dnetc on the Raspberry Pi


Morning all,

Has anyone else tried the d.net client on a Raspberry Pi? For those who 
don't know what one of those is, it is a credit card sized ARM based linux 
box that you can get for under 30quid delivered here in the UK. It has a 
700MHz ARM CPU, 256MB of RAM, 2 USB ports, 10/100 ethernet and HMDI 
graphics and uses an SD card for storage.

Anyway, I've put dnetc on it and it's happily crunching away at the rc5-72 
project at around 770kkeys/s. Nothing special in terms of keyrate but it 
wasn't really designed for performance.

One interesting point to note is that from what I've read the RasPi has a 
very powerful GPU on it and I was wondering if someone a lot brighter than 
me has considered doing an rc5 core for it that makes full use of the GPU?

Hi Paul,

Development tools for VideoCore are only available from Broadcom under NDA. :/

Perhaps someone better placed than I can tell if we are able to port
our GPU code to OpenGL.

Cheers,
Mike

Hi Paul,

I'm not sure if you are aware but there is already a GPU client for Linux
you can find in the download section here

I know there is for some x86 CPU and GPU combinations but as mentioned in 
my OP the Raspbery Pi has an ARM CPU and neither of the two clients listed 
there for ARM have GPU acceleration code in them.
