The concept of an AS was already outlined above (Section \ref pf_basics);
recall that the AS is so important because it groups other resources (such

A <b>host</b> represents a computer/node card. Every host is able to execute
code and it can send and receive data to/from other hosts. Most importantly,

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

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

``<cluster />`` represents a machine-cluster. It is most commonly used
when one wants to define many hosts and a network quickly. Technically,
prefix | yes | string | Each node of the cluster has to have a name. This name will be prefixed with this prefix.
suffix | yes | string | Each node of the cluster will be suffixed with this suffix
radical | yes | string | Regexp used to generate cluster nodes name. Syntax: "10-20" will give you 11 machines numbered from 10 to 20, "10-20;2" will give you 12 machines, one with the number 2, others numbered as before. The produced number is concatenated between prefix and suffix to form machine names.
-power | yes | int | Same as the ``power`` attribute of the ``<host>`` tag.
-core | no | int (default: 1) | Same as the ``core`` attribute of the ``<host>`` tag.

This tag represents a peer, as in Peer-to-Peer (P2P) networks. However, internally,
SimGrid transforms a peer into an AS (similar to Cluster). Hence, this tag
