Just checking if this has changed at all over the past few years. Is there a way to run MatrixCreator::create_mass_matrix with MPI?
It's running fine for me when I use -np 1 , but -np 2 or more causes a crash. I don't see any way to pass in the locally_owned_dofs, so I'm assuming not, but I thought I'd double check if there's another recommended approach.
