Re: [beagleboard] Hash rate

[Eric Fort]

Not sure of the hash rate of the beaglebone black, but based upon what I've read recently the only bitcoin mining that makes economic sense anymore is based upon custom hardware, either FPGA or ASIC.

In light of the above there is a cape in development for the original beaglebone that contains a spartan 6 fpga and hits the lower end of economically viable bitcoin mining rigs.  Look for the Logi-Bone To be released soon.

Hi All .....can somebody please tel me the hash rate of the new Beaglebone Black . I am considering use it for bitcoin mining. Also could two Beaglebones be connected together to provide greater hashing rates.
many thanks

Is the hash rate calculates by hash/hour or hash per watt-hour? Even if the bone is slower than the high end hardware, it may win on operation cost.

Don't know exactly how fast it would be, but the BeagleBones have a PRU,

which has two processors, so effectively you have three processors, two

of which (the PRUs) are RISC processors. They only have limited memory

and are really designed for IO processing, but they might be usable.

 

The original BeagleBoard chips have a DSP built in, which might be

better.

 

The only real way to find out is to read the TRMs for the chips, and

then try it.

 

Connecting two(or more) together might help, but you would have to work

out the rate at which you would need to transfer date between them and

see where your bottlenecks would be.

you would likely not end up transferring any data between units, instead each would work on it's own block, thus 2 units being exactly 2x as fast, 3 - 3x, ad infintium.  guessing this is not an application where the pru would help much.  Use an fpga board, they'll most likely be under 100 usd.

Heh i was curious about this myself, and thought i might try to set it up, but never got around to it.

So now the question is how long before someone will workout how to use the powerVR graphics . . .

Hi,

I'm running cpuminer on the BBB on the original Angstrom distro.  My average hash rate is about 520 khash/s, but it does vary up and down a little bit.  It's pretty cool because there's absolutely no noise at all.  Just plug in the power, USB and network, start the miner and forget about it.  I normally start it with nohup...&.  I've ordered another BBB which will get the same treatment.

Good luck,

Vaughn
