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

[DubFX]

all cpu coins died,
big cpu farmers are mining GRS now,
they dont even pay for electricity,they dump and dump.that is why there is so high hashrate but the price is still going down!
we should do something against it.

Uhm, you have any idea what could we do?

Is any problem with Dwarfpool? I keep getting disconnected....

Uh yeah i was thinking about switching to groestl but this kinda keeps me off
A bunch of CPU farms dumping isnt all that attractive right now

CPU/GPU farms… bah Humbug!

The DGW Difficulty adjustment should minimize their profits and discourage farmers.



In the meantime its a good time to pick up more GRS while price is still low

Dwarfpool works fine, please send me your login-wallet and IP address, may be it was blocked in firewall.

Groestlcoin has been added to the The CPU Coin List. Here is the direct link to the Groestlcoin page.

Let me know about any errors or omissions and I will correct ASAP.

thanks btc-mike

GPU advantage among CPU is lower than on different algo, but i don't think there is so much cpu farm. Big miners switched to alternate algos instead of scrypt, and some come to GroestlCoin, that's all. It's still possible to mine for little miners, and a good time to buy. I almost double my GRS amount buy trading (with some profit too)

3rd place taken, new BOUNTY for 4th!
Link to competition: https://bitcointalk.org/index.php?topic=560587.0

This one comes from one of a Russian member of the community. It's got a fish, drum and bass and Groestlcoin and its pretty fucking funny - what else do you want??

Retweet, link etc etc if u likey

Just opened new pool (proportional, 1% fee) - for 100 first miners fee will be 0%

https://www2.coinmine.pl/grs/
Primary Node: mine1.coinmine.pl:3000

Currently looking for few miners to proof its working properly (and finding blocks).

I'm mining on it right now. Reported hashrate is too high and vardiff doesn't seem to kick in.

[mikk2k2]

Think we'd be able to put together a multipool for GRS?

thanks feeleep - mining there now

Could a few of you please move your hashrate over to coinmine please?

help feeleep with his testing and spread the hashrate.

We now have 4 good pools

While you're here could you speak to the Groestl (Grøstl) algo's performance on NVIDIA compared with other algos
thanks,

Dorian (child_harold)

Groestl is quite slow because most implementations use a lot of random lookups in so-called T-Tables. Regardless whether you manage to get cached read access to these T-tables, or whether you put them into shared mem - the hardware still has issues with the random access from many threads. The same problem is seen on AMD devices, I suppose.

There are ways to work around these performance issues, and we have implemented one. I won't be more specific. Our different approach uses more power, but it is also up to 3 times as fast.

Thanks for the reply Christian:

3 questions please

1. Are the hardware issues experienced with the random access from many threads something like "parallelisztion resistance"? Or in other words would that make this algo offer low(er) ASIC advantage compared to other algos in use? Would producing ASIC hardware therefor be more difficult and result in a lower / reduced ASIC advantage compared with SHA-256?

2. So NVIDIA will run 3x current speed with your "different approach"!?

3. Can you imagine an efficient ARM miner for this algo (a BOUNTY has been offered)

Any other info bout what makes this algo different (quirks, surprises etc) from others used in crypto mining  would be enlightening

thank you Christian for your generous contribution to this conversation

r9 290 GPU , According to information on the page 9.8 MH/s ..
I have sapphire R9 290 GPU .. But 7.8 Mh/s

Please Can you give r9 290 BAT file settings

My Bat File

sgminer.exe -k groestlcoin -o stratum+tcp://erebor.dwarfpool.com:3345 -u FgYka3E3S9jXU7Q3iZtxtT43j4RdnnyrQP -p x -d 0,1,2 -I 18

for starters try upping the intensity to 20 or even 21

Attention DwarfPool MIiners

Please begin re-distributing your hashrate IMMEDIATELY
DwarfPool has way too much hashrate atm

So can some of you please move your mining to (in this order of priority):

https://www2.coinmine.pl/grs/
https://grs.suprnova.cc/
https://cpu-pool.net/grs/

all are good pools run by experienced Ops

It is important for GRS to have an evenly distributed hashrate

cheers

[srcxxx]

Please join the new pool at http://grs.cryptohunger.com/

Vardiff 1-1024 (good for CPU)

Multi core server

DDOS protected

0.8% proportional fee

Pool fees go towards GroestlCoin promotion

1) the implementer of the SPH library chose a table based approach because it works fast on CPUs. This doesn't work as fast on GPUs though. On GPUs explicit computations are usually faster than table lookups. It's just this particular approach taken that is somewhat resistant to parallelization.

2) yes.

3) maybe on 64 bit ARM platforms with 4 and more cores, using wide 128 bit SIMD operations (NEON?). I am not very familiar with ARM, so I can only speculate. In fact, our alternative approach would also apply here (and to Intel SSE2/AVX2)

4) it's very similar to AES, but somewhat upsized.  The algorithm uses interesting maths based on Galois Fields GF(2^8).

[cryptonit]

so if i understand cbuchner right its only a matter of time better performing miners on all platforms will be avaiable

will that reduce power savings compared to scrypt to zero or even optmized mining software will use less power?

we at diamond will for our coin feature relaunch choose a non scrypt algo

and groestl could be the new one

we want to avoid injection vulnerabilities of multialgos like x11 and twe
but we also want powersaving for our miner
