Main Concepts

:ref:`communication <API_s4u_Comm>`, :ref:`disk usage <API_s4u_Io>`,
and other |API_s4u_Activities|_, so that they get reflected within the
simulator. These activities take place on resources such as |API_s4u_Hosts|_,
-|API_s4u_Links|_ and |API_s4u_Storages|_. SimGrid predicts the time taken by each
+|API_s4u_Links|_ and |API_s4u_Disks|_. SimGrid predicts the time taken by each
activity and orchestrates the actors accordingly, waiting for the
completion of these activities.
The :ref:`simgrid::s4u::this_actor <API_s4u_this_actor>` namespace
provides many helper functions to simplify the code of actors.

Activities
**********
Activities represent the actions that consume a resource, such as a
-:ref:`s4u::Comm <API_s4u_Comm>` that consumes the *transmitting power* of
-:ref:`s4u::Link <API_s4u_Link>` resources.
+:ref:`Comm <API_s4u_Comm>` that consumes the *transmitting power* of
+:ref:`Link <API_s4u_Link>` resources, or an :ref:`Exec <API_s4u_Exec>`
+that consumes the *computing power* of :ref:`Host <API_s4u_Host>` resources.
+See also the :ref:`full API <API_s4u_Activity>` below.

Asynchronous Activities
:cpp:func:`s4u::Mailbox::put_async() <simgrid::s4u::Mailbox::put_async>` and
:cpp:func:`s4u::Mailbox::get_async() <simgrid::s4u::Mailbox::get_async>`.
- :ref:`s4u::IoPtr <API_s4u_Io>` are created with
- :cpp:func:`s4u::Storage::read_async() <simgrid::s4u::Storage::read_async>` and
- :cpp:func:`s4u::Storage::write_async() <simgrid::s4u::Storage::write_async>`.
+ :cpp:func:`s4u::Disk::read_async() <simgrid::s4u::Disk::read_async>` and
+ :cpp:func:`s4u::Disk::write_async() <simgrid::s4u::Disk::write_async>`.
- :ref:`s4u::ExecPtr <API_s4u_Exec>` are created with
:cpp:func:`s4u::Host::exec_async() <simgrid::s4u::Host::exec_async>`.
- In the future, it will become possible to have asynchronous IPC
memory gets properly reclaimed. This call should be at the end of the
actor's function, not in a on_exit callback.
