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.

The concepts are explained well. Quizzes and mini project has good details to understand the concept better.

Could have had more demonstrations, or even examples for reference. Overall, it was a very good course.

More details on concurrency would be a huge benefit to course and students (even as optional material)

Good course that gave you a good overview. The code assignments code have been a little more advanced.

Simple delivery, very manageable work load, and still something tangible to take away from the course.

It was useful and interesting course, however, I'd like to see more complicated practical tasks

-1 star due to the too-easy homework.

I wish the homework can be harder and more challenging.

it'll be perfect if mini projects can deeper test what we've learned in the class.

While i've definitely learned something new, there are some frustration points:

> Material presentation and abuse of pseudo code. Some concepts presented at very high abstraction level without going into details of implementation. Part of course relay heavily on custom parallel programming library, writing in java while other parts are given in built-in Java framework. In lecture summary code is presented as pseudo code, so there are not way to run and see that it does.

> Length of the course. Most of weeks has about 30 minutes of videos in total.

> Issues with grader. Grader is not reliable, you can find that same code sent twice will result in fail and pass. Also, when running test locally, it may fail, while passing when send for real (in my case it was because test code from assignment incorrectly gave number of processes when hyper-threading is enabled)

> Easy exercises. Apart from grader issues, assignment itself do not gave any challenge. Assignment of one week can be passed by just changing signature of method to right one (literally just few characters change)
