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.

Kudos to Professor Vivek Sarkar for simplifying complex concepts and presenting them in an elegant manner.

Good introduction to the concepts of parallel programming, the programming assignments were a bit easy though and could be made harder to improve the learning experience.

創建者 Vaibhav G


Very well structured, taught and paced course, I only wish it had a passing project which would have given us more hands on practice and insights to parallel programming.

創建者 Sebastiaan V


The information found in this course is great. The first and second mini projects were of average difficulty, but the third and fourth mini projects were too trivial.

創建者 Naveen K G


Explanation of theory was best. But Assignments lacked clarity. For example, we might expect little more clarification about threads In order to use them effectively

創建者 Aykut B


Instructor is awesome. However instead of sharing ready libraries for parallelism (like forall loop) in section 3, native codes should be used for forall loops etc.

創建者 Sarvasva R


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.

創建者 Yasmin E


This course explain the concepts in a great way but the exercises

needs to be more rich with problems to enhance our understanding to the concepts.

創建者 Thatiana F


A great course, but I think it would be even better if only the structures from Java 8 were used, and not the functons build by the Rice University.

創建者 Akshat A


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

創建者 Felix C


T​he last split average array example can have more graphic to illustrate for ease to understand the problem and solution for the last project.

創建者 Umrao S R


Very good to learn parallel programming in java. excellent to teach in simple way with good example and current scope touching description.

創建者 Shady I


The courses covers broadly the new synchronization primitives in Java8. It is very clear and demonstrative. It is very shallow though.

創建者 Vitalii D


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

創建者 Nanditha K R


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

創建者 Abir M


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

創建者 Marcin K


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

創建者 Johannes D


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

創建者 Arun N


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

創建者 Ivan K


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

創建者 Xiao X


-1 star due to the too-easy homework.

I wish the homework can be harder and more challenging.

創建者 Wang S


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

創建者 Noam Y


Great material. Interesting lectures. The tasks are not comprehensive enough.

創建者 Isaac A


Enjoyed this course a lot! Wished the projects were a little more substantial

創建者 prabhakar k


thanks to give a simple way to solve parallel programming

創建者 Prabhakar k


i learn new way to do parallel programming in java.thanks to coursera
