![]() ![]() We need to specify where the OpenCL headers are located by adding the path to the OpenCL “CL” is in the same location as the other CUDA include files, that is, CUDA_INC_PATH. Printf("\nError calling clGetPlatformIDs. Printf("\nDetected OpenCL platforms: %d", numPlatforms) To begin with, we need to check how many OpenCL platforms are available in the system: #includeĮrr = clGetPlatformIDs(0, NULL, &numPlatforms) ![]() Let’s assume that we are developing a 64bit C/C++ application using Visual Studio 2013. Grab any of these in order to have everything ready for building OpenCL code.Īs long as you pay attention to the OpenCL version and the OpenCL features supported by your device, you can use the OpenCL headers and libraries from any of these three vendors. Intel – the previous Intel SDK for OpenCL is now integrated into Intel’s new tools, such as Intel INDE (which has a free starters edition) or Intel Media Server Studio.OpenCL SDKsįor OpenCL headers and libraries the main options you can choose from are: Ok, so let’s have a look into each of these. Run and prepare to be awed in amazement.Tell the linker where to find the OpenCL.Tell the compiler where the OpenCL headers are located.Get the OpenCL headers and libraries included in the OpenCL SDK from your favourite vendor.Make sure you have a machine which supports OpenCL, as described above.Now it’s time to put the pedal to the metal and start developing some proper OpenCL applications. Or it may require a certain OpenCL version that your device does not support.Ī great tool that will allow you to retrieve the details for the OpenCL devices in your system is Caps Viewer. For example, the application may run only on OpenCL CPUs, or conversely, on OpenCL GPUs. Look for device type and OpenCL version in particular. In addition, it is always a good idea to check for any other special requirements that the OpenCL application may have. NVIDIA’s GPU-drivers mention mostly CUDA, but the drivers for OpenCL 1.1 1.2 are there too.AMD’s GPU-drivers include the OpenCL-drivers for CPUs, APUs and GPUs, version 2.0.Intel has hidden them a bit, but you can find them here with support for OpenCL 2.0.Here is where you can download drivers manually: ![]() With certain older devices OpenCL support wasn’t initially included in the drivers.
