\subsection{Simulator}\label{simulator}

An executable called {\var xkernel} will reside in the build
directory after following the procedures described in
Section~\ref{config}.  To run the simulation, change to a directory
containing the {\var xsim.data}, {\var rom}, and protocol table
files, and invoke the executable.

Note that the {\xk} executable created by the simulator is of a
different order than the user\_level executable.  For the latter,
each invocation of the executable corresponds to exactly one host
instance.  However, invoking the simulator runs the entire simulation,
which may potentially include thousands of hosts communicating over a
variety of networks.
