\section options_model Configuring the platform models
\anchor options_storage_model
If you compiled SimGrid accordingly, you can use packet-level network
simulators as network models (see \ref pls_ns3). In that case, you have
-two extra models, described below, and some \ref options_pls "specific
-additional configuration flags".

- \b NS3: Network pseudo-model using the NS3 tcp model
Concerning the CPU, we have only one model for now:
that allows the simulation kernel to control its execution: when a user
process requires a blocking action (such as sending a message), it is
interrupted, and only gets released when the simulated clock reaches
-the point where the blocking operation is done.
+the point where the blocking operation is done. This is explained
+graphically in the [relevant tutorial, available online](http://simgrid.gforge.inria.fr/tutorials/simgrid-simix-101.pdf).
In SimGrid, the containers in which user processes are virtualized are
called contexts. Several context factory are provided, and you can
machine because of portability issues. In any case, the default one
should be the most effcient one (please report bugs if the
auto-detection fails for you). They are approximately sorted here from
-the slowest to the most effient:

pthreads or windows native threads). They are slow but very
It can be done by using XBT. Go to \ref XBT_log for more details.
