seems GroestlCoin will be first coin for NVidia cards))

Groestl to the moon  

This could be big news for us and may speak to the flexible implementation of the Groestl algo on differnet platforms.

Grøstl has good performance on a wide range of different platforms, and counter-measures against side-channel attacks are well-understood from similar work on the AES.

to me, contact
Hi src, thanks for your email.
It is interesting for us to learn about this development, thanks for letting us know.

All the best with this project!
-The Grøstl team

srcxxx: Maybe you could suggest to the Grøstl Team they open a GRS wallet for donations to support the future development of the Grøstl algo.

This would make our coin's relationship to its algo unique!

PR IDEA

Anybody here who knows a good-looking Danish or Austrian (or German) girl willing to upload a cute, breezy vid clip to help us pronounce the word Groestl would be helping out immensely!

I may go to Austria myself in a couple weeks to try and get some footage of people pronouncing Groestl from the streets of Vienna. I am hoping it will be a playful introduction to this green algo. I will also source the finest Groestl in Vienna for eats

Anybody based in Austria or Germany can start doing this NOW

Anybody in Denmark / with Danish connections can do the same

Between the Russian forum, the French miner who posted test results, the Danish core dev and Austrian flavour we have an interesting european crypto twist. Possibly the Austrians will warm to Groestlcoin

Hi child_harold!

I like your idea. We need more PR material to explain people what GroestCoin is and why it is called this way.
Guys, any other ideas on this matter?

PS: I don't think it's a good idea to change the name of the coin. I think we just need to find a proper way of promoting the existing name.

Thanks
srcxxx

just call it G2

[srcxxx]

I congratulate you fellow Groestlers with addition of GroestlCoin on Poloniex!

I hope you will not be dumping the price like you did on NXT-E a few days ago :-)
Let's aim for at least 0.00000700 range for now.

Plz help me confirm Asus 6990 I only have 7,7Mh/s with I 21

[azhago]

Plz help me confirm Asus 6990 I only have 7,7Mh/s with I 21

Use -g 1 not -g 4 as mentioned on shp-sgminer page.

Use -g 1 not -g 4 as mentioned on shp-sgminer page.

Relly? You get better result with -g 1? 
On 6770 I use -g 10 -w 256, that gives me ~20% more speed compared with -g 4 -w 64 and ~30% more compared to -g 1 -w 64. I suggest you to try that too...

Hi ocminer!

I sent you a few personal messages asking to share your code for Stratum, but never got a reply. I even proposed a 0.1 BTC bounty. Did you not notice the messages or just don't want to share?
I understand Atrides@DwarfPool (I wrote to him twice also), he is getting 2%. But your pool is 0% and you also have lots of other pools (Max, Hiro, etc: https://max.suprnova.cc/)...

Anyways, I saw your earlier message in this thread regarding address_to_pubkeyhash() not working in hash python.
I've found the proper solution (i.e. I didn't just turn off the check). The problem was that hash python works on 80 byte input, but input length is just 21 for base58 decoded address (1 byte version + 20 byte public key) and so Groestl hash calculation was running out of bounds. That's in the spirit of sharing :-)

I'm going to figure this out eventually, I'm pretty sure in this [especially once I have the upcoming Saturday/Sunday free from work]. I even learned a bit of Python along the way (at least enough to insert Debug-prints into stratum-mining). Next thing is figuring out the Diff1, which is probably around 0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff00000000 (plus-minus 'f'). And after it, checking if shares are accepted and finally - tweaking MHS calculation for MPOS (currently it's showing like 0.05MH/s for my R9 290). Then I'll launch it.

My pool is going to be 0.8% proportional, everything is setup, I just need to figure the stuff above.
I'm going to be blunt about it, I'll use this 0.8% for promoting GroestlCoin, paying for hosting and I hope there will be some remaining for myself (to pay for time that I'm spending here).
And obviously, I'd prefer to work on GroestlCoin press article, website, or just pure promotion (like various emails and tickets to cryptsy, poloniex, altoutlet.com, etc) than browsing through google, bitcointalk and "vi" editor in Unix to figure out what's wrong.

