9168 is the one just before, it's very recent and I'm not expecting it to fail (nor the new one to fix it then..), if the issue in your post was already with this driver, that means I need to investigate it more seriously, please confirm or let me know if it happens again.

Thanks! Will do. It's resumed ok for now. It does have this in the log:

.. so I'm going to see if I can see what value I should set opencl-index to.

..Think I've done that; explicitly set the index of the Nvidia GPU to 1 and the UHD Graphics to 2. Don't think that was related to the problem (but what do I know...)

[PeteHobbis]

It just did another restart (happens at 16:26). Here's the log, selected just Slot 02:

Would it -in theory- be possible to create WUs in the future where the Intel IGPUs and CPU fold together?

In theory this would be possible. The current Gromacs code that Core_A8 is based on includes support for using a GPU to accelerate some vector operations. This support has been tested with some discrete GPUs when Core_A8 in its early stages of development.

That said, there are some issues to be dealt with before this can be rolled out to use by F@h clients. First exact levels of OpenCL support required need to be determined and tested for. Next the client and server code will need some new code to handle this setup and usage of the hardware. For example, now the client detects the CPU and GPU separately and creates two separate folding slots. To use them together would require adjustments to the code so a single slot assigned to both hardware is able to be created.

It just did another restart (happens at 16:26). Here's the log,

That unit (project:13439 run:13063 clone:20 gen:1) finished successfully after its single core restart.

..but the next one (Project 13439, Run 13125, Clone 23, Gen 1) has done a restart at about 16%:

My gut instinct is a heat issue .. are you monitoring temps? .. on dgpus that message might imply oc stability issues but on a igpu I would hazard a guess at heat related instabilities if not driver (which I think you discounted)

[PeteHobbis]

I haven't been; I did for a while just after I first installed F@H. Set it to monitor just now; over the last twenty minutes, the CPU cores and the CPU graphics core are all saying 69-72 C. Course, nothing's going wrong just now..
Thanks!

[PeteHobbis]

I had another WU from project 13439 abort after a second 'particle coordinate is nan', so I set the igpu to finish; it completed that last unit successfully after one core restart. I've left the igpu paused for now.

To use them together would require adjustments to the code so a single slot assigned to both hardware is able to be created.

Using the iGPU concurrently with the CPU (whether on the same WU or on different WUs ) would compound the potential for heat dissipation issues. While I'm in favor of continuing development of the concept of using both features on a single WU, all the heat from both devices ends up going through a potentially weak common path to air. We can expect to see more instabilities on overheated CPU-iGPU devices due to a weak heatsink.

FACTS:
The Intel iGPs are extremely slow compared to other GPUs. Also if you also fold with a CPU slot, it will slow down, increasing your total throughput only slightly. In other words, don't expect much.

Speed it really important to FAH projects and slow GPUs do slow down the whole project. Therefore assignments to your iGP will often be throttled. There may or may not be specific projects that will benefit from assigning WUs to Intel iGPs.

Would it -in theory- be possible to create WUs in the future where the Intel IGPUs and CPU fold together?

It is possible to not waste CPU time to service (i)GPU but it requires some efforts from Folding@home developers. CPU+iGPU is more efficient than CPU only. I have posted details and sample source code here.

Using the iGPU concurrently with the CPU (whether on the same WU or on different WUs ) would compound the potential for heat dissipation issues.

Modern CPUs automatically adjust CPU/iGPU frequencies to achieve desired TDP. Please see my benchmarks at the link above (that's distributed.net client but idea is the same). Performance improves, power consumption (heat dissipation) does not increase.

While I'm in favor of continuing development of the concept of using both features on a single WU, all the heat from both devices ends up going through a potentially weak common path to air. We can expect to see more instabilities on overheated CPU-dGPU devices due to a weak heatsink.

dGPU?

[bruce]

No. it should say iGPU. Corrected in the original post but not in your quote of it.

[Ale_F]

I tried to use iGPU on my i7100. All works fine. Compared to CPU only, I found that the improvement is near zero because the iGPU works at max 5% (which is not related to FAH).
I removed the gpu-beta option, but at restart the red tongue remain. Interestingly, if I check on FAH Control, slowly, but the slot is folding and a CPU core is busy.

So, what is the system to remove totally the red tongue and move the CPU slot to fold... a real CPU WU (like the other two cores)?

[bruce]

One possibilitY: see my reply here

It really helps if you include the beginning of the log. (It saves a lot of guessing.)
