[ANN][GRS] Groestlcoin | 1st to activate Segwit & Taproot

was groestl made by satoshi nakamoto?

I love how the team allude to the "mysterious gruve_p", trying to create (? ) some similarities with satoshi

I just checked gruve_p's very first post on the forum, before he lauched GRS, and got a good laugh out of them:

Hi all!!

mining bitcoin with cpu it is nonsense ))

I never gamble

A day after the "I never gamle" qoute, our satoshi lauched GRS hehe. When I figure out how to put text in my signature it will be "I never gamle" (though I do it most of the time)

Hello guys, I tried to crank-up GRS mining today to see what speed I can get. I will share my results and configs. If somebody is able to squeeze higher speeds with the same gpus, please share your configs.

does anybody have a working batch file i can see???

Im using a r9 270 and cant seem to get a batch file that doesnt auto close when i try to run it

i have 2 x R9 290 on win7x64, i am using the dwafpool miner

Code:

set GPU_MAX_ALLOC_PERCENT=100
set GPU_USE_SYNC_OBJECTS=1
C:\crypto\miners\gpu-DwarfPool-grs\sgminer.exe -I 19,19 -g 1 -w 256 -k groestlcoin --no-submit-stale -o stratum+tcp://erebor.dwarfpool.com:3345 -u FhVtNTU5Qm3267ApPmfcyS1iRcN9tdYNE7 -p x --failover-only -o "stratum +tcp://moria.dwarfpool.com:3345" -u FhVtNTU5Qm3267ApPmfcyS1iRcN9tdYNE7.elite02 -p x -d 0,1

Working!!

Thanks!

Thank you for the settings.  I have a MSI 280x 2G OC as well and that setting bumped me from 6.3mh to 7.3mh

How do you know which difficulty to use for the NOMP pool?

I know you can choose the vardiff port, but what should determine which you should be in on your own, and when to move?

Thanks for any insight.

The choice is connected to your hashrate iirc. Lower hashrate > Lower difficulty choice.

Somebody else can hopefully weigh in with more detail

Thanks Harold. I get the basic idea, but just have no idea where you would draw the line or if there is some basic formula or something to watch for that would give you an idea you should move up or down in difficulty.

I have about 19.4 Mhash/s but wonder sometimes about how sometimes you get 6-8 accepted work blocks (yay!!) in one stratum block, but on others you get none.

Also wondering if there is a way to see what the VarDiff is actually working at when you choose that one.

I can't be the only one who wonders these things

Well with that ~20Mhash u dont need those lower diff settings. I think they'd only benefit <10Mhash

id just run port 3333

it would be nice to get a little bit more info about how many blocks are found by the pool each time it is found, and what is the speed and the balance of each user.

I would recommend to always use vardiff (port 3333). Unless you specifically want higher difficulty.
VARDIFF will automatically try to find your optimal difficulty so that you send approximately one share in 15 seconds.

Thanks

I assume you are using ccminer or CPU miner. Because in sgminer this information is clearly visible.

In the long run, the difficulty doesn't really matter. And you get same payout anyways. For example, some of the Scrypt multipools use a really high share difficulty (512 or 1024) to reduce server load.

19.4 mhash is probably difficulty of 32 on Groestl. I also have 2x R9 290, which gives about 19+ mhash, I can double check what I'm getting if you want. But as I said, if you are not sure - just use VARDIFF.

I completely agree. And I think this functionality is being worked on by the NOMP team. But to be honest, I don't think it is coming in the next weeks/months.

Here is what you can do at present time:

1) Found blocks are displayed in "blocks pending by pool" section in http://groestlcoin.biz/stats
2) You can see the public payouts ledger by the pool here: http://grs.42tx.com/address/FfHLhRfu5Gk4q8WxGu5Zngd3KxJCeNfthh
Notice how all that got mined is sent to miners by clicking on individual transactions.
3) And finally, you can "sort of" see your hashrate here: http://groestlcoin.biz/api/stats
I believe that it is possible to digest that info and show it in a nice way. But I'm not going to spend time on this yet. If you need statistics, one of the MPOS pools is a better choice.

PS: In case you are wondering why this NOMP pool is 0% fee... I'll tell you. That's because of another problem in NOMP. I actually set it to 1% fee, but it ignores it. So enjoy the 0% for now (until they fix it).

Hey guy,are you serious.GPU at 1200,Can really go that high?
I tried my asus dc2t and his iceqx2 280x can not run beyond 1120.
What is --difficulty-multiplier for?

Yes, GPUs can go as high as 1200 or even higher (I have R9 270X that runs stable at 1220), but only on certain algorithms. Groestl is a very good example of this. For reference, same cards can only go as high as 1066 on Scrypt.

Difficulty multiplied is required by sph-sgminer application only. In case of ccminer or CPU miners, it is not required. I actually think it is a pretty stupid idea to make it a separate param, or at least not defaulting to a proper value.

nice, a gpu-coin!

What is --difficulty-multiplier for?

I have logged a change of default value request for this difficulty-multiplier in sph-sgminer thread. Hopefully, next version of sph-sgminer will not have it at all (i.e. it'll set it to proper value automatically)

can't get it to sync, nodes?
