Method Summary

Modifier and Type	Method	Description
String	getAverageAsTableRow()
String	getCumulativeAsTableRow()
double	getCumulativeElapsedTimeAllCurrentThread()	Elapsed time of entire execution, summed over all executions, for the current thread, if it has executed the kernel on the device assigned to this KernelDeviceProfile instance.
double	getCumulativeElapsedTimeAllGlobal()	Elapsed time of entire execution, summed over all executions, for all the threads, that executed the kernel on this device.
double	getCumulativeElapsedTimeCurrrentThread(ProfilingEvent stage)	Elapsed time for a single event only, i.e.
double	getCumulativeElapsedTimeGlobal(ProfilingEvent stage)	Elapsed time for a single event only, i.e.
double	getElapsedTimeCurrentThread(int stage)	Elapsed time for a single event only and for the current thread, i.e.
double	getElapsedTimeCurrentThread(int from, int to)	Elapsed time for all events from through to for the current thread.
double	getElapsedTimeLastThread(int stage)	Elapsed time for a single event only and for the last thread that finished executing a kernel, i.e.
double	getElapsedTimeLastThread(int from, int to)	Elapsed time for all events from through to for the last thread that executed this KernelDeviceProfile instance respective kernel and device.
String	getLastAsTableRow()
WeakReference<ProfileReport>	getReportCurrentThread()	Retrieves the most recent complete report available for the current thread calling this method. Note1: If the profile report is intended to be kept in memory, the object should be cloned with ProfileReport.clone() Note2: If the thread didn't execute this KernelDeviceProfile instance respective kernel and device, it will return null.
WeakReference<ProfileReport>	getReportLastThread()	Retrieves the most recent complete report available for the last thread that executed this KernelDeviceProfile instance respective kernel and device.

Constructor Details

KernelDeviceProfile

public KernelDeviceProfile(KernelProfile parentProfile,
 Class<? extends Kernel> kernel,
 Device device)

Method Details

onEvent

public void onEvent(ProfilingEvent event)

getElapsedTimeCurrentThread

public double getElapsedTimeCurrentThread(int stage)

Elapsed time for a single event only and for the current thread, i.e. since the previous stage rather than from the start.

getElapsedTimeCurrentThread

public double getElapsedTimeCurrentThread(int from,
 int to)

Elapsed time for all events from through to for the current thread.

getReportCurrentThread

public WeakReference<ProfileReport> getReportCurrentThread()

Retrieves the most recent complete report available for the current thread calling this method.
Note1: If the profile report is intended to be kept in memory, the object should be cloned with ProfileReport.clone()
Note2: If the thread didn't execute this KernelDeviceProfile instance respective kernel and device, it will return null.

Returns:

• the profiling report for the current most recent execution
• null, if no profiling report is available for such thread

getReportLastThread

public WeakReference<ProfileReport> getReportLastThread()

Retrieves the most recent complete report available for the last thread that executed this KernelDeviceProfile instance respective kernel and device.
Note1: If the profile report is intended to be kept in memory, the object should be cloned with ProfileReport.clone()

Returns:

• the profiling report for the current most recent execution
• null, if no profiling report is available yet

getCumulativeElapsedTimeCurrrentThread

public double getCumulativeElapsedTimeCurrrentThread(ProfilingEvent stage)

Elapsed time for a single event only, i.e. since the previous stage rather than from the start, summed over all executions, for the current thread, if it has executed the kernel on the device assigned to this KernelDeviceProfile instance.

Parameters:

stage - the event stage

getCumulativeElapsedTimeAllCurrentThread

public double getCumulativeElapsedTimeAllCurrentThread()

Elapsed time of entire execution, summed over all executions, for the current thread, if it has executed the kernel on the device assigned to this KernelDeviceProfile instance.

getElapsedTimeLastThread

public double getElapsedTimeLastThread(int stage)

Elapsed time for a single event only and for the last thread that finished executing a kernel, i.e. single event only - since the previous stage rather than from the start.

Parameters:

stage - the event stage

getElapsedTimeLastThread

public double getElapsedTimeLastThread(int from,
 int to)

Elapsed time for all events from through to for the last thread that executed this KernelDeviceProfile instance respective kernel and device.

Parameters:

from - the first event to consider that defines the elapsed period start

to - the last event to consider for elapsed period

getCumulativeElapsedTimeGlobal

public double getCumulativeElapsedTimeGlobal(ProfilingEvent stage)

Elapsed time for a single event only, i.e. since the previous stage rather than from the start, summed over all executions, for the last thread that executed this KernelDeviceProfile instance respective kernel and device.

Parameters:

stage - the event stage

getCumulativeElapsedTimeAllGlobal

public double getCumulativeElapsedTimeAllGlobal()

Elapsed time of entire execution, summed over all executions, for all the threads, that executed the kernel on this device.

getTableHeader

public static String getTableHeader()

getLastAsTableRow

public String getLastAsTableRow()

getCumulativeAsTableRow

public String getCumulativeAsTableRow()

getAverageAsTableRow

public String getAverageAsTableRow()

toString

public String toString()

Overrides:
