Platform Examples
=================
-Here is a very simple platform file, containing 3 resources (two hosts
-and one link), and explicitly giving the route between the hosts.
+SimGrid comes with an extensive set of platforms in the
+`examples/platforms <https://framagit.org/simgrid/simgrid/tree/master/examples/platforms>`_
+directory.
-.. literalinclude:: ../../examples/platforms/two_hosts.xml
- :language: xml
+.. todo:: Write this page of the manual.
-The root tag must be ``<platform>``, and its ``version`` attribute
-specifies the used DTD version. When the DTD evolutions introduce
-backward-incompatible changes, this number gets updated. Use the
-``simgrid_update_xml`` utility to upgrade your platform files on need.
-
-
-Then, every platform element must be located within a given
-**networking zone** introduced with the :ref:`pf_tag_zone` tag. Zones
-are in charge of the routing: an host wants to communicate with
-another host of the same zone, it is the zone's duty to find the list
-of links that are involved in the communication. Here, since we use
-``routing="Full"``, all routes must be explicitly given using the
-:ref:`pf_tag_route` and :ref:`pf_tag_linkctn` tags (this :ref:`routing
-model <pf_rm>` is both simple and inefficient :) It is OK to not
-specify each and every route between hosts, as long as you don't start
-at runtime any communications on the missing routes.
-
-Any zone may contain sub-zones itself, leading to a hierarchical
-decomposition of the platform. This can be more efficient (as the
-inter-zone routing gets factorized with :ref:`pf_tag_zoneroute`), and
-allows to have more than one routing model in your platform. For
-example, you could have a coordinate-based routing for the WAN parts
-of your platforms, a full routing within each datacenter, and a highly
-optimized routing within each cluster of the datacenter. In this
-case, determining the route between two given hosts gets @ref
-routing_basics "somewhat more complex" but SimGrid still computes
-these routes for you in a time- and space-efficient manner.
-Here is an illustration of these concepts:
-
-.. image:: img/zone_hierarchy.png
-
-The zone "AS2" models the core of a national network interconnecting a
-small flat cluster (AS4) and a larger hierarchical cluster (AS5), a
-subset of a LAN (AS6), and a set of peers scattered around the world
-(AS7).
-
-.. todo:: Add more examples, such as the cloud example descibed in
- previous paragraph
+ Gather here the examples described elsewhere in the doc (SMPI tutorial, Platform intro), and describe the other ones.
