Opm::Timer
Provides an encapsulation to measure the system time.
Definition timer.hpp:46
Opm::Timer::reset
void reset()
Make the current point in time t=0 but do not change the status of the timer.
Definition timer.cpp:82
Opm::Timer::start
void start()
Start counting the time resources used by the simulation.
Definition timer.cpp:46
Opm::Timer::elapsed
double elapsed() const
This is an alias for realTimeElapsed().
Definition timer.hpp:92
Opm::Timer::halt
void halt()
Stop the measurement reset all timing values.
Definition timer.cpp:75
Opm::Timer::realTimeElapsed
double realTimeElapsed() const
Return the real time [s] elapsed during the periods the timer was active since the last reset.
Definition timer.cpp:90
Opm::Timer::globalCpuTimeElapsed
double globalCpuTimeElapsed() const
Return the CPU time [s] used by all threads of the all processes of program.
Definition timer.cpp:122
Opm::Timer::operator+=
Timer & operator+=(const Timer &other)
Adds the time of another timer to the current one.
Definition timer.cpp:140
Opm::Timer::stop
double stop()
Stop counting the time resources.
Definition timer.cpp:52
Opm::Timer::cpuTimeElapsed
double cpuTimeElapsed() const
Return the CPU time [s] used by all threads of the local process for the periods the timer was active...
