Detailed Description

Kokkos_Time: The Kokkos Timing Class.

The Kokkos_Time class is a wrapper that encapsulates the general information needed getting timing information. Currently it return the elapsed time for each calling processor.. A Kokkos_Comm object is required for building all Kokkos_Time objects.

Kokkos_Time support both serial execution and (via MPI) parallel distributed memory execution. It is meant to insulate the user from the specifics of timing across a variety of platforms.

Constructor & Destructor Documentation

Kokkos::Time::Time

(

)

[inline]

Time Constructor.

Creates a Time instance. This instance can be queried for elapsed time on the calling processor. StartTime is also set for use with the ElapsedTime function.

Kokkos::Time::Time

(

const Time &

time

)

[inline]

Time Copy Constructor.

Makes an exact copy of an existing Time instance.

virtual Kokkos::Time::~Time

(

)

[inline, virtual]

Kokkos_Time Destructor.

Completely deletes a Kokkos_Time object.

Member Function Documentation

double Kokkos::Time::elapsedTime

(

)

const [inline]

Kokkos_Time elapsed time function.

Returns the elapsed time in seconds since the timer object was constructed, or since the ResetStartTime function was called. A code section can be timed by putting it between the Kokkos_Time constructor and a call to ElapsedTime, or between a call to ResetStartTime and ElapsedTime.

void Kokkos::Time::resetStartTime

(

)

[inline]

Kokkos_Time function to reset the start time for a timer object.

Resets the start time for the timer object to the current time A code section can be timed by putting it between a call to ResetStartTime and ElapsedTime.

double Kokkos::Time::wallTime

(

)

const [inline]

Time wall-clock time function.

Returns the wall-clock time in seconds. A code section can be timed by putting it between two calls to wallTime and taking the difference of the times.
