I'm running BOINC on a custom single board computer with an ARM64 processor. I'm having trouble getting tasks from projects because it claims my computer isn't supported. For example, I received the message: "07-Feb-2023 04:43:10 [Universe@Home] This project doesn't support computers of type aarch64-poky-linux". Is there a way to tell a project that you are running some linux machine with an arm64 architecture?

I'm running BOINC on a custom single board computer with an ARM64 processor. I'm having trouble getting tasks from projects because it claims my computer isn't supported. For example, I received the message: "07-Feb-2023 04:43:10 [Universe@Home] This project doesn't support computers of type aarch64-poky-linux". Is there a way to tell a project that you are running some linux machine with an arm64 architecture?

You may be running Linux but many projects do not support the arm64architecture. There SHOULD be information about this on the individual project pages but it can be hard work tracking it down on some. CPDN doesn't currently support it. Other projects I can't remember. I have vague memories of someone posting a link to which projects support which architecture If I find it before anyone else, I will post it.

There SHOULD be information about this on the individual project pages but it can be hard work tracking it down on some.

Like on CPDN who now have their own front-end, yes. But the standard BOINC front-end has the Applications page (depending on BOINC server version under Computing, Server, or from the front page) which is automatically populated by the applications that the project supports. In case of CPDN this is at https://www.cpdn.org/apps.php, but just adding /apps.php on any project's URL should get you there for that project. Then you can see which platforms are supported and in some cases it shows the actual platform application name used (like here: https://www.cosmologyathome.org/apps.php), but otherwise a careful checking of the client_state.xml file will net you that as well.

Separating post as I hit limit on URLs posted.

So, Universe@Home has these applications: https://universeathome.pl/universe/apps.php
It does support some ARM CPUs. In which case you could play around with https://boinc.berkeley.edu/wiki/Client_configuration#Options the alt_platform option in cc_config.xml, which will be an alternative with which platform BOINC asks for work from the project:

<cc_config>
<log_flags>
</log_flags>
<options>
<alt_platform>arm-android-linux-gnu</alt_platform>
</options>
</cc_config>

These are for android_arm_pie Universe BHspin v2 v0.21, so make sure you have the correct applications set in the project preferences at https://universeathome.pl/universe/prefs.php?subset=project

You can run the armhf architecture on your SoC if you have the capility of adding that architecture from your distro.

This is what I do for my RPi 3 and 4.

sudo dpkg --add-architecture armhf
sudo apt update
sudo apt install libstdc++6:armhf libgomp1:armhf libboinc7:armhf
sudo reboot

Additionally you have to add alternate platform identifier to your cc_config.xml file:

<cc_config>
<options>
<alt_platform>arm-unknown-linux-gnueabihf</alt_platform>
</options>
</cc_config>

Thanks. This suggestion worked for me. I added aarch64-unknown-linux-gnu as an alt_platform option in the cc_config.xml. I was then able to complete tasks for Asteroids. Unfortunately, Universe still does not support this platform but that's ok.

From my android phone,

World community grid, Einstein, Universe and Rosetta are the only 4 projects supporting arm A50 (efficiency) series cores.

If you're running an A70 series (performance) core, results might be different.

Universe usually has the most WUs, but occasionally have months of nothing.

WCG is second,

third Einstein and Rosetta. These 2 only very sporadically have WUs for arm.
