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

[j0nn9]

I get 2.1m pps on my r9 290x on default settings. These seem optimum, as most settings don't seem to change anything. With sieve-size lowering it by about 600kpps if I go up or down.

It runs fine using -t 1 so I figured I could run the cpu miner as well but that caused the GPU to half in speed. Is there any way to run them both or is it a choice of 1 or the other?

You could try to reduce the thread count on the cpu miner.

Sorry, I meant on the cpu miner I ran -t 1 as well, to test it. It still caused the slow down. So to confirm

So both the gpu miner and cpu miner running -t 1 causes the slowdown.

It seams that on your system it's just one or the other,
but I wouldn't generalise it. It probably depends on the actual cpu.

Ok, if yours does not do it, it must be something to do with my PC, I have a few more R9 290x's mining other things that I can try this weekend. Just FYI though, the CPU I am running is an i7 4790K so I don't think it is CPU load here that is affecting it.

I want a better CPU miner send me pm and we can make a good deal.

I want another poll and another exchange, poloniex killing this coin.

Best I've been able to get with a radeon 7970 is between 1,500,000 - 1,700,000 PPS with the following settings:
-g -j 5 -n 4 -w 1000 -i 50000

The flags used above are explained below:

Enable GPU mining:
-g

Stats interval (in the settings above, I have stats printing every 5 seconds):
-j

Number of tests per gap per gpu run:
-n

Number of primes for sieving:
-i

Tried many different values for the -n and -i flags and actually had it around 2,000,000 PPS, but the test/s kept going to 0. I preferred stability so I adjusted the settings to lower the PPS and keep tests/s high.

A few other settings that may have an effect on PPS, just for some quick reference. These can all be seen by running the help command ./gapminer -h:
--work-items (gpu work items - default: 2048)
--queue-size (gpu waiting queue size - note: memory intensive)
--sieve-size (prime sieve size)
--shift (the adder shift)

About the speed: I managed to get around 1,200,000 pps with a single AMD R9 280, that's a 6x speed increase to the previous GPU-Miner.

Thank you the update! 

Do you mind sharing your settings as I am only getting 700k pps with my R9 280x ?

All fine now. I overwrote the "-w 512" setting as I copied an old startfile...

Keep up the good work with this cool science coin!

Hi everybody,

I have an r9 290 amd gpu and am unable to configure my miner settings.  Request you to please share your r9 290 gpu miner or any other gpu miner settings for gapcoin.  I want to mine this coin.

Hi,

first of all you need an account at the pool: http://gap.nonce-pool.com/

Now create a worker: http://gap.nonce-pool.com/index.php?page=account&action=workers

Download and install Install AMD APP SDK v2.9: http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/

Download and unzip the miner: https://github.com/gapcoin/GapMiner/releases/download/gpu-miner-rev3/windows.zip

In the unzipped folder (windows/64) edit start-gapminer.bat
(uncomment the first option and change user.worker and password according to your worker settings at the pool)

Code:

:: choose your preferred mining method:
::
:: getwork
gapminer-gpu.exe -o http://mine3.gap.nonce-pool.com -p 4205 -u user.worker -x password -t 1 --use-gpu -w 512
::
:: stratum
:: gapminer-gpu.exe -o mine3.gap.nonce-pool.com -p 3385 -u user.worker -x password -t 1 --stratum --use-gpu -w 512
::
:: solo mining
:: gapminer-gpu.exe -o 127.0.0.1 -p 31397 -u <rpc user> -x <rpc password> -t 1 --use-gpu -w 512

Start mining by running start-gapminer.bat

hi,

i have registered at the nonce pool, installed the amd app sdk v2.9 n the miner n followed the instructions. but im still getting errors.  i dont know im doing wrong.

[sirlimpy]

And the error says?
