I used to take part in a lot of distributed computing projects but eventually stopped, as I felt less inclined to leave my PC thundering away 24/7.

But now, with the low power required for a R-Pi I am planning to get one and run BOINC 24/7 again

I am not sure any of the BOINC projects will run on linux ARM (yet).

I love the cryptography ones

Could I put in a request for someone at Broadcom to write a Large Integer Library for the GPU? Something that could multiply two long decimal strings using parallel multiply  and add would be fairly simple, and have educational uses.

I don't know why someone at Broadcom should do this.

There should be a large community somewhere in the Internet which is interested in porting all kind of math libraries to gpu supporting modules.

Maybe the library you need is already available?

I don`t have access to the Videocore manual,  so I rely on  the goodwill of people inside BROADCOM, if they think it would be useful.

I am assuming that Linux libraries would be community driven, but to fully unlock the power of the GPU needs a simple, but proprietary, SIMD interface.

Unfortunately the word simple in that sentence really doesn't apply. Passing off any sort of data to the GPU, processing it using vector code, and getting the results back isn't simple. I've been looking at it, it's a big job.

Thanks anyway, I thought it was worth asking.

I thought I would revive this thread given my interest in the subject.

Does anyone know if there has been any head way on getting the RPi's to do distrobuted computing?

BOINC runs well (do a search) , but the Pi isn't exactly a
powerhouse , nor does it have an exceptional MIPS/watt or
MIPS/dollar ratio.
Also not all projects seem interested to support ARMv6
(used by the Pi and over 5 years old AFAIK) and
are focusing on ARMv7 , which makes sense.

Hi!

As for BOINC, Albert@Home (the Beta Test project for Einstein@Home) is now supporting the Raspi

http://albert.phys.uwm.edu

There are already a few RasPis but more testers would always be a good thing.

Some projects are now aiming at Android smartphones and tablets, and there are still a lot of smart phones sold in the budget market system that still have ARMv6 CPUs. So there is hope for some more Raspi-suporting BOINC projects.

Cheers
HBE

Thanks to the excellent work done by Daniel Carrion http://burdeview.blogspot.com.au/p/rasp ... eated.html and project admins, in the past few weeks I have sucessfully run and completed Albert (1 task), Milkyway (2 tasks), WUProp (133 tasks) & Oproject (1,931 tasks) on my 256MB Model B RPi using Raspbian & BOINC 7.0.27.
Daniel has details on his blog (above).
