Hi,
I continue my development tests and I discovered that OpenCL does not work with Resolve 17.2 studio Windows GTX2070 (drivers 466.47) nor on Linux GTX2060 drivers 465), nor on Linux with a Quadro K1100M.

But it works perfectly with NVidia 452.57 and a GTX1660Ti

Perhaps an explaination:
I wrote this short code

Code: Select all

#include <CL/cl2.hpp>
#include <iostream>

int main (int argc, char *argv[]) {
std::vector<cl::Platform> platforms;
std::string               str;

cl::Platform::get(&platforms);
platforms[0].getInfo(CL_PLATFORM_VERSION, &str);
std::cout <<  str << std::endl;
}

With driver version 450.119.04 it gives
OpenCL 1.2 CUDA 11.0.228
But with drivers version 465.19.01
OpenCL 3.0 CUDA 11.3.55

So NVidia changes the default API layer...
