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

[smoothdoger]

Hi there,

II know I said next week, but i managed to build some experimental gpu miner binaries .
I created a new release which includes the stratum changes from nonce-pool,
and some bug fixes regarding the device selection.

But still, the binaries and source code are very experimental!

All binaries are linked against AMD APP SDK v2.9
You can get it here: http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/

the most other dependent libraries are linked static.

Windows: https://github.com/gapcoin/GapMiner/releases/download/experimental-binaries/windows.zip
Linux: https://github.com/gapcoin/GapMiner/releases/download/experimental-binaries/linux.zip

thank you for this

[muchoman]

Stratum does not connect.

[qwep]

why involves only one GPU

why involves only one GPU

You have to use one instance per gpu.
Use --gpu-dev <id>, to select the right one.

hi guys, can you please post a sample gapcoin.conf please?

also, has anyone with a radeon 270x tried the gpu miner? if yes, care to share your results?

Hi a line to start 2kart you can put

[PorcoRosso]

CPU load 100% in GPU miner =(

i get the following when running gpu miner with stratum(both 32&64):

Cant actually involve more than 1 card a rig , even with this option :
--gpu-dev 0,1,2,3,4

Yes, it needs powerful CPU for multiple gpus.

One less item on my to-do list for this weekend now that you've released a GPU based miner.  

Sorry if I missed something, but how do you configure the miner to run on testnet? I received too many stale submissions followed by the miner hanging. Please see the log file below:

Yes Ive tried so ,and suppose to work but the speeds are different for each card ...

Which cpu do you have on a farm?

This seems to be normal for an optimized miner.

The miner does not stop mining the sieve until the original one is verified by a slow  mpz_nextprime() call.  When your miner is significantly faster than the PoW function you tend to find lots of shares before the PoW can stop the sieve from mining.

Sorry for another post, card 0 is a 280x and only using around 80-90% of gpu...   card 1 is a 290 and sits at 100% all the time but sometimes goes to 0 then back to 100, I guess this is a code thing... is there anything I Can provide to help improve?

[qwep]

CPU load 100% in GPU miner =(

yep
