communications have an influence on computational power. Should it be taken
into account too?
-So, we decided not to include such a function into MSG and let people do it
-thereselves so that they get the value matching exactly what they mean. One
-possibility is to run active measurement as in next code snippet. It is very
-close from what you would have to do out of the simulator, and thus gives
-you information that you could also get in real settings to not hinder the
-realism of your simulation.
+First of all, it's near to impossible to predict the load beforehands in the
+simulator since it depends on too much parameters (background load
+variation, bandwidth sharing algorithmic complexity) some of them even being
+not known beforehands (other task starting at the same time). So, getting
+this information is really hard (just like in real life). It's not just that
+we want MSG to be as painful as real life. But as it is in some way
+realistic, we face some of the same problems as we would face in real life.

+How would you do it for real? The most common option is to use something
+like NWS that performs active probes. The best solution is probably to do
+the same within MSG, as in next code snippet. It is very close from what you
+would have to do out of the simulator, and thus gives you information that
+you could also get in real settings to not hinder the realism of your
+simulation.
