Dear all,
I hope you are well.

I know that P4est as a partitioner has limitations compared to other 
approaches like Metis or Scotch. However, I was wondering if there was 
anyway to penalize the partitioner in order to generate the smaller valence 
that is possible? Sometimes we end up with interfaces between processors 
that are substantially big (or islands of a few cells). The issue is that 
for our particle code, this generates a ton of Ghost particles and these 
particles generate additional cost (collisions become significantly more 
expensive to calculate because we cannot apply newton's third law for a 
collision. The calculation becomes essentially duplicated). 

I was wondering if there was any ways to "force" or ensure that the 
interfaces between subdomains remained relatively well-posed?

Thank you very much!
Bruno
