Hi Cryptonit!

NOMP pool software supports coins switching right out of the box (see my NOMP post on previous page). You just need to provide a script to detect which coin is more profitable and figure out what to do with login address.

I was planning to implement this feature on my cryptohunger pool after you launch.

Thanks

I'm currently testing a new GRS pool using NOMP (https://github.com/zone117x/node-open-mining-portal).

The pool doesn't require registration, just point your miners to and specify your GRS wallet as user name, password is ignored.
1.8% prop, payouts every minute, minimum payout 10 GRS.
Note: fee is rather high, because NOMP pays for orhpaned blocks and there is no extra auto/manual transaction fee.

UI frontend here (not much info currently, you can't even see your personal hashrate)

Currently in BETA status, use at your own risk. I'm running it overnight with my rigs and will let you know tomorrow if it is safe to use.
If you feel adventurous - join me. And if you find problems - let me know and switch to other pool (like the currently running grs.cryptohunger.com).
As per NOMP documentation, everything should work right out of the box, but you never know.

PS: I'm planning to use this pool setup for future Android/Web mining endeavours, as it doesn't require any registration. So you'd be able to mine straight out of your wallet.

Good. Did you have to use the --difficulty-multiplier flag?

Yeah. Thanks.

Also, this logo is "iOS 7 compliant" :-)

It's simple. If your sgminer says unrecognized option, the it is not the latest version.

You can get compiled versions from here: https://bitcointalk.org/index.php?topic=475795.0

It has some command lines too

Thoughts?

Что это означает :-)
?

Try adding this parameter to your command line: --difficulty-multiplier 0.0039062500

If the problem still persists - please switch to my pool (grs.cryptohunger.com) and I'll try to see if I can help by looking at my logs.

Hi!

Please provide a screenshot.

Also, to all people using ccMiner... If ccMiner shows you huge hashrate, it probably means that shader did not compile and you are not mining anything.

Thanks

Thank you for this. I inserted your results into the spreadsheet.

Your device is quad core, so in theory you could be getting about 140KHs (that't about 10 GRS per day).

There is also the possibility of doing hashing in RenderScript, which will involve GPU on the device. Your GPU is 12-core, so should be a nice speed boost. I might look into RenderScript later.

update on Andoid mining test...

Version 3 now has 3 different hashing algorithms. Please re-download the APK and retest.
Note: if you don't know what an .APK is, don't do this.
Note: this is not a miner, just a speed test. And it is single-threaded.

You should get something like this:


Please upload your results here: https://docs.google.com/spreadsheets/d/1hTOUdJZrKqrNDXTIbXgNvJtj_fnpECREcs-eHxaGrZc/edit?usp=sharing

What about overclock? My Radeons run at 1200Mhz core on Groestl and only 1066 on Scrypt.

Also, looks like you're only getting 7.2MH/s. Please try the 18 April build of ccMiner. You should get 9MHs. See here: http://cryptomining-blog.com/2097-updated-ccminer-0-5-with-improved-performance-for-groestlcoin-grs/

Thanks

Thank you for this!

yamminer does work, but looks like you need to try all builds to find the one that works best. There are like 8 builds of it.

Also, on older PCs the original CPU minerd works faster.

Please use the new link: https://docs.google.com/spreadsheets/d/1hTOUdJZrKqrNDXTIbXgNvJtj_fnpECREcs-eHxaGrZc/edit?usp=sharing

We need NVidia GPU and CPU results.
Please share your settings.

If you have AMD GPU - please also share your settings, but this is lower priority. We've got lots of AMD results, but not enough CPU and NVidia.

Thank you!

OK, now NEON should work. Please try this.

On emulator I'm getting this:



!!!Note: this is NOT a miner!!! It's just a speed test. Also, it is single-threaded.

Thank you for your tests. Looks like we need NEON optimizations to get a good hashrate. Also I'm not sure if I compiled Release or Debug.

I think I added NEON, but now it just crashes emulator. I'll continue research. If you can help, the code is still in https://github.com/srcxxx/grhashAndroid (for those devs, who want to contribute)

Thanks!

Can somebody try this APK on their fast Android devices and let me know the speed and device name? Note: if you don't know what an .APK is, don't try it.

This is ARM compile of SPH library performing GroestlCoin hashing.
I'm also working on NEON (ARVv7E) version, but getting weird GCC errors, I'll keep you posted.
The source code is here: https://github.com/srcxxx/grhashAndroid

!!!Note: this is NOT a miner!!! It's just a speed test.

PS: This is what I'm getting in ARM emulator :-)

I've found a nice Android wallet implementation of a wallet and we can fork from it to make GRS wallet.
See this link: https://play.google.com/store/apps/details?id=hashengineering.quarkcoin.wallet

This is the link on how to do this: http://www.hashengineeringsolutions.com/create-an-android-wallet/

I've got a few questions to the community:

1) Do you think having a wallet for Android is important for GRS?

2) Does anybody want to implement it and get a bounty?

Thanks
