Hello,

several other projects have started to support the Intel ARC GPUs
their power combined with their lower power consumption compared the NVIDIA/AMD make them very BOINC friendly

Will we see app for them at some point ?

thank you

Both AMD and NVIDIA use the same OpenCL application here, so if Intel drivers are stable enough to run it, it's possible. You can run the GPU app in offline mode and pass it the command line from any workunit to see if it works.

Thank you

I've been doing BOINC work without issue for over a year on my Arc A750 (primegrid and Einstein mostly)
If you can point me to a guide on how to proceed, I can test

You can just download https://sech.me/boinc/Amicable/download/Amicable_OpenCL_v_3_06.exe and then run it with command line

/from 2*5*7*19*259777759 /to 2*5*7*19*259875541 /task_size 500185564895

. If it runs and finishes without errors, then it should work fine on Intel ARC.

Thank you, I'll give it a try and post here

Now I remember why I disabled it. Intel has many CPUs with integrated graphics (which is not Intel ARC), and their driver quality is very bad, they never worked. Maybe they improved today.

Correct, also Intel iGPU impacts CPU performance, but Primegrid has implemented support for the discrete Intel GPU (ARC 380/750/770) while not allowing the iGPU to process any WU.
So maybe there's an easy way to allow it for amicable ?

Maybe I could find a set of parameters for plan class that would filter out integrated GPUs: https://boinc.berkeley.edu/trac/wiki/AppPlanSpec#GPUApps
For example, I could limit min_gpu_ram_mb to 5 GB for Intel GPUs, min_gpu_peak_speed to some value that Intel ARC GPUs pass and integrated GPUs don't pass. I'd like to know how exactly PrimeGrid did this.

I've asked ;D

Thanks! I will try to remove the "Intel bad" check from my code tomorrow, and use the similar config.

I have enabled Intel ARC GPUs with the new GPU application version (3.07). If you have GPU tasks enabled on your end, you should be getting tasks now.

Thank you

i get the following;

ARC A750

375 Amicable Numbers 3/3/2024 7:16:16 PM Not requesting tasks: don't need (CPU: job cache full; Intel GPU: GPUs not usable)

I've reset the project and I still get the same message

There's no "use Intel GPU" on the preference page;
https://sech.me/boinc/Amicable/prefs.php?subset=project

I entered the wrong name for Intel GPUs in the plan class, it should be fixed now.

I've reset the project but still get the same error.

Some info from the Primegrid Dev;

the important line you need to avoid IntelGPU HD

They need an app with opencl_intel_gpu_intelarc or perhaps change it to opencl_intel_gpu plan_class

I've changed the plan class to:

	<plan_class>
		<name>opencl_intel_gpu</name>
		<opencl/>
		<gpu_type>intel</gpu_type>
		<host_summary_regex>Arc</host_summary_regex>

		<gpu_ram_used_mb>800</gpu_ram_used_mb>
		<cpu_frac>0.0001</cpu_frac>
	</plan_class>

This regex is very simple and it should match your host.

Thank you, I'll check in a few minutes.
I saw you updated the preference page, thank you.

Should I reset the project before attempting to get new tasks ?

I've set to no cache so it should look for work pretty regularly

the primegrid Devs have confirmed your plan_class should work..
however, I still have the same message;

Not requesting tasks: don't need (CPU: job cache full; Intel GPU: GPUs not usable)

I had reset the project before to make sure I got new config files, and use Intel GPU is selected in my preferences
