Fedora 31, Nvidia GT 1030: clGetDeviceIDs() returned -1

CPU folding on a 12-core Threadripper is still a decent contribution to be able to make to the cause.

Absolutely!

I've been struggling with this same issue on F31 KDE w/ an intel CPU and Nvidia card.
Just resolved it today the clGetDeviceIDs() error.

I had to remove the pre-installed mesa drivers.

Code: Select all

mesa-libOpenCL
mesa-libOpenCL-devel

Reboot and finally saw this:

Code: Select all

02:24:28:           GPUs: 1
02:24:28:          GPU 0: Bus:5 Slot:0 Func:0 NVIDIA:7 GP106 [GeForce GTX 1060 3GB] 3935
02:24:28:  CUDA Device 0: Platform:0 Device:0 Bus:5 Slot:0 Compute:6.1 Driver:10.2
02:24:28:OpenCL Device 0: Platform:0 Device:0 Bus:5 Slot:0 Compute:1.2 Driver:440.64

However, now when starting the FAHClient, FAHCore starts, but soon after displays this error.

Code: Select all

02:24:29:WU01:FS01:FahCore returned: INTERRUPTED (102 = 0x66)

FAH seems to not handle multiple OpenCL platforms well. Uninstalling POCL and whatever the Intel OpenCL you have installed.

Was this issue ever resolved?

The Intel iGPU is currently unsupported but the GT1030 should be although it's not a particularly powerful GPU.

We're working on a fix for this in the new client bugfix release!
