About licenses:

We don't have a clear plan but we have some ideas. I'm going to present the forum with them and would like to get some feedback.

But one thing is clear: we will only accept XPMs as a payment.

I already know that Primecoin GPU mining works, the question is how much faster is AMD's 7970 vs Intel's Core i7-4770K (using AVX2 instructions with fixed precision at compile time).

Payment address and pricing please, I need to off-load some of these Primecoins.

Someone could do an analysis of the origin primes and block headers used to produce them to create a miner signature. It'd be a fun weekend project - spot the GPU miner.

For our miner it's pretty easy - it produces huge 'nonce' values.

Just checked one of your blocks: https://coinplorer.com/XPM/Blocks/b555507989f71ba87263e62786783de1592d0ead0b8c45eb930e10ec384f7666
...
Nonce: 744,198,326
...
Are you really using 23#? EDIT: looks more like 17#, my bad.
I've always thought that you could speed up any cpu miner by offloading the hash search to the GPU.

Supercomputing claims to have an nvidia primecoin gpu miner, which he never released AFAIK...

You can clearly see his blocks on the blockchain if you know what to look for.

what do we have to look for? Roll Eyes

Well, I've read Dave Andersen's work on riecoin, and I'm guessing it would apply to xpm as well. I think it's fairly advanced math, for most people to catch on. (me included)

EDIT: oh man, not a single block since yesterday :p getting anxious. The guy with the g1610 got 2 blocks and me with an i7 zilch, nada xD
Tough luck eh.

His/her RIC blocks were obvious, but that may not be the case with XPM. I don't know enough about XPM to say. And, at this point, most of the RIC search strategies have converged to the point where it's harder to distinguish some of the miners.

If you are a solo miner, it is trivial to leave a signature using the Coinbase transaction if you wanted to. But if you are using a pool miner, you can use the double SHA-256 output to leave a signature at the expense of a slight loss in mining performance.

Hi primeGPU,
I also want to test and donate.I have various GPU's - 6770/6870/6990/5870/5990/7850 Linux/WIN7 x64.

What speed increase does a 7970 offer compared with a, say, 4core 2 year old PC (64bit) ?

~50x when comparing to i7-920

Please explain how you reached such a bold conclusion. The AMD Radeon 7xxx series is known for having weak 32-bit integer multiply units. Also, what is the point of this software testing exercise?

7970/280X has 1.4x the 32bit mul throughput than a GTX 780, what exactly do you mean by weak? Also it costs only a fraction, maybe you shouldn't have ignored AMD so much Wink

EDIT: Anybody know how much a license is? Didn't find any numbers...

Im testing the GPUminer from primeGPU.

This miner works! I got a block in less than 6 hours with 2 x r9 280x + 1 x 7950!!

3 blocks already. G1610 is clearly superior ;=)

stabilized around 250ish...with an occasional jump to 16-27.

let's see how long this will keep on running before crashed again.

@primeGPU

What is your set price to obtain the license key?

You can send to me the price along with the payment address (BTC or Primecoin).
