The different models rely on a linear inequalities solver to share
the underlying resources. SimGrid allows you to change the solver, but
be cautious, **don't change it unless you are 100% sure**.

- items ``cpu/solver``, ``network/solver``, ``disk/solver`` and ``host/solver``
allow you to change the solver for each model:
Configuring SMPI
----------------
-The SMPI interface provides several specific configuration items.
+The SMPI interface provides several specific configuration items.
These are not easy to see with ``--help-cfg``, since SMPI binaries are usually launched through the ``smiprun`` script.
