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

It'd be interesting to compare.

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

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.

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. Smiley

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!!

His username Wink

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...

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

Sent PM. Lots of GPU's to test on.

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.

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.

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.
