+
+The simulation models in SimGrid have been object of thorough validation/invalidation campaigns, but the default values may
+not be appropriate for simulating a particular system.
+
+They are configured
+through parameters from the :ref:`XML platform description file <platform>` and parameters passed via
+:ref:`--cfg=Item:Value command-line arguments <options>`. A simulator may also include any number of custom model
+parameters that are used to instantiate particular simulated activities (e.g., a simulator developed with the S4U API
+typically defines volumes of computation, communication, and time to pass to methods such as :cpp:func:`execute()
+<simgrid::s4u::this_actor::execute>`, :cpp:func:`put() <simgrid::s4u::Mailbox::put>`, or :cpp:func:`sleep_for()
+<simgrid::s4u::this_actor::sleep_for>`). Regardless of the potential accuracy of the simulation models, if they are
+instantiated with unrealistic parameter values, then the simulation will be inaccurate.
+
+Given the above, an integral and crucial part of simulation-driven research is **simulation calibration**: the process by
+which one picks simulation parameter values based on observed real-world executions so that simulated executions have high
+accuracy. We then say that a simulator is "calibrated". Once a simulator is calibrated for a real-world system, it can be
+used to simulate that system accurately. But it can also be used to simulate different but structurally similar systems
+(e.g., different scales, different basic hardware characteristics, different application workloads) with high confidence.
+
+Research conclusions derived from simulation results obtained with an uncalibrated simulator are questionable in terms of
+their relevance for real-world systems. Unfortunately, because simulation calibration is often a painstaking process, is it
+often not performed sufficiently thoroughly (or at all!). We strongly urge SimGrid users to perform simulation calibration.
+Here is an example of a research publication in which the authors have calibrated their (SimGrid) simulators:

you can see, this article is a must read. It's a pity that it's not
