1) Message boards : Questions and problems : boinctui on pi zero - calculations fail (Message 102714)

Post:
Thanks for the advice. I'm running Rasbian Lite, so there is no desktop and i'm just SSHing in to the command line, which is why i'm using boinctui. I've disabled the swap as you suggest, I don't really want it writing to the card any more than it has to, i've experience in the past of programs destroying sd cards very rapidly by continuously writing out logs to them.

Running top, I can see boinc using about 98% cpu and 19% ram, so hopefully thats ok. Is there a way to tell how much the SD card is being used?

the einstein tasks don't seem to be using a lot of ram at all, all things considered. If it is using the SD card much, maybe setting up a little ram drive for it to run in might be possible. Do einstein tasks generally write to the drive a lot?

Yes! thats done it. I installed Jessie lite and an Einstein task is now happily running (but rather slowly of course) .

https://einsteinathome.org/task/1062254365

I'll have to wait and see if its completes correctly, but its running at least which it wasn't before.

Thanks for all your help.

ok thanks everyone for the help here.

I believe Einstein@home does support the PI zero, at least i've seen seen a few anecdotes of people running it successfully.

I wonder if i'm just using too new a version of Raspbian, and the Einstein binary isn't compiled for it.

It seems like this problem:

Perhaps I should try installing Jessie. I'll give that a go and report back.

Thanks Dave, I think there isn't a log file. I tried using find as below:

sudo find / -name "stdout*"

and this was all that turned up:

/usr/share/man/man3/stdout.3.gz
/run/systemd/journal/stdout
/home/pi/stdoutgpudetect.txt
/var/lib/boinc-client/stdoutgpudetect.txt
/dev/stdout

The thread you linked to suggested there might not be a log file and it may be outputting to system journal. So here is a dump produced with the below command:

journalctl --unit=boinc-client

5) Message boards : Questions and problems : boinctui on pi zero - calculations fail (Message 102666)
Posted 23 Jan 2021 by deepfried12
Post:
The hardware is a raspberry pi Zero running Raspbian Buster armv61
Using boinctui headless over ssh, installed from apt repository
boinc client manager version 2.5.0

boinctui runs ok, and projects can be added, they fetch tasks but the calculation completes in about 1 second (clearly some sort of failure) and then there is a message about no output file.

I've tried reinstalling boinctui and boinc-client, i've tried running with and without sudo.

these are a couple of the projects with this behaviour which I think should work:

LHC@home
Einstein@home

i've tried to find a log file but not had much luck, not really sure what i'm looking for.
