Detailed Description

A timer using kernels for timing on a DpcppExecutor in profiling mode.

Member Function Documentation

difference_async()

std::chrono::nanoseconds gko::DpcppTimer::difference_async ( const time_point &  start, const time_point &  stop  )

overridevirtual

Computes the difference between the two time points in nanoseconds. This asynchronous version does not synchronize itself, so the time points need to have been synchronized with, i.e. timer->wait(stop) needs to have been called. The version is intended for more advanced users who want to measure the overhead of timing functionality separately.

Parameters

start	the first time point (earlier)
end	the second time point (later)

Returns

the difference between the time points in nanoseconds.

Implements gko::Timer.

init_time_point()

void gko::DpcppTimer::init_time_point ( time_point &  time )

overrideprotectedvirtual

Initializes a new time_point instance for this timer.

Implements gko::Timer.

record()

void gko::DpcppTimer::record ( time_point &  time )

overridevirtual

Records a time point at the current time.

Implements gko::Timer.

wait()

void gko::DpcppTimer::wait ( time_point &  time )

overridevirtual

Waits until all kernels in-process when recording the time point are finished.

Implements gko::Timer.
