Message 1747728 - Posted: 8 Dec 2015, 21:04:42 UTC

Is there any plans to support the Raspberry Pi directly from BOINC Manager?

Currently, you can connect the BOINC Manager to SETI@Home and download a binary ass suggested by a blog site such as
http://www.element14.com/community/community/raspberry-pi/raspberrypi2/blog/2015/05/20/setihome-boinc-on-raspbian-for-raspberry-pi-2
This seems to work, but it does report a problem with the xml configuration file.

The new (Debian) Raspbian Jessie has a repository object (package) called boinc-app-seti (currently version 7.28~svn2633-3+rpi1, with file setiathome_v7. This completes with a work unit result that is rejected.

Thanks.

Yes, It is testing at Seti Beta, I fixed the app and had the fixes applied to the Seti source, (as well as the Debian source), and had it released there:

Seti Beta applications

the app you're running doesn't have those fixes applied, vfp_ChirpData and neon_ChirpData aren't compatible with Linux hardfloat,
you need 7.28_svn2858 as a minimum:

Claggy -

I've run the app from Seti Beta. If the work units are similar size, it is faster than the one I compiled using your instructions from the message boards. How do I download and build the newer one for the Raspberry Pi? Or can I copy the app from my Seti Beta folder to the Seti folder and edit the app_info file?

Yes you can provided it has low enough inconclusives rate on beta.

I was able to get seti going on a Pi2 by installing boinc and boinc-app-seti with apt-get. If I just installed boinc then tried to use project seti without installing the boinc-app-seti it never got any work to do. Steps that worked for me on a Jessie image:

sudo apt-get update
sudo apt-get install boinc
sudo apt-get install boinc-app-seti
boincmgr

So any way to fix it, or just wait around?

Yes, r3305 broke the compilation, get an earlier revision than that, ie

svn checkout https://setisvn.ssl.berkeley.edu/svn/seti_boinc@3304 seti_boinc3304

https://setisvn.ssl.berkeley.edu/trac/changeset/3305

https://setisvn.ssl.berkeley.edu/trac/log/seti_boinc/client?rev=3316

I'm in the process of emailing Eric.

Thanks. The compilation still fails part way through, but it had built seti_boinc. I don't have the graphics pre-reqs. It has completed a few WUs and they have been validated. Here is one:

I also have rev3304 built, compilation here normally fails in test tools here,

Been running rev 3304 in an offline bench with a number of test Wu's, and online at Seti Beta:

yesterday builded latest rev from svn - need to add one minssing include there - for both PIs
used native in march, mcpu and mtune, hard float , fast math and fpu is neon-vfpv4 for PI 2, vfp for PI

builds are on lunatics website, use app info xml for usage.
now running successfully on mine PIs (have both of them)


They in restricted area currently so public can not access.
If you sure they work OK worth to move them to publicly available area.

What about new Raspberry Pi 3? It's more interesting device.

It would be faster than the existing units, but as a crunching device the Raspberry Pi doesn't make much sense to me. It's just not designed with that sort of work in mind.
Given the time they take to crunch numbers, they actually use more power than current PC systems.


Phoronix Raspberry Pi comparison.

Grant:

Don't get me wrong, I like the technical report that compares different systems.

I have a couple of thoughts:

1. some system has to take the bottom rung of the performance ladder.
2. sometimes running these projects mean that you have to use what you have available.
3. maybe we could suggest optimum projects for the weaker machines, like the raspberry pi

In the "SETI Classic" days, I had access to some "broken" laptop computers that we're one step away form the recycling center. These were mostly slow "Intel Celeron" based machines and had a range of defects such as cracked cases and broken screens. "Boot and Run" was a major "Goal Achieved" statement. In the end, they headed out for the recycling center, but there could be one or two that made a new life in a place where computers were just not happening.

Is it worth while? Of course it is. .. but if you're making a "purpose built" processing farm, there might be better choices.

I would encourage anyone to use whatever system they have to look into the concepts of the idea of sharing their resources with projects such as this.

Cheers.
