I found a solution

I add for gpu slot

cuda-index = 0
opencl-index = 0
gpu-index = 0

Now fah finds nvidia cuda and nvidia opencl !!! Victory.

Thanks to internet searching.

adding for gpu slot

cuda-index = 0
opencl-index = 0
gpu-index = 0

does not work.
We must run "clinfo" before fahclient at PC starting.

I put "clinfo" command in a custom service. This service happily (I don't know why) is started before fahclient.

It works.
Now fahclient find cuda and opencl.
