may speedup the simulation by discarding very small actions, at the
price of a reduced numerical precision.
+\subsection options_model_nthreads Parallel threads for model updates
+
+By default, Surf computes the analytical models sequentially to share their
+resources and update their actions. It is possible to run them in parallel,
+using the \b surf/nthreads item (default value: 1).
+Depending on the workload of the models and their complexity, you may get a
+speedup or a slowdown because of the synchronization costs of threads.

\subsection options_model_network Configuring the Network model
\subsubsection options_model_network_gamma Maximal TCP window size
available in <tt>examples/msg/gtnets/crosstraffic-p.xml</tt>.
This is activated through the \b network/crosstraffic item, that
-can be set to 0 (disable this feature) or 1 (enable it).
+can be set to 0 (disable this feature) or 1 (enable it).
+
+Note that with the default workstation model this option is activated by default.
