I would suggest reading through this first: [Parallel Computations with Dolfinx using MPI — MPI tutorial](https://scientificcomputing.github.io/mpi-tutorial/notebooks/dolfinx_MPI_tutorial.html) then try to refine your question a bit, as I do not have time to repeat all the various posts I have on the forum about this, including: [What's the best way to assemble a form? - #3 by dokken](https://fenicsproject.discourse.group/t/whats-the-best-way-to-assemble-a-form/8434/3), [DofMap and ghost values - #3 by dokken](https://fenicsproject.discourse.group/t/dofmap-and-ghost-values/11760/3) and many others
