bool simgrid::s4u::this_actor::isMaestro |
( |
| ) |
|
Returns true if run from the kernel mode, and false if run from a real actor.
Everything that is run out of any actor (simulation setup before the engine is run, computing the model evolutions as a result to the actors' action, etc) is run in kernel mode, just as in any operating systems.
In SimGrid, the actor in charge of doing the stuff in kernel mode is called Maestro, because it is the one scheduling when the others should move or wait.
