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

[Aleh777]

Difficulty going down, miners shutting off aws instances. GPU miner still unlikely

And you only have to talk...Where can I download the GPU miner?

Do not talk nonsense...

?? He said that the GPU miner is unlikely, that means NO GPU miner.

Still no one wants to sell me 10k GAP for 20k sat instead of dumping on the exchange ? That's weird.

No one is taking you for serious it seems, help other miners out, place the order on polo.

I believe the offer is to flush out anyone with high performance miner (notice I didn't mention general purpose stream processors).

perfect timing on my part, now the only thing that has to happen is GPU miner

[j0nn9]

Hi there,

just wanted to inform you, that I started working on a GPU miner.
At the moment i can't say how long it will take.

Just playing around with eXtremal's (madMAx's) code.
Till now, the results are pretty promising:
On a R9 280 the fermat test gives a 30x - 40x speed increase in comparison to a single cpu core and gmp.

The sieve in Gapcoin only runs about 2-3% of the time,
so at the moment I will only port the primality testing to the GPU.

And of course I will open source it, once it's finished.


Thanks for all your great support so far,
I will keep you informed about the process.

Why is there only one pool to mine Gap ?

doesn't that affect the mining process or the blockchain integrity ?

Yes, it's not a perfect situation,
but consider Gapcoin is only two weeks old.

More pools will follow.

Does anyone have a list of pools they like to use, or know of pools that are reliable and you think they would like to add/are capable of adding this coin?

I'll email them, asking to add this coin, all you have to do is post the name of the pool/operator so I can google/search for it.

I already asked ypool, but they currently don't have the ability to add a new coin.

A scorpion asks a frog to carry him over a river. The frog is afraid of being stung during the trip, but the scorpion argues that if it stung the frog, both would sink and the scorpion would drown. The frog agrees and begins carrying the scorpion, but midway across the river the scorpion does indeed sting the frog, dooming them both. When asked why, the scorpion points out that this is its nature.

tl;dr: Dumpers gonna dump

Atrides http://dwarfpool.com/ or http://1gh.com/

maybe if someone asks, they can add Gapcoin.

I asked http://1gh.com add gapcoin through twitter, and http://suchpool.pw but no answer.

[fronti]

Just the short question..
is there already a p2pool ready for GAP? so that I can setup one?

[Damadegyptian]

I contacted Suchpool.pw with a request to add this coin. Would be nice to see a couple more pools pop up.

nonce-pool doesn't have more than 50% nethash. Don't worry.

[bsunau7]

Anyone else been keeping an eye on testnet?

Difficulty is rising pretty fast, which means some serious mining from a very small base is happening.

Could very well be the dev working on a GPU miner.  He mentioned it a few posts up.

I see a difficulty below 17. Thats <100k pps total.

Let me show you how to optimize the miner:

My I7-4770k with 8 threads, stock-miner:
pps: 31821 / 31160  10g/h 4473 / 3429  15g/h 0 / 0

Now go on and build your own libgmp from source. When done, run the tune utility for optimum results. Copy your final libgmp.so.10 to /usr/local/lib/.

Now we're at:
pps: 34039 / 34041  10g/h 6077 / 4479  15g/h 0 / 0

Optimizing sieve size:
open src/main.cpp

line 252:
  1048576);

to
   8 * 1048576);


and line 256
  500000);

to
  15000000);

make sure to also change the shift, otherwise you wont be able to submit most blocks! You could specify it on command line, but this is safer:

line 128:
  uint16_t shift = (opts->has_shift() ?  atoi(opts->get_shift().c_str()) : 20);

change to:
  uint16_t shift = (opts->has_shift() ?  atoi(opts->get_shift().c_str()) : 23);


Now its mining at
pps: 38276 / 37068  10g/h 5156 / 5265  15g/h 0 / 0


Lets also add the tuning for Haswell AVX2:
open Makefile and set

OTFLAGS   = -march=core-avx2 -mtune=core-avx2 -O3
(if you have a haswell, of cause)

Results:
pps: 39691 / 39553  10g/h 6059 / 5635  15g/h 0 / 0
