That would be very kind. If you have other (even unfinished) documentation on this topic that you are willing to share, it is very welcome. I am more interested in the C++ interface than C. Your 2009 paper is helpful to understand the Sieve concepts, but working with the implementation in PETSc is a different story. However, I think all the replies I got so far will allow me to get started now.


Thanks
