    [el2p] parallelize the el2p model · 8c450823
    Bernd Flemisch authored
    So far, the el2p model did not run in parallel, since our parallel
    solvers assume a certain ordering of the degrees of freedom. This patch
    mainly introduces an AMG backend that is tailored to the el2p model. It
    simply reorders the linear system by copying from the original system,
    passes the reordered system to the original AMG backend, and
    reorders/copies the result back. This could be achieved more
    efficiently and with less memory usage by already reordering the dofs
    inside the el2p model or by adapting the AMG backend. Since the
    performance impact appears to be minimal, we decided to keep the current
    simple solution and try a better one once we need it.
