Here is the Mi Box S host : https://einsteinathome.org/host/12877531

LoL, one step closer to "crunch on every iron" :)))

Crunching on TV now :)))

Next issue.... BOINC waits

Next issue....

BOINC waits for "battery cooling".

But box has no battery at all! So what BOINC waiting for ?....

Yep, wrong programmer assumptions inherited by software itself :)

Android OS (and its AndroidTV flavour) can run on quite different systems (PC emulator included). Some of them definitely will be w/o battery.  Interesting to try BOINC for Android under BlueStacks emulator. Will it be able to start or will be awaiting battery too?...

Anyway luck on my side so far. Trick with very high allowed battery reading worked so host is really crunching now. 2 tasks at time (2 GB memory, 4 cores so perhaps will be hard to get anything better than 2 at once for memory-hungry E@h tasks). ~40% done, hope will get first completions till evening.

Box itself is warm. Definitely warmer than surrounding but not as hot as charging phone.

 

EDIT: IR thermometer says 35,5C at box surface. 

 

EDIT2: Said - done. Tried BOINC for Android (this time Google Play version) under BlueStacks emulator.

Well, it's not complaining about battery temp there.... but waiting to be plugged in (!)

Хрен редьки не слаще :)

Can be circumvented though allowing crunching on battery (battery doesn't exist, but who cares :) ).

 

Pity can't test crunching itself there cause E@h doesn't supply science app for Android on x86 hardware...

First 2 valid

First 2 valid results

 

Peak working set size (MB):131.19

Peak swap size (MB):161.14

With such numbers could try to load more cores...

yep, but I saw only BRP on Android so far.

Better to look here: https://einsteinathome.org/apps.php

Only Android on ARM supported (that's quite OK, cause x86 can use other OSes with easy).

Yes but I am always hopeful

Raspberry Pi OS based on

Raspberry Pi OS based on Debian bullseye released. Debian released bullseye on the 14th of August but its taken the Raspberry Pi foundation a while to get it working on the Pi. The official announcement is HERE

I've installed it on one Pi4 8GB model. Its This host. The benchmarks say its a bit faster but that might be due to the newer GLIBC library its using. Its running Einstein work at the moment.

If you have a Pi4 with C0T stepping you are supposed to get a higher boost speed of 1.8GHz. The B0T stepping will boost to 1.5GHz, unless you've overclocked it. You'll have to look at the SoC for the last 3 characters to find out what you've got. They did mention the 8GB model gets it, even though mine say they are B0T stepping.

Thank you very much for your post, I was hesitant to update my own Pi's but will now do so knowing it works without causing any major problems.

The only problems I had on the clean install and applying my usual instructions was:

1. iptables is not supplied automatically but there is a package iptables in the Debian repo. If you don't use iptables then no need to install it.

2. The boinc-client package (7.16.16) in the Debian repo, the service is disabled by default so you have to manually start it or enable the service if you want it to start automatically. Use "sudo systemctl enable boinc-client" to enable it.

I run my Pis headless (no screen or keyboard) so I installed the arm64 "lite" version of Raspberry Pi OS. There have been some changes to the desktop which might effect people who use a screen and keyboard on their Pi.
