3 weeks ago Thanks for sharing that (and sorry to be a little slow). It looks like you've resolved the issue for your setup. Are you recommending a change to the cmake file to support all GPUs? That's been an outstanding issue for quite some time. Please feel free to propose a PR or send a diff.
I got an error using the laptop gpu compiler.
My system specs are: CPU: i7-12700H GPU: NVIDIA GeForce RTX 3060 Laptop GPU RAM: 32Gb ddr5 OS:Ubuntu22.04 Motherboard vendor: HP
The relevant information is as follows:

So I read the SetupCUDA.cmake file and added Laptop GPU support, as follows: foreach(GPU_LINE ${__out}) string(REGEX REPLACE "GPU [0-9]: (.) \(UUID: ." "\1" GPU_NAME ${GPU_LINE}) string(REGEX REPLACE "GeForce " "" GPU_NAME ${GPU_NAME}) string(REGEX REPLACE "N[Vv][Ii][Dd][Ii][Aa] " "" GPU_NAME ${GPU_NAME}) string(REGEX REPLACE " Laptop GPU" "" GPU_NAME ${GPU_NAME}) # Added support for Laptop Gpus get_compute_for_gpu(GPU_COMPUTE ${GPU_NAME}) message(STATUS "GPU found: " ${GPU_NAME} ", compute " ${GPU_COMPUTE}) if(CUDA_ALL_ARCHES) if(NOT GPU_COMPUTE IN_LIST ALLCOMPUTES) set(TEMP "${TEMP} -gencode arch=compute${GPUCOMPUTE},code=sm${GPU_COMPUTE}") list(APPEND ALL_COMPUTES "${GPU_COMPUTE}") endif() else() if(ALL_COMPUTES) set(WARN_MULTI_ARCH 1) if(NOT GPU_COMPUTE GREATER ALLCOMPUTES) continue() endif() endif() set(TEMP "-gencode arch=compute${GPUCOMPUTE},code=sm${GPU_COMPUTE}") set(ALL_COMPUTES "${GPU_COMPUTE}") endif() endforeach()
I do not know if there is a better way, looking forward to your reply
