-@subsubsection pf_tag_host <host>
-
-An host is the computing resource on which an actor can execute.
-
-Attribute | Values | Description
------------------ | -------------------------------------- | -----------
-id | String (mandatory) | The identifier of the host. facilitates referring to this AS.
-speed | double (mandatory) | Computational power of every core of this host in FLOPS (must be positive)
-core | int (defaults to 1) | Number of cores (see @ref howto_multicore)
-availability_file | File name (optional) | (Relative or absolute) filename to use as input; must contain availability traces for this host. The syntax of this file is defined below.
-state_file | File name (optional) | File to use as a state profile (see @ref howto_churn)
-coordinates | String (mandatory when using Vivaldi routing) | The coordinates of this host (see @ref pf_P2P_tags).
-pstate | Double (Defaults to 0) | FIXME: Not yet documented.

-#### Included tags ####
-
- - @ref pf_tag_mount Specifies the storages mounted on that host
- - @ref pf_tag_prop Specifies a user-defined property of that host, that you can retrieve with MSG_host_get_property_value() or simgrid::s4u::Host::property().
-
-#### Examples ####
-
-@code{.xml}
-<host id="host1" speed="1000000000"/>
-<host id="host2" speed="1000000000">
- <prop id="color" value="blue"/>
- <prop id="rendershape" value="square"/>
-</host>

-@anchor pf_host_dynamism
-### Expressing dynamism ###
-
-SimGrid provides mechanisms to change a hosts' availability over
-time, using the ``availability_file`` attribute to the ``@<host@>`` tag
-and a separate text file whose syntax is exemplified below.
-
-#### Adding a trace file ####
-
-@verbatim
-<platform version="4">
- <host id="bob" speed="500Gf" availability_file="bob.trace" />
-</platform>
-@endverbatim

-#### Example of "bob.trace" file ####

-Let us begin to explain this example by looking at line 2. (Line 1 will become clear soon).
-The first column describes points in time, in this case, time 0. The second column
-describes the relative amount of power this host is able to deliver (relative
-to the maximum performance specified in the ``@<host@>`` tag). (Clearly, the
-second column needs to contain values that are not smaller than 0 and not larger than 1).
-In this example, our host will deliver 500 Mflop/s at time 0, as 500 Mflop/s is the
-maximum performance of this host. At time 11.0, it will
-deliver half of its maximum performance, i.e., 250 Mflop/s until time 20.0 when it will
-will start delivering 80@% of its power. In this example, this amounts to 400 Mflop/s.
-
-Since the periodicity in line 1 was set to be 1.0, i.e., 1 timestep, this host will
-continue to provide 500 Mflop/s from time 21. From time 32 it will provide 250 MFlop/s and so on.
