I'm happy to help as mentor but not sure what a good project would be that I can really help with - neither the ParallelIS nor UG is anything I know much about. I attached a list I compiled for an application in 2022 - some of this is already taken care of.
The LFE stuff is perhaps the most interesting idea so I reiterate that and the following fit together to some extend:</div>

2: Reimplementing the 'generic lfe' - I was thinking about combining that with some code generation so that the local degrees of freedom are prescribed in some python script (perhaps using sympy or UFL) and then the corresponding LFE is generated similar to
what is done now on the C++ side. Also <a href="https://github.com/mscroggs/symfem">
https://github.com/mscroggs/symfem</a> could be a starting point.</div>

4: there has been some new work on using vtk to visualize higher order elements. Would be nice to have something like that - I think that is not really in dune-vtk but I might be wrong.</div>

<div class="PlainText">Dear all,<br>
<br>
thanks for your plans to apply to Google summer of code!<br>
<br>
We would be interested (and willing to mentor) a project on rewritting <br>
the ParallelIndexSet (in dune-common) infrastructure with the following <br>
improvements:<br>
<br>
- use containers/algorithms from standard library for implementation<br>
- asynchronous communication allowing to do something while communicating<br>
- data handles expose source/destination rank in scatter/gather<br>
- allow send/receive to the same container<br>
<br>
Any interest in that?<br>
<br>
Best,<br>
<br>
Peter<br>
