Even when I click on the image, it is still a small thumbnail 😀.
May be you would like to unhide your hosts?

Should be solved now.
Happy holidays!

Happy holidays for you too! And for all other aarch64 (armv8) testers as well!

The 4GB Jetson Nano running Ubuntu 20.04 LTS was my first ARM board to actually complete an Asteroids WU -as well as an Einstein CPU WU, have to download the custom app by Gaurav Khanna to obtain Einstein GPU apps for ARM/Linux.

Yes, I see that my Jetson SoC's aren't going to be able to run the project. Still stuck on glibc 2.27 because of the distro.
Shame. At least they work at Einstein.


You might want to switch to Armbian as OS on the Jetsons, they offer a much more recent version of Linux with a far later version of glibc. Alternatively, you can sell the Jetsons and buy new Orins in a few months.
Note: When you upgrade your Jetsons to Ubuntu 20.04 you will be rewarded with glibc 2.31

I haven't so far as the custom Einstein gpu app doesn't run on anything but the 18.04 distro. I don't have the source code to recompile it under 20.04.

[Edit]
Hmmm, your link mentions maintaining gcc-8 compatibility as that is what the custom Einstein gpu app needs. But that is a lot of work to do the upgrade. Will have to think about it.


I'll try to test it on my Jetson Nano with Ubuntu 20.04 for you! So far it is running two Asteroids WUs at the same time, along with its usual WEP-M+2 work. Second Asteroids WU goes a lot quicker, 77.316% in a mere 1: 20hr before it was paused.
Update: Yes, I managed to download Einstein WUs too, and one is running. Should be ready in about 2:40 hours, but I'm off to bed now: 03:54 local time.

Currently running five aarch64 (armv8) WU's:

On an 4GB Odroid-N2+ , running Armbian [5.10.123-meson64|libc 2.35];
on a 8GB Raspberry CM4, running Raspberry Pi OS (Debian GNU/Linux 11 (bullseye) [5.15.32-v8+|libc 2.31]);
on a 4GB Rock Pi-4B+, running Armbian [5.15.76-rockchip64|libc 2.35];
one on a 4GB Jetson Nano, running Ubuntu 20.04.5 LTS [4.9.201-tegra|libc 2.31];
and the last one on a 8GB Odroid-M1, running Debian 11 (Debian GNU/Linux 11 (bullseye) [5.18.0-odroid-arm64|libc 2.31]).

Hi Georgi,

no these are Boards from ASUS with RK3399 (2x Cortex-A72 and 4x Cortex-A53) and 2 or 4 GB RAM.

Greetings


The name is Tinker Board 2/Tinker Board 2S. I have a Rock Pi 4B+ with a likewise RK3399 and 4GB RAM and the WU will take 7 hours (as announced after download).

I downloaded a Asteroids WU on my Rock Pi 4B+ as it has the most elaborate cooling (80mm + 40mm fan plus very big heatsink combo) and it has announced a zeven-day computation period with ten-day deadline.

After a very short time the app aborted, and this error appeared in the log:
Error: Number of lc points is greater than POINTS_MAX = 1000

disregard


Why disregard? I have an Odroid-N2+, four Raspberry Pi 4's, A Rock Pi 4B+, two Nvidia Jetson Nano's, an Odroid-M1 and two Raspberry Pi 3's running a 64-bit Linux/Arm OS.

By the looks of it:
Raspberry Pi running Raspian Linux (arm) 102.10
Raspberry Pi running Raspian Linux (armv6l) 102.10

There isn't a armv8 application yet for Raspberry Pi 4's running 64-bit Raspberry Pi OS.
Can we please get one?

I would ditch the Zero's, as they are using an ARM11 CPU (ARMv6 instruction set), and install Buster on the RPI3's too.

Post:
are there any plans to support this? Currently no projects seem to support, what is a standard build of CentOS 7 on RPI3, which is identified as "armv7l-unknown-linux-gnueabihf"


You can connect with any Linux/ARM to all projects that have 32-bit and/or 64-bit ARM applications -your board needs to support ARM64 in case of the latter.
There are no special applications for CentOS. If you have a RPI3 on CentOS, just install BOINC and look out for projects with Linux/ARM applications -such as Asteroids@home.
If you have chosen 64-bit CentOS for your RPI3, add this to your cc_config.xml (using a plain text editor)
<options>
   <alt_platform>arm-unknown-linux-gnueabihf</alt_platform>
</options>

You should try MilkyWay@Home, the only project that actually asks for double precision GPUs -and will exclude all others from participating.

Post:
Considering the fact that the Raspberry Foundation has brought out no less than three new iterations of the Pi since your present model B+, each time at roughly the same cost: Can't you upgrade to the Pi 4, even if it is the 1 GB version? You will have a 64-bit quad-core ARM Cortex-A72, capable of so much more than the by now ancient 32-bit single core ARM11 that you are presently using.
