Using INTEL GPUs

[Joe_H]

Your log shows a CPU folding core running a CPU project WU on your CPU. Not a GPU job at all. Somehow the client managed to failsafe from your attempt to configure a slot for your Intel iGPU. There is no folding core that the systems would download to your PC process a GPU WU on your iGPU.

I think this says it all

[jetchko.jekov]

And here is the log from my notebook.
Notice it even says: OpenCL: Not detected: clGetDeviceIDs() returned -1. And yet it runs ...

Your log shows a CPU folding core running a CPU project WU on your CPU. Not a GPU job at all. Somehow the client managed to failsafe from your attempt to configure a slot for your Intel iGPU. There is no folding core that the systems would download to your PC process a GPU WU on your iGPU.

Hm? care to point out where is that exactly?

[Joe_H]

You are using Core_A7, that is a CPU only folding core. It does not run on a GPU.

Project 13861 is a CPU project.

Again, THERE IS NO GPU FOLDING CORE FOR INTEL. I am writing that way to emphasize you can't use what is not programmed for being used.

[jetchko.jekov]

Calm down, please and explain the meaning of this:

Also, there is no need to have a folding core especially for Intel GPUs, folding core for OpenCL is enough. Which Vendor GPU implements it should not matter.

[Joe_H]

The CPU core is ignoring the switches that do not apply to it, here is what he A7 core is actually using:

Code: Select all

17:16:58:WU00:FS01:0xa7:Calling: mdrun -s frame47.tpr -o frame47.trr -x frame47.xtc -e frame47.edr -cpi state.cpt -cpt 15 -nt 1

Look, you are not the first person who thought they could misconfigure the the client and force it to do something it was not meant to do. Usually they end up with something that results in the request for a WU being given a "Unable to assign" message. IN your case it was only off enough so it defaulted to sending your system a CPU WU, and that was run as a CPU WU on your system.

What ended up asa command to run it was, and you clipped that out of the second log:

Code: Select all

11:12:24:WU01:FS01:Running FahCore: /usr/bin/FAHCoreWrapper /var/lib/fahclient/cores/cores.foldingathome.org/v7/lin/64bit/avx/Core_a7.fah/FahCore_a7 -dir 01 -suffix 01 -version 705 -lifeline 1244 -checkpoint 15 -gpu-vendor amd -opencl-platform 0 -opencl-device 2 -gpu 2

Everything was normal up to the '-checkpoint' parameter, the core wrapper process ignored everything after that, and assigned default values. For instance, it ran on a single CPU thread '-nt 1'.

[jetchko.jekov]

Running processes in the system. I don't see wrapper ignoring anything.

See, I am just curious, I want to understand.

[Joe_H]

It may have those flags, but it is not passing them to the actual folding core, you will see that process as FAHCore_A7.

[jetchko.jekov]

exactly
look at 2nd line

[Joe_H]

The log shows what the core used, I have already posted that above. You can pass all kinds of garbage as input to programs, what they accepts another matter. In the case the core running showed exactly what it used in the log.

[jetchko.jekov]

OK, thanks for the patience

[jetchko.jekov]

Just 2 more questions:
How is it decided what core to be run on a particular slot?
Why is CPU only core run on GPU slot?

[JimboPalmer]

Currently all CPUs run the Core_a7, although there are two branches it might take, SSE2 and avx_256.
https://en.wikipedia.org/wiki/SSE2
https://en.wikipedia.org/wiki/Advanced_ ... Extensions

Modern CPUs will use avx_256.

GPUs run one of two Cores

Core_21 has many outstanding projects started with it, you would not change in mid stream, so until those project complete, you will sometimes see Core_21 WUs.

The newest AMD cards (code names like Navi and RDNA, models like 5x00 XT) were incompatible with Core_21 and a newer Core_22 was written, since it is newer, it does better science, and all new Projects are run with it. (all the COVID-19 WUs are Core_22, as they are all new, when we get back to treating cancer, etc. expect Core_21 again and slightly lower PPD)

https://en.wikipedia.org/wiki/List_of_F ... home_cores

[Neil-B]

Just 2 more questions:
How is it decided what core to be run on a particular slot?
Why is CPU only core run on GPU slot?

In a normal setup the core slots are defined by the client - If a setup has been modified the client still tries to get the right core for the right compute (or so it seems in your case) or it simply doesn't work and throws an error.

The scientists decide whether their project will use CPU, GPU and they set their projects up for this ... The AS looks at the incoming request for work and allocates to a WS with CPU WUs if it is CPU resource and to a WS with GPU WUs if it is a GPU resource ... This is complicated by many factors which the client manages - number of CPU cores available, Type of Graphics Card, etc. ... In standard configuration the client and the whole process works relatively well but when attempts to modify the way the client works beyond the intended limits that is when this can go awry ... In your case the AS managed to actually send you an extra CPU WU to run on a second CPU slot and ignore the extraneous information re GPU (which to be honest I am surprised it managed this).

So to answer your second question - it didn't, it can't, it won't - what you are seeing (as far as I understand it) is the system running two CPU slots ... but I am sure the developer (when he has sorted all the other infrastructure and workflow issues) may want to have a look at this and ensure it doesn't happen again.
