Question: How to do gpu mining with Intel Iris on macOS? #1539

Closed nottoseethesun closed 6 years ago

nottoseethesun commented 6 years ago

I see that some users are utilizing a similar set-up and having gpu usage, but currently I only have cpu mining with xmr-stak (checked gpu usage monitor), although I built using the AMD commands. I filled out all the info below:

It's possible but the mining speed is so slow that it's probably not worth the time or electricity cost.

I see that some users are utilizing a similar set-up and having gpu usage

Can you link to where you saw this?

Save your time and miner on cpu or amd, nvidia. Intel is not able to build gpus for computing. the gpus are slow and stile RAM from the cpu and than your cpu is also slow.

You would have to hack the code and possibly adjust some of the OpenCL calls (standard? more like loose club...) There used to be an old PR that had most of the hacks but the code has changed since then... more of a follow the crumbs. But it mentioned Intel in the title...

And then at the end of it all you can mine 25H/s and feel cheated out of all the effort, and just use the 50H/s CPU alone. If it is an iGPU (in the CPU) then you won't be able to CPU mine at the same time, they stomp on the same unified cache. If it is non-embedded discrete somehow, it still says it is on system memory (not GDDR5 of its own, local) so you can't even really use the GPU 'power' that is available, the ram is just too slow and holds it back like a parachute (therefore the useless hashrate)

That thread seems to allude that parts of the Intel don't fully work anyway, and this uses that cl_khr_fp64 but not immediately sure if also using exp() anywhere. So you may not ever manage to see the horrible watt-chewing rate it might get.

Responding to @uvtzxpm : This post has discussion of a system with Iris on it (but also nvidia): https://github.com/fireice-uk/xmr-stak/issues/326

Thanks all for the great info, that answers the question pretty well. Closing this then.