PS: I wrote do you directly because you are pretty active in this thread (mostly promoting your pool :-) ), while I haven't see other pool operator posts here.

Thanks

If you're looking for a reliable, fair Pool:

https://grs.suprnova.cc

Still lots of free slots for miners, hop in, we're finding blocks on a regular basis and got all the Googles.

Our Daemon is patched against the various fake share attacks, You really get What You mine.


Still 0 % Fee !

This pool paid earned coin less than cpu-pool.net.That's true

Yes it has wayyyy less hashpower than cpu-pool.net, it cannot pay more than Just compare the overall statistics and you'll see there mostly the same, just one has high hashpower, the other one low.

I agree with kingimg. I had some worker there. But historical, 4 week,average percentage from suprnova = 154.78% Historical average cpu-pool.net = 104.69%

If you looked at last week is little bit good, but i mean something is wrong. This pool so long dont have luck  or what?

Pls update first link for this pool cpu-pool.net , till today I do not hear about it.

Those overall stats are probably wrong since the code (mpos) is not well implemented for Groestl's Target_Bits, best is always to mine 24h on this pool and 24h on the other pool, than you see differences. If I change the target-bits to for example "20", I get overall percentage of 75%

Hey src !

Oh sorry I currently have 28 messages in my inbox and no time to read :-)

If you urgently need me, always drop me a mail @ admin at suprnova.cc and I'll respond quick.

I'll write you a PM later, GRS is different in many things, there will be some tweaking neccessary, not only in stratum
code, also in mpos (the average stats are a good example for that...).

However, i'm using/testing the code with node.js instead of the old, buggy stratum python code since its much easier
to debug (and fix ). have a look at https://github.com/zone117x/node-stratum-pool - i use this but my codebase is really
not ready for the public atm - it's a ugly debug build - it is running fine and without problems but its in no way cleaned up

[azhago]

Plz help me confirm Asus 6990 I only have 7,7Mh/s with I 21

Use -g 1 not -g 4 as mentioned on shp-sgminer page.

Relly? You get better result with -g 1? 
On 6770 I use -g 10 -w 256, that gives me ~20% more speed compared with -g 4 -w 64 and ~30% more compared to -g 1 -w 64. I suggest you to try that too...

Maybe it's related to HD6xxx architecture.

On HD7950 and R9 280x -g 1 give me the best perfs.
R9 280x @ 1200MHz, -I 20 :

-g 1 : 7.6MHs
-g 2 : 5.5Mhs
-g 10 : 6.2Mhs

Same thing on HD7950 : best perfs with -g 1
But, HD7850 have a little more perfs with -g 10 instead of other settings : (10%)

Ok, thank you for this. Please send your value for diff1, if you can. It is from stratum-mining\lib\template_registry.py.

I'll provide you the NXT-E GRS/BTC ticket price in MPOS in return:

Code:

$config['price']['enabled'] = true;
$config['price']['url'] = 'https://nxt-e.com';
$config['price']['target'] = '/api/stats/?coin=GRS&exchange=BTC';
$config['price']['currency'] = 'BTC';

  private function getApiType($url) {
    if (preg_match('/coinchoose.com/', $url)) {
      return 'coinchose';
    } else if (preg_match('/btc-e.com/', $url)) {
      return 'btce';
    } else if (preg_match('/cryptsy.com/', $url)) {
      return 'cryptsy';
    } else if (preg_match('/cryptorush.in/', $url)) {
      return 'cryptorush';
[b]    } else if (preg_match('/nxt-e.com/', $url)) {
      return 'nxte';
[/b]    }
    $this->setErrorMessage("API URL unknown");
    return false;
  }

getPrice() function
...
      	case 'nxte':
      	  return @$aData['CurrentPrice'];
      	  break;

Yes, I saw the NPM here: https://www.npmjs.org/package/stratum-pool. However I wanted to set up MPOS, I kind of like it.

PS: I also sent you an email.

Thanks

You can use the stratum from nomp as a plug in for mpos too (that is what i am doing)
