Parallel Programming in Java

It’s a great course, you learn the fundamentals to keep going and challenge your task at work to improve the performance. I don’t find that good that sometimes we have to use the API’s provided by the University and not Java libraries.

The course is good!

The fundamental core concepts are lucidly setforth by the teacher.

Very informative course.

I liked the course material and the relevant assignments and projects. It is of right difficulty level: gives you knowledge and makes you comfortable with the concepts and tools without making you slog for weeks. I feel students will be able to retain the gained knowledge longer than traditional classes.

The concepts like thinking about work,span,cp.amhdals law very very helpful. Although i believe there should be more examples wit code as in quiz.

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.

Thank you for making taking the time to prepare this and making it available online on Coursera. Cheers!

Excellent lecture videos. Excellent written summaries.

Great introduction to parallel programming in Java. Clear and well thought content. Quite challenging quizzes.

Good course. Slightly basic, but explanation is clear and good.

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.

Awesome course. I did the whole specialization, which I can recommend, from parallel to distributed. Vivek is an inspiring guide with a very natural way of presenting. These can be quite complicated topics and though I feel like I have a good (initial) grasp of them now, they certainly ask for further investigation and practice.

I enrolled in this specific course (not in the whole specialization). Later It turned out that you are not allowed to submit code if you have an unpaid subscription. Fine, I decided to pay for it. After all, someone invested his time in creating the course. Then, for some reason, I have got a subscription for the whole program, not a single course. I did not realize that and got charged the second time after the first month past. But okay, probably I did not understand the whole procedure around it. BUT… The amount of information is very small. For 42 Euro you get few lectures and few quite basic exercises. In most of the tasks you need o write only a couple of lines of code. The evaluation is not reliable. You can do your task right way, but it will not pass test from the first time and you are not sure if your are doing something wrong or what is the reason of the failure. Then you just resubmit the same code and after second, third or fourth time it suddenly works. I can understand that in concurrent environment sometimes it is hard to achieve stable performance. All together this leads to a bad experience. It is not the quality I’ve got used to when watching other courses here. Not worth its money. It is better to buy a book or the same amount.

I spent 6 days on this course, and I feel it is not worth the time. One of the problems is that the lectures are overly basic, and the mini projects are not challenging, at least not in a helpful way (quizzes are sometimes challenging due to some concepts not covered in the lectures at all). I guess the instructor did not really spent much time preparing the materials and assignments.

Would like more assignments and examples.

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

Clear instruction and concepts provided with this 4 weeks long course.

Not sure it deserves the money, YouTube has more content, but I love the prof dress

great course, learn a lot!

Ok

Really didactic!

I liked very much the material support. I found fascinating the framework PCD. Congrats

Nice course

Interesting, but the presentations, support materials and programming exercises have some issues. I’m not fond of the usage of pseudo code, when this is a Java course. I want the example to use existing Java libraries, preferably from the standard Java JDK. For the exercises, in addition to unit tests that test the performance of the code, it would be valuable to have tests that run quickly, and test that the code computes correctly. For the Week 4, the only provided test took some 9 minutes to run. A unit test should take a second at most.
