Guessing ambiguous GPU to OpenCL device ...

Post by promeneur »

I get this warning about my intel igpu:

16:04:47:WARNING:FS01:Guessing ambiguous GPU to OpenCL device mapping for 01: gpu:0:2 KBL GT2 [HD Graphics 630]. Consider upgrading your graphics driver or manually setting ``opencl-index`` in this slot's configuration.

Where to find the value to assign to ``opencl-index`` ?

Thanks

Thanks, but I use Linux, and it is not my question.

you must manally set opencl-index ?

I found the solution.

Here is my config:

06:44:08: GPUs: 2
06:44:08: GPU 0: Bus:0 Slot:2 Func:0 INTEL:1 KBL GT2 [HD Graphics 630]
06:44:08: GPU 1: Bus:1 Slot:0 Func:0 NVIDIA:3 GK208B [GeForce GT 730] 692.7
06:44:08: CUDA Device 0: Platform:0 Device:0 Bus:1 Slot:0 Compute:3.5 Driver:11.4
06:44:08:OpenCL Device 0: Platform:0 Device:0 Bus:NA Slot:NA Compute:2.0 Driver:1.3
06:44:08:OpenCL Device 1: Platform:1 Device:0 Bus:1 Slot:0 Compute:3.0 Driver:470.86

the problem is about GPU 0: Bus:0 Slot:2 Func:0 INTEL:1 KBL GT2 [HD Graphics 630]
so I add "opencl-index" with value "0" in this gpu settings with fah-control in tab "slot" (you must stop fah-client)

I understand fah does not know what opencl to use for the intel igpu HD Graphics 630.
it must be use the OpenCL Device 0 which is the opencl for intel igpu and not the OpenCL Device 1 which is for the nvidia card.

OpenCL Device 0 <=> opencl-index = 0
