apTimer Class Reference

Timer that can be started, stopped and measure its working time usually timer corresponds to some process, for example solving number of equations timer can be part of some timers hierarchy which corresponds to hierarchy of processes, for example solving of some equations is part of modeling of some physical process (upper level process), but it has as a part solving of one particular equation (lower level process).

Detailed Description

Timer that can be started, stopped and measure its working time usually timer corresponds to some process, for example solving number of equations timer can be part of some timers hierarchy which corresponds to hierarchy of processes, for example solving of some equations is part of modeling of some physical process (upper level process), but it has as a part solving of one particular equation (lower level process).

hierarchy of timers should correspond this hierarchy of processes. starting lower level timer causes starting upper level timers, so upper level timers should summate time measured by their lower level timers.

Member Function Documentation

gettime()

static double apTimer::gettime ( bool  local = true )

static

If local==true, it will be time on current processor, otherwise time on zero processor of mpi.

If USE_MPI is not defined it fallbacks to real time, mesured by high_resolution_clock.

Returns

current time in seconds.
