Hello,

on my both odroid - linux systems i got an error after requesting new tasks:


4218 SiDock@home 27.12.2021 20:48:57 [error] Signature verification failed for cmdock-boinc-zcp_job_1.0_aarch64-unknown-linux-gnu.xml
4219 SiDock@home 27.12.2021 20:48:57 [error] Checksum or signature error for cmdock-boinc-zcp_job_1.0_aarch64-unknown-linux-gnu.xml

Has anyone else this problem?

thank you!


Hi everyone,

yes, i have exactly the same problem. The download of the aarch64 application fails because of signature error for the .xml file

Thank You!

Greetings

As far as i know an official ARM app is in the making. But it is not top priority because there are a lot of other things to do right now (like checkpointing).

For the Raspberry there are official cmdock ARM32 linux binaries avalble on gitlab: https://gitlab.com/Jukic/cmdock/-/releases.

I got it to work on my Rasperry Pi 4B : https://www.sidock.si/sidock/show_host_detail.php?hostid=2358 and Raspberry 3B+ https://www.sidock.si/sidock/show_host_detail.php?hostid=8318 . As you can see the computers have credit. I just stopped crunching
because i wait for smaller workunits and/or checkpointing (Runtime of Eprot WUs are up to two days on a Pi 4, Pi 3B+ won´t make the deadline). You have to compile the Boinc wrapper for ARM from official sources and tinker with the app_info.xml and job.xml settings (Anonymous Platform https://boinc.berkeley.edu/wiki/Anonymous_platform and Wrapper https://boinc.berkeley.edu/trac/wiki/WrapperApp) to get it to work.

Or you just wait. :-)

For Mac M1 I don´t know.

I just noticed that the app_info.xml i posted above has a typo. Of course the wrapper executable and the wrapper-job.xml need to have the same filename in the <file_info> and the <app_version> section.

Hello Natalia,

i think i didn't have to specify anything in the cc_config.xml because i used the "Anonymous Platform" which solely relies on the settings in the app_info.xml (https://boinc.berkeley.edu/wiki/Anonymous_platform). This ignores all official patforms as far as i know.

But when i add the project without the app_info.xml i get the error "This project does not support computers of the type "arm-unknown-linux-gnueabihf". Raspberry Pi OS 32-bit is arm-unknown-linux-gnueabihf by default. So i think arm-unknown-linux-gnueabihf is the right platform to specify for a 32bit-ARM (Raspberry Pi / Raspberry Pi OS compatible) client app.

As i remember "RakeSearch for rank 10" had an official app for arm-unknown-linux-gnueabihf as well : https://rake.boincfast.ru/rakesearch/apps.php

P. S. Just in case it helps bulding an offical app : This is my app_info.xml (note that "sidockwrapper" is the BOINC Wrapper compiled from the official BOINC sources on ARM):

What was the runtime before?

Since yesterday we are cruncing on the fifth target: https://www.sidock.si/sidock/forum_thread.php?id=97

Please note that these new workunits can run five times as long as the old WUs, so it seems pretty normal to me. These are just way bigger WUs.

There are so many things to do, but yes, we remember the ARM and aim to make it an official app version.


No problem! No hurry, i can imagine there are a lot of things to do in this young project.

Meanwhile i have managed to get the official cmdock binaries from Marko Jukićs Gitlab to work with the project on my ARMs!

And i have some very good news:

My Raspberry Pi 3 Model B+ (https://www.sidock.si/sidock/show_host_detail.php?hostid=8318) and my Raspberry Pi 4 Model B http://(https://www.sidock.si/sidock/show_host_detail.php?hostid=2358) are producing 100% valid results for a few days now! :-)

Note that you will need good cooling (e.g. large heatsink, better with active cooling) if you choose to run BOINC on single board computers like Raspberry Pi that may not require cooling when only used for light tasks like server etc.!

Cheers and happy crunching

Great to see finally ARM binaries available :)

So it should now be possible to participate in SiDock@home with ARM computers? (as i already asked here: https://www.sidock.si/sidock/forum_thread.php?id=67)

But its still not in the application list. Is it just not high on your to-do list (which is completely understandable - science first) or are there some problems / technical difficulties?

All the best

The challenge is over but nevertheless the Project just reached the 30000 GigaFLOPS mark.

Very impressive. Keep up the good work (admin and crunchers)! :-)

In case this hasen't been asked already: How are the chances of getting an official ARM Version of the CurieMarieDock App? RAM Usage and WU size seem quite suitable for small ARM computers... :-)

With the best of wishes for a happy new year!
