This course needs to do some serious improvement work on the auto-grader and the exact instructions for what the auto-grader is expecting. I spent hours on incredibly stupid issues, like the Week 4 assignment needs a blank row on line four for the auto-grader to accept it. The discussion forums are full of confused students who know the material but can't get the auto-grader to pass, due to vague instructions. The video content is good and I enjoyed the teacher, but this course should really be removed from Coursera until the technical issues are fixed.

Amazing contents of the videos. The assignments are absolute disaster-it's such a pity.

There were simply too many technical issues with the jupyter notebook assignments. One should not have to modify hidden .config.ini files etc.

Many of the concepts covered by the lecture are vague and you'll need to refer to extra resources to understand what it's all about. Not to mention that the homework environments are broken and descriptions are misleading.

While teaching material is progressive and suitable for an introductory course, a large part of the programming assignments have been poorly written or deliver incomplete instructions. This, together with the very scarce value of the automated grading tool - replies are hardly useable - makes it often impossible to understand the errors and causes a substantial waste of time, not proportionate to the complexity of the assignment itself. Moreover, the lack of replies from supervisors or instructors to the numerous queries posted by students seems to show that this course is running unattended. Coursera should seriously consider removing it from its portfolio, considering the very low return on investment for students.

Good course. The lectures and interesting and the mini-cluster provides an excellent practice environment. The only reason I didn't give it five stars is because some of the assignment prompts are ambiguous and the autograder does not provide any helpful feedback on what you missed. I spent 3+ weeks trying to finish one assignment that should have taken a few hours. But the course is otherwise worth your while if you want a solid introduction to HPC.

Do NOT waste your time taking this course. While the videos give you a good understanding, the submission components are broken. Additionally the first "week" is only about Linux commands and not related to HPC. This course needs a significant overhaul.

A very good and interesting HPC introduction course!
Good for an introduction of HPC concepts, but some lectures leave a lot to be desired. In some videos the instructor is just reading out what is written on the slide, without expanding or providing more context. Instructions for some of the assignments were confusing, the submission process was buggy. Thanks to all the students that contributed in the discussion forums where pointers like "add blank line at the end", "edit .config.ini file" etc. proved very valuable. I expected more for a course I paid $ to attend.

Great basic overview, I finally understand what IT is talking about in meetings. I also appreciate the overview of parallel computing and how to structure programs for best advantage. However, the coursera lab environment is buggy. So, I spent more time struggling to just submit the assignments, instead of understanding the assignment.

this course was good except that the instructions for some of the assignments are super unclear, the discussion forum is full of people who have wasted hours on tiny little things that could only be found out y trial and error as the required solution for the grading bot doesnt match the assignment instructions. The course authors did not reply within the 3 months it took me to eventually pass all the assignments. so if you just wanna learn this course is good, but if you actually want the certificate and not be annoyed stay away! :)

In the video lectures, the instructor only reads out loud the text on the slides. However, the lectures are not so bad, although more detailed information would be very helpful. The quizzes are very easy (too easy?) and each quiz consists of ~5 questions. The programming assignments are also very, very basic. The actual task is to figure out what should be done and what the correct input format is. I spend >90% of my time reading compaints in the discussion threads hoping for clarification and only <10% of my time coding. Even questions that have been asked 3 months ago remained unanswered by the instructors who seem to be absent from the course. Luckily, some couse participants figured out what the instructors expect as a solution and shared this information.
In conclusion, this was the worst coursera course I have ever taken and I strongly suggest coursera to take action (either take this course offline or make sure it is improved).
