mini projects weren't that helpful since the assignments were the same examples as shown in the lecture, and the TODOs were generally just a couple of lines, leaving us with with little to do.

By the end of the course, I got to know the different Java util classes to use to for parallelism.

Although much of the content was informative and well taught, half of the programming assignments were either rudimentary or completely unnecessary since the answer was given in the provided file. On the whole, this course was just too short and too easy.

Good overview, but less details

Subject is very interesting. However course is sometimes unclear, and assignments sometimes are related with the specific library developed by the professor, not with the generic Java implementations. However I'm happy to have completed this course, i've learned a lot.

I would prefer see examples based on standard Java code, not in a library developed for some small group.
