Revision history [back]

Hi,

in OpenCL, I have studied the ocl_test.cpp. Retrieving information about my system (Windows 7 SP1, 32bit) concerning available CPUs, GPUs and so on works fine. Studying the documentation, I have not found a way to set the device to do the actual computations.

In an older version of openCV, I saw a method like "setDevice", which is not available in the 3.0 beta. So, how can I enable a specific device for further computations? I only found a method called "set" which accepts a void-pointer. Since my GPU (device 0) is not the newest model I would like to enable my multicore-CPU (following device 1).

Thanks for your tips! Johannes
