Using Nvidia OpenCL-drivers with an ICD-loader on Windows

Question

I have configured Installable Client Drivers (ICDs) on an Ubuntu-distribution with Intel OpenCL runtime drivers, which was fairly straightforward. These drivers come as *.so-files which can be loaded by specifying their path in an *.icd -file under /etc/OpenCL/vendors/ .

How would I proceed to specify Nvidia OpenCL-drivers on Windows, and where are these drivers located?

I use MINGW64 with and OpenCL-ICD-Loader installed via MSYS2

Where is the corresponding directory to add the *.icd -files?

Answer 1

On Windows with MinGW-w64 I use a combination of:

• https://github.com/KhronosGroup/OpenCL-Headers
• https://github.com/KhronosGroup/OpenCL-ICD-Loader

OpenCL-ICD-Loader figures out where to load the Nvidia stuff from.

To build from source I had to tweak some stuff, see my build recipes:
