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.

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)

Too much abstract pseudocode for a Java course. In the third test, I had implemented my own solution because no documentation given for that "pcdp framework", also, my implementation run faster, so I have some doubts about that "framework".
The grader is not accurate, I spent some hours trying to find the way to improve the code in the last miniproject because the one I uploaded failed the 4 cores test, but I uploaded the same again and passed the test...
I suggest to improve examples about Phasers, maybe it would be better to introduce low complexity problems in the examples and a step by step explanation on how it works and... where did the threads came from? They never explain threads in this course.
Definitively, this course can't be called a "specialization" but it is a good course for starters.

Course is interesting, but lacks in contents: just few patterns are explained, and few concepts about parallelism, and there are very little details about further algorithms. Assignments, projects in particular, are quite useless or incredibly easy, or need usage or knowledge of libraries not explained/used in course, and included in "optional readings". Lessons are really clear (bravo! to the Professor), but quite short, since whole course doesn't reach 2 hours of lesson. I definitively think that course can be improved with more contents.

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.

Lectures were adequate to understand the basic concepts/syntax and where and how to use them, but did not go deep into the underlying working.
The mini projects weren't that helpful since the assignments were the same examples as shown in the lecture, and the TODOs were generally just a couple of lines, leaving us with with little to do.
By the end of the course, I got to know the different Java util classes to use to for parallelism.

Helpful course but could be much improved by a bit longer lectures and programming exercises covering more Java material, avoiding mixing in so much on proprietary library concepts and focusing on standard Java parallel programming concepts instead as well as making source code demonstrations in a bit larger font to be able to view on a phone
