Detailed Description

Provides an encapsulation to measure the system time.

This means the wall clock time used by the simulation, the CPU time used by all threads of a single process and the CPU time used by the overall simulation. (i.e., the time used by all threads of all involved processes.)

double Ewoms::Timer::cpuTimeElapsed ( ) const

inline

Return the CPU time [s] used by all threads of the local process.

If stop() was not yet called, this returns the time elapsed since the last call to start().

double Ewoms::Timer::globalCpuTimeElapsed ( ) const

inline

Return the CPU time [s] used by all threads of the all processes of the simulation.

If stop() was not yet called, this returns the time elapsed since the last call to start(). Note that this method must be called synchronously by all processes of the simulation...
