Hi volunteers,

I am trying to get Asteroids@home running on my Pi Kubernetes Cluster. The Pis are running Raspberry Pi OS (64 bit)
Project response "Message from server: This project doesn't support computers of type aarch64-unknown-linux-gnu"

BOINC Client starts up like that

I tried with alternative platforms in a custom cc_config:
<alt_platform>arm-unknown-linux-gnueabihf</alt_platform>

but this leads to computation errors:

Any suggestions how to tweak BOINC with an alternative_platform or
is it more likely that Kyong has to recompile something ?

Btw Rosetta, LHC and Einstein are already running well on this cluster.

Cheers

Hi volunteers,

I think I found a solution for my issue.

As stated above I am running BOINC Kubernetes (K3S) cluster in Raspberry Pi 4 models. I build the container image for the pods by myself based on the original boinc/client buildcode on github.

The container image I build had only 64 Bit libraries. Thats why Astroids@Home 32 Bit Application generated "Computation errors". I rebuild the container image and added the needed 32Bit architecture armhf and also the libstdc++6:armhf library. Docker buildfile looks like this now:

FROM arm64v8/ubuntu:rolling

LABEL maintainer="BOINC" \
      description="A lightweight BOINC client on ARMv8 64-bit architecture."

# Global environment settings
ENV BOINC_GUI_RPC_PASSWORD="123" \
    BOINC_REMOTE_HOST="" \
    BOINC_CMD_LINE_OPTIONS="" \
    DEBIAN_FRONTEND=noninteractive

# Copy files
COPY bin/ /usr/bin/

# Configure
WORKDIR /var/lib/boinc

# BOINC RPC port
EXPOSE 12345

# Install (also 32Bit architecture and libraries)
RUN dpkg --add-architecture armhf && apt-get update && apt-get -y upgrade -qq && apt-get install libstdc++6:armhf -y && apt-get install -y --no-install-recommends \
# Install Time Zone Database
        tzdata \
# Install BOINC Client and some tools
    boinc-client tar sed wget && \

# Cleaning up
    apt-get autoremove -y && \
    rm -rf /var/lib/apt/lists/*

CMD ["start-boinc.sh"]

The zipped containerimage grew from ~120MB to 140MB but thats because of the needed 32Bit libraries.

I also added two alternative platforms to the cc_config.xml

<cc_config>
  <options>
  <alt_platform>arm-unknown-linux-gnueabihf</alt_platform>
  <alt_platform>armv7l-unknown-linux-gnueabihf</alt_platform>
  </options>
</cc_config>

Now Asteroids@Home tasks are fetched and processed (btw. also Universe@Home). Yet without any "Computation errors". Looks like each Asteroids@Home task needs about 15h to finish.

I wonder if a task could be finished faster if there would be a 64Bit Asteroids@Home application for arch64-unknown-linux-gnu platform.

Happy Crunching

The current state of apps for the Rpi is summarised in this post from August 2020.

1. The ARMv6 Pi’s all fail (that’s Pi zero and the original Pi).
2. The current app works on Pi2 and up but doesn’t use neon which makes it extremely slow.
3. There isn’t any support for aarch64
