Alexander,
I have written a small feature enhancement that allows MGTransferPrebuilt to
be used with parallel PETSc matrices. If possible I would like to contribute
this change back to the main development branch. I guess that I should submit
a pull request but I made changes that I would lik

Hello everyone!
This is deal.II newsletter #24.
It automatically reports recently merged features and discussions about the

It is setting up the matrices which is the bottleneck, specifically setting
up the off-diagonal blocks of the matrix. For context, with a moderately
sized system of 200,000 dofs, setting up the main NxN sparsity pattern
using DoFTools::make_sparsity_pattern and reinitializing the matrix using
t
That works, thanks!
