problem with quadro M2000M

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

Hi, for whatever reason OpenCL is not working:

here is the icd and OpenCL configuration:

any idea what could be the reason?

Welcome to the F@H Forum mtruchado,

From what I have read, you need to have Nvidia proprietary drivers (not the open sourced ones) and you need to install OpenCL package for GPU folding to work

It´s there, look:

Code: Select all
  Platform Name                                   NVIDIA CUDA
Number of devices                                 1
  Device Name                                     Quadro M2000M
  Device Vendor                                   NVIDIA Corporation

this is the driver version:

Code: Select all
 Driver Version                                  410.104

The laptop is a g3 zbook from HP which includes this gpu. It´s working flawlessly in windows by the way.

Oh by the way, the laptop does not even starting if nouveau module is being loaded, hence It´s blacklisted

The OpenCL error I was having on Fedora was from the ocl-icd-devel package missing (maybe different pkg name on Ubuntu). I previously had the from the mesa-libOpenCL package, which I uninstalled.

There are also files in /etc/OpenCL/vendors that list which versions of the library are installed. I had to have only one file there that lists
