The situation was very unclear.bruce wrote:As I see the issue, you had a system with zero supported OpenCL GPUs but somehow it decided you could download a WU.
The reality was that there were 3 devices and that was recognized by OpenCL.
0x22 did find the GM206 correctly so and then downloaded.
Then 0x22 tried to "get the hook" and start, but at that time OpenCL failed to provide.
I did try to force device 0 but it did not make a difference.
0x22 did go for device 0, OpenCL just would not give it.
I found that interesting. In a way it is how OpenCL is supposed to work. But given the fact that four CPU cores won't get anything done it is fairly useless.By failing to find supported hardware, it decided to make 4 CPU cores busy doing nothing productive.
