Detailed Description

A class that can be used measure time on Linux systems.

A timer class that uses the linux function gettimeofday() to measure time. The resolution can vary on different systems but is usually a few micro seconds. Can be checked with getResolutionUs(). Stores all times taken, between a start and a stop, as seperate runs and they exists until timer is reset. Both total time of all runs and average can be returned.

Member Function Documentation

double skepu::TimerLinux_GTOD::getAverageTime ( )

inline

Returns

Average time of all stored runs.

double skepu::TimerLinux_GTOD::getMaxTime ( )

inline

Returns

Max time of all stored runs.

References skepu::max().

Here is the call graph for this function:

double skepu::TimerLinux_GTOD::getMinTime ( )

inline

Returns

Minimum time of all stored runs.

References skepu::min().

Here is the call graph for this function:

int skepu::TimerLinux_GTOD::getNumTimings ( )

inline

Returns

Number of runs stored in timer.

double skepu::TimerLinux_GTOD::getResolutionUs ( )

inline

Returns

The resolution of the timer in micro seconds.

double skepu::TimerLinux_GTOD::getTime ( int  run = 0 )

inline

Parameters

run	The run to get timing of.

Returns

Time for a certain run.

double skepu::TimerLinux_GTOD::getTotalTime ( )

inline

Returns

Total time of all stored runs.

void skepu::TimerLinux_GTOD::reset ( )

inline
