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)

for the current thread.
-
getReportCurrentThread
public java.lang.ref.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 withProfileReport.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 java.lang.ref.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 withProfileReport.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)
