simgrid::SimulationClock Struct Reference

Detailed Description

A C++ compatible TrivialClock working with simulated-time.

SimGrid uses double for representing the simulated time, where durations are expressed in seconds (with infinite duration expressed as a negative value) and timepoints are expressed as seconds from the beginning of the simulation. In contrast, all the C++ APIs use the much more sensible std::chrono::duration andstd::chrono::time_point.

This class can be used to build std::chrono objects that use simulated time, using SimulationClockDuration and SimulationClockTimePoint.

This means it is possible to use (since C++14):

using namespace std::chrono_literals;
simgrid::s4u::actor::sleep_for(42s);

#include <chrono.hpp>
