I was tearing apart between 4 and 5. Still I liked the course very much asit provides great insight into parallel programming and algorithms. The problem are the assignments that feels a little unbalanced: week3 is just a few lines of code and feels more like quiz while others are quite challenging, but still it seems that a lot of work in assignments is already done by the teaching stuff.

The assignments are tougher than expected. I was stuck on Barnes-Hut Simulation and Reductions assignment for more than weeks individually. The explanations are clear, but I wish the week 4 is explained with more clarity. It felt we just rushed into ConcTrees without enough context, and it would better to spend more time on the ConcTree topics and combiners.

Many thanks Viktor and Aleksandar! A very interesting course which gave me a good appreciation of parallel programming in Scala, and helped me consolidate what I had learned in the previous 2 courses with Martin.

The exercises were just the right level of challenge, and demonstrated well the lecture content.

I like the course. I learned some nice ideas for parallel computations, not just Scala specific API.

To polish: sometime lectures and tasks contain many complicated but not significant details. And some important ideas are not emphasized. I had to filter the content carefully.

A very good course which teaches the techniques of Parallel Programming. Anyone wishing to upgrade their knowledge about Parallel Programming, should take this course. The principles are applicable universally, so you can take back the learnings and apply them in your work!

The explanations were accompanied by a level of mathematical rigor which helped clarify the material. I have used parallel machines pretty extensively and I was impressed at how much of this content was new to me. I found the assignments enjoyable.

Unbelievable. This course is a must for those who are looking to work in depth with data parallel intensive applications like Spark and want to understand the mathematics underlying the parallel computing. Thank you very much Viktor and Aleksandar!

Nice course. Very interesting subjects, but have some cons. One is significant usage of imperative programming, also assignment`s difficulty level like a roller-coaster. Some was so easy and some was hard. Anyway, five stars for galaxy! :-)

The course will introduce some topics on parallel programming and Scala. The lectures were complete and well explained. The assignments were a little difficult, specially the last one, but I managed to succeed after a few attempts.

Quality of course material is great, the way of presenting material is also great. For those who liked first course by Martin Odersky I highly recommend to do this one. I had a real pleasure watching lectures and doing assignments.

The topic is well explained in the videos and the assignments are challenging and fun. I really enjoyed how they (the assignments) are usually put in a context, e.g. they are part of some project and you can see some outcome.

This is very interesting course that contains a lot of useful information related to parallel programming. Assignments are challenging enough and it is also interesting to tweak some code in assignments even after submitting.

Great course with challenging concepts to learn !

You'll study all fundamental ideas behind parallelism in Scala.

As a down sides, it's feels really short - only 4 weeks and sometimes instructors do not dive deep into details.

This course shows different techniques for parallel algorithm and is quite advanced. It succeeds to be deep yet understandable, challenging yet achievable. All in all it is very well taught with very interesting assignments.

The 3rd part in the set of scala specialization courses falls into place. This course is an introduction to the challenges of big data sets and the parallel computing solutions available to tackle it.

An excellent course.

Presents Scala's parallel collections, and how they work under the hood. The prefix-sum algorithm is quite mind-blowing, and so are Conc-Trees. The algorithms are presented with plenty of detail, step by step, I enjoyed it!

This course is a gem. The instructors' knowledge is of the highest quality, the contents are of the highest quality and the programming assignments are of the highest quality. All in all, this course is of Rolex quality.

The course is fairly advanced and you would need to review the materials many times to understand the concept. The assignments are definitely fun and not as straightforward as other courses.

Superb study material. Learnt a lot during this course. I am not much into mathematical stuff, but got a hang of how to break problems and improve efficiency through parallelism.

excellent course, a good way to showcase how scala is well suited to patallel programming.

The course itself is very practical and the instructors are very knowledgeable

A worthwhile course. I enjoyed the lectures a lot. Really good grounding on principles which can be applied in other languages/platforms in addition to Scala.

Very good introduction to the topic. Examples and programming exercises were very good, although last assignment was visibly less polished than earlier ones.

This course introduce me to a new world of parallel programming! Must learn for whoever that want to expand the skill set of programming to the new level.

Very deep. I learned a lot of useful techniques.

But I know it will take me many years before I can say I have mastered subject touched in this course.

I learned a lot about parallel processing algorithms, way more than I expected. Even after spending over 10 years programming parallel data processing.
