OpenCL性能评估 [英] OpenCL performance measurement

问题描述

呈现OpenCL应用程序(尤其是计算内核)性能的最合适方法是什么? 我已经实现了一些算法，并且正在考虑呈现速度和效率图表，但是根据定义，我需要知道我在计算中使用了多少个处理器.如果使用OpenCL，则无法完成.

What is the most appropriate method to present a performance of OpenCL application (especially computing kernels)? I have implemented some algorithms and I was thinking about presenting speed-up and efficiency charts, but according to the definition I need to know how many processors I have used in calculations. In case of OpenCL it can not be done.

推荐答案

创建带有CL_QUEUE_PROFILING_ENABLE标志集的命令队列，然后使用clGetEventProfilingInfo提取时序数据.有关更多详细信息，请参见"OpenCL编程指南"的第9章.

Create your command queue with the CL_QUEUE_PROFILING_ENABLE flag set, then use clGetEventProfilingInfo to extract timing data. See Chapter 9 of "OpenCL Programming Guide" for more details.
