Thanks Remco. I don't understand this in depth because I don't know how opencl works within a GPU. However from your explanation I understand that there is a difference between - the maximum amount of GPU memory available for dt module processing (as per dt user manual > performance tuning) and - the maximum opencl can get in one allocation request. Marc.

See e.g. https://registry.khronos.org/OpenCL/sdk/3.0/docs/man/html/clGetDeviceInfo.html And of course, there usually are other programs also wanting GPU memory (desktop manager, Firefox, ...)
