課程概述

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.

Thanks for the course materials! I'm getting a lot of new knowledges from the course for cs fundamentals. I'd like to suggest to have more concrete examples to explain many concepts like SPAN, signal and put, etc.

Great introduction to parallel programming. Lectures were clear, summaries were helpful, quizzes were not trivial, discussion forum is good, but the assignments' grading system could be improved.

I found the explanation of how to precisely code phasors lacking as the Thread stuff was already provided in sample code and never explained. Quite satisfied with the rest of the course though.

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.

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.

Very useful course about parallel programming theory and practice.

Could be less examples with custom libraries instead of standard java features looking to practical usage at work.

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.

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.

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

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.

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.

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.

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.

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

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

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

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

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.
