Student project: look into OpenACC

[stiber]

What kind of issue is this?

• [ ] Bug report
• [ ] Feature request
• [ ] Question not answered in documentation
• [ ] Cleanup needed
• [X] Interesting question

The question is whether OpenACC can give us the performance we need. Would be interesting to experiment by taking the CPU-only code and moving one or more operations now done with CUDA kernels into OpenACC implementations to compare performance. See https://groups.google.com/d/msg/uwb-braingrid/pWeIUr-CgyE/tXbSG3wdAAAJ for a link to an OpenACC tutorial.

What is affected by this?

How do we replicate the issue/how would it work?

Expected behavior (i.e. solution or outline of what it would look like)
