=====================
SimGrid was conceived as a tool to study distributed algorithms. Its
-modern :ref:`S4U interface <S4U_doc>` makes it easy to assess Cloud,
-P2P, HPC, IoT, and similar settings.

A typical SimGrid simulation is composed of several |Actors|_, that
execute user-provided functions. The actors have to explicitly use the
