10. We used python and the atomic simulation environment (ase) during the computer exercises. What is your opinion regarding the use of python and ase?

13 svarande

Not good»1 7%
It was ok»5 38%
Very good»7 53%

Genomsnitt: 2.46

- The idea was good and it was fun to get practical results. However the more or less complete lack of documentation of ase makes going back into it and doing ones own thing very daunting. We were far to dependant on pre written code and had to use trial and error to understanding how things worked behind the scenes. The pre written code was also clumsy and unintuitive in many cases and could do with a work through. » (Not good)
- Cool simulations, but not so much a deep understanding as in the coding exercises.» (It was ok)
- there should be more comments on what python really does (e.g. when there are default values that were not displayed in the code)» (It was ok)
- Many functions felt lika black boxes, which reduces the understanding of the theory.» (It was ok)
- great guidance by the teachers» (Very good)
- It may be a good idea to include a short python tutorial or links to a python tutorial in the first exercise.» (Very good)

13 svarande

Not good»1 7%
It was ok»4 30%
Very good»8 61%

Genomsnitt: 2.53

- I was almost never qued» (It was ok)
- sometimes it was just faster to do the calculation without queuing (directly on the pc)» (It was ok)
- By and large it was very simple. There was never any real queue time and so forth. It would have been nice if there had been a better editor on beda, or dropbox to sync files and work somewhere else. but generally it was not a big problem.» (Very good)
- If you plan your time, queing is not an issue.» (Very good)

Fair»0 0%
Adequate»1 7%
Good»6 46%
Excellent»6 46%

Genomsnitt: 4.38

- It is a good course, but because so much focus of the exercises was on dacapo and ase which I didn"t feel was that useful I felt it was somewhat lacking. » (Adequate)

29. What should definitely be preserved to next year?

- great guidance by the teachers»
- I really liked the computer exercises and to see what could be done with the theory. »
- computer exercises about silicon and helium, since they help you better understand the lecture materials. Also the questions to answer during lectures, they force you to think and be alert at lectures.»
- The examination form.»
- MATLAB exercises.»
- The MATLAB excercises. They were good for understanding the theory. The second hand-in is also great as one has more motivation to process the feedback from the first hand-in.»
- the exercises are a good practice, one really gets some insight into how dft is done on a simple level. the lectures are good and encourage to try something yourself»
- The two part deadline system, by "forcing" people to go back to an exercise you increase the learning.»

30. What should definitely be changed to next year?

- I think it would be nice to see some more concrete examples of impementation of different methods during the lectures.»
- It is hard to see the connection between beda exercises and lectures. Maybe add some lectures that connect the theory leared to methods/functions that exist in Siesta/Dacapo code.»
- If there is a feasable alternative to ase that would be good. But I do not know what that would be, perhaps smaller exercises (or one less) where students have to find their own way more. This of course is far easier if there is proper documentation.»
- I can"t think of anything.»
- the exercises should be prepared better, less coding errors, better general setup and formulation of the task»
- Do not really know anything that would be changed. »

31. Additional comments

- The computer exercises did not give a very deep understanding of how the models worked, it was more about understanding the result from a physical point of view (which was really intresting) and getting the code right.»
