Discover SMPI

-SimGrid can not only :ref:`simulate algorithms <usecase_simalgo>`, but
+SimGrid can not only :ref:`simulate algorithms <Tutorial_Algorithms>`, but
it can also be used to execute real MPI applications on top of
virtual, simulated platforms with the SMPI module. Even complex
C/C++/F77/F90 applications should run out of the box in this
environment. In fact, almost all proxy apps provided by the `ExaScale
Project <https://proxyapps.exascaleproject.org/>`_ only require minor
modifications to `run on top of SMPI

This setting permits to debug your MPI applications in a perfectly
reproducible setup, with no Heisenbugs. Enjoy the full Clairevoyance
