Data Structures and Utility Functions

ocl::getOpenCLPlatforms

Returns the list of OpenCL platforms

C++: int ocl::getOpenCLPlatforms(PlatformsInfo& platforms)

Parameters:

• platforms – Output variable

ocl::getOpenCLDevices

Returns the list of devices

C++: int ocl::getOpenCLDevices(DevicesInfo& devices, int deviceType=CVCL_DEVICE_TYPE_GPU, const PlatformInfo* platform=NULL )

Parameters:

• devices – Output variable
• deviceType – Bitmask of CVCL_DEVICE_TYPE_GPU, CVCL_DEVICE_TYPE_CPU or CVCL_DEVICE_TYPE_DEFAULT.
• platform – Specifies preferrable platform

ocl::setDevice

Returns void

C++: void ocl::setDevice(const DeviceInfo* info)

Parameters:

• info – device info

ocl::setBinaryPath

Returns void

C++: void ocl::setBinaryPath(const char* path)

Parameters:

• path – the path of OpenCL kernel binaries

If you call this function and set a valid path, the OCL module will save the compiled kernel to the address in the first time and reload the binary since that. It can save compilation time at the runtime.
