[ANN][GAP] Gapcoin - Prime Gap Search - New Math Algo - CPU / GPU - Zero Premine

[Pedro666]

Hi, Guys.
I'm actually an iOS developer, but for experiment decided to create a cuda miner in free time. I rewrite mpz's powmod function for cuda and ran it on my old 9600gt. The first results are 12x times faster then on CPU. On new cards we can get really great result.
The second step is to integrate into the miner. But as my video card on my pc, I have to compile the miner for windows. Which is quite difficult for me, as my usual development environment is Mac with Xcode.

So the question is: does someone have build ready visual studio solution with built libraries for windows? Or just explain how do you compile the miner on windows?

Trying to compile the miner for windows is not something on which I want to spend my time, so if no one responses, I will install ubuntu on my pc.

For windows compilation I use MinGW and MSYS.
This thread has a good explanation about the basic setup: https://bitcointalk.org/index.php?topic=149479.0

It works! Thanks!

@j0nn9, is it possible to realize improvement of dcct for the GPU-miner?

I'm not sure whether it is possible.

I've been trying the last few days to get something running,
but since dcct's improvements are for the sieve, which currently runs on the cpu,
I didn't got a solution which was really faster than the current gpu miner.

The problem is, that Gapcoin's sieve probably can't be ported to the gpu without a huge speed reduction
I already tried only scanning the sieve on the gpu, splitting it in several pieces for each gpu thread,
but that reduced the overall speed about 1000x

it's just so that Memory is a bottleneck on the gpu.

But I'm not yet out of ideas

Anyone able to compile this for Windows and would share a link please, thanks.

Would be nice to see these links in the OP.. maybe you could add some links next to the accomplished bounties

Seems like the dcct cpu miner performs better versus the gpu miner. I can't get either gpu or cpu miner to use stratum, they both get a handle error. But the longpoll/getwork works fine for both.

Yep but he said that the method he is using wouldn't really work on GPUs - guess that thought crossed a few minds

I'm just mining this for fun...lol....

An old AMD Phenom II x6 1055t I'm using does 25%~50% better than my AMD HD7970...lol

Seems like the gpu miner isn't fully optimized yet and still uses a good amount of the cpu also.

I think lots of gpu speed issues may be cpu related, look at gpu usage to see if there's a bottleneck. Hopefully someone can improve on the cpu part of the gpu miner, even small improvements would likely bump speeds.

The GPU usage is between 80%~95% fluctuations and the cpu is around 50% usage. I'm mining the AMD cpu on a different rig than the gpu, just to see how they both do. The the gpu is teamed with a Core i5. Hopefully, the gpu miner will be optimized in the near. But for now, cpu mining is better at the moment...

Increased frequency in VGA possible is achieved greater speed. Two vga card R9 280X (300 000pps) + 7970 (330 000pps) (frequencies 1150/1500) , and one R9270x - 200 000 pps (frequencies 1170/1400).

Tried 1150/1500 on the HD7970 and not much of a boost in performance, about 276k....

I get ~350k with the AMD Phenom II x6 1055t.

I just started mining this today. Is it better to pool mine or solo mine at the moment? I'm pool mining at the moment.

Stay on pool...

i5-4460 runs at roughly 400k
i7-4770 at 800k
i7-920 at 400k

Using GPUs is wasted power.

Are those on the dcct cpu miner? I figure that the gpu miner isn't too efficient at the moment, but I just want to try it out anyways. If the gpu miner could do ~1,600k or higher on a 280x/HD7970, then it would be worth it.

This is a COOL coin. 

More people are learning of it.

I knew it was a winner from the beginning.

[q327K091]

very powerful concept/coin indeed, not sure about now, but you could have entered AWS with n instances for few days and accumulate, it is now going to get much tougher, and in time much much more tougher, this coin if it continues has potential of seriously disrupting cryptology research (if it reaches certain scale) please look up concept of "rainbow tables"

from the economic perspective you have to be fool to sell right now, this in general applies to all crypto currencies across the board, you all have no idea (many do joking a bit) what you have on your hands.

have a great weekend

Is there a chance that this list will be updated with the latest miners: dcct cpu and the gpu miner?

I get 350k pps with an AMD Phenom II x6 1055t at stock clocks and 250k~275k with an AMD HD7970 at 1150/1500 clocks.

I agree that you need to upgrade. how to do it?

[ffmad]

there is an IRC channel for this coin ?  

interesting concept
