10 /** @defgroup plugin_operation plugin_operation Plugin Operation
14 This is the operation plugin, enabling management of Operations.
15 To activate this plugin, first call :cpp:func:`Operation::init`.
17 Operations are designed to represent workflows, i.e, graphs of Operations.
18 Operations can only be instancied using either
19 :cpp:func:`simgrid::plugins::ExecOp::init` or :cpp:func:`simgrid::plugins::CommOp::init`
20 An ExecOp is an Execution Operation. Its underlying Activity is an :ref:`Exec <API_s4u_Exec>`.
21 A CommOp is a Communication Operation. Its underlying Activity is a :ref:`Comm <API_s4u_Comm>`.
