many schemes about block matrix method, mainly focusing on the multiplication.
but it isnt impossible to find a block matrix method for linear algebra.
For parallel solver, it is not just simple blocked matrix. many tricks there.
after all, the setup for ghost node or halo is not trivial.
the solution is , I recommend, you better off use the matured opensource library
instead of starting everything from the scratch. The candidate packages are PETSc, umfpack,
