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.

This course has a good combination of clear lectures, helpful textual summaries, reasonable/helpful quizes, and decent weekly projects. If anything, I wish that the projects were a little more challenging. The first three were fairly easy and I wish that we had been required to implement them from scratch rather than having the starting version which required only minor modifications. The last project assignment was a little tricky because the lectures didn't cover all the details of phasers in sufficient detail, so studying additional documentation was required. Overall, I learned a lot and it was time well spent.

Although this was a very excellent course to understand various API's and methods that are exposed by Java SDK's (RecursiveTasks, Fork/Join Framework etc) and touched on very important multi-core parallelism aspects, I was left wanting for more fundamental explanations regarding how parallelism works under the hood (How the thread works, how the signalling between barrier synchronisation happens etc). Thanks, none the less. Looking forward to next course.

Excellent lectures and provides good understanding of some theory behind Parallel Programming. The professor is a good lecturer and has a great format. Some assignments are very difficult due to the confusion between lecture notes which have errors and differences between the lecture and the notes. But well worth taking the course and understanding how to take advantage of multi-core processing.

Having come from Python world, i have learned valuable concepts in parallel programming and related Java APIs, surely the APIs are much more elegant and powerful in Java. i was disappointed by Week's 3 and 4's assignment task, they were too easy, nevertheless learned a great lot of information. Excellent course for someone who is looking to get into parallel programming!

Learnt a lot about parallel programming and the facilities offered in Java for the same. The best part is the videos are short and nice. However, I'm echoing some of the common sentiment, that the assignments (barring assignment 2) are too trivial, and sometimes are not clear what to do. They can be surely improved, so that students can deepen their understanding.

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.

Tasks are too simple. All the information isn't covered in depth, so consider this course as a sort of introduction to the theory of parallel programming as well as many important Java language features. It gives you a basic idea and points you to the right direction in case you're interested in this complex topic.

This course is a very nice introduction to parallel programming in Java. It highlights the key libraries to explores for production use. On thing I didn't like is that the programming assignments are a copy paste of the demonstration videos in the course. All in all I enjoyed taking this course!
