price decrease every day,exchange amount is very low,and it is still hard to dig

well time to buy back in when you sold it. Might go back to 1.5k again. But the question is do you believe in this coin ?

Doesnt look too bad, I believe you were at 25ish if you hadnt sold your 120k grs

nice ,i find my address in the top 100 list,
i believe GRS is a good coin,hold it like a rich man Grin

Had no idea this list existed Cheesy

Good to see there is'nt one account with a bigillion in it!

New M7q version of yam miner is available. Major addition is support GroestlCoin (GRS) mining.
GroestlCoin mining with yam M7q brings major performance improvement on modern Haswell CPUs on Win64, Linux64 and MacOS X.
More docs in readme.txt included in distribution.

yam M7q available for downloads at regular locations:

http://sdrv.ms/18wfjYX
http://pan.baidu.com/s/1xOOWa
https://www.dropbox.com/sh/jvp4wwek8jpohj7/RlW6hzYqTz

Test with dual-Xeon 2687W 32 threads :
old cpu miner 64bit : ~4460KHs

Yam M7Q : I let some time to reach max perf (auto-tuning) : 5800~5820KH/s

Big improvement, nice job !

Thanks.

I guess maintainers of groestlcoin.org shall update miner performance charts basing on those stats

OK, first results...

NOTICE
This code is completely unoptimized and is single-thread. Also, it is not a miner. It just does 10 times of 1024 hashes using GroestlCoin algorithm and prints the time it took.

Win64: 160KH/s
Win32: 60KH/s (so yes, having Win32 version with same speed as Win64 will require some tweaking)
Chrome: 1.5KH/s
FireFox: 12KH/s (that's because FireFox supports asm.js, I believe)

For those, who want to try it out for yourself, here's the link: groestlcoin.org/grshash.htm

Again, this is not optimized in any way! This is just proof of concept. To show that it is possible.

Next, I'm planning to compile for iPad and Android and see the speed results.

After that, we will move on to speed optimizations.

For developers:

Please see https://github.com/srcxxx/grshash. It has dead-simple code.
Perhaps you can use it as a basis when tweaking CPU miners.
For example, I noticed that our CPU miner is not using SPH library. And so it's single thread speed on my PC is 240KH/s in Win64 (vs 160KH/s with SPH in my little grshash project).
So there is quite a bit to explore here.

I'll keep you posted.

Thanks

Any feedback?

I like our logo, I dont want new logo.
I adding 2500 GRS for 50% or more performance boost to AMD miner or 5000 GRS if there will be 100% or more performance boost. If there will be 100% or more performance boost and only max. 50% more power consumption, I add 5000 more GRS. Best solution for us will be improve spg-sgminer groestl core. (but this must be open source, for claim.)

thanks for adding to the Bounty. nice one jox!

Dont have much time now - will flesh it out later…
srcxxx (amongst others) has recently mentioned PoS and maybe switching after a few months. So…

Idea

1.keep mining PoW for couple more months / summer end
2. then move to PoW/PoS combo
3. Move to combo would coincide with a possible rebranding / new logo / PR blitz

Bounties.

This has to be sorted out. I dont officially represent the coin but those of you who know me know Im passionate and dedicated to it.

so in addition to any official bounties I pledge the following

5k for a new logo (to be deemed by consensus better than the existing one)*
10k for 33% or more performance boost to CPU miner (64 or 32 bit)
20k for 50% or more performance boost to AMD miner
25k for ARM miner (code to be made available. payment after verification)

* I like the idea of using the Ø symbol in it.

Others are welcome to pledge themselves (I will track the pledges) and if this is acceptable people's words will count till such time as the Bounties are formalized. Anyway my word is good and I've have paid all Bounties I have offered in the past. Ask instacash for example.

Blue skies and helicopter thinking…

the ARM miner you can consider my personal project but i believe in it. Without getting into a long spiel I would simply point out that Googlecoin would run on ARM. ARM procs are getting a lot faster a lot quicker.
http://mashable.com/2013/12/13/google-intel-arm/

If this coin went PoW/PoS I love the idea of ARM chips helping to secure the network in years to come. In no time the public will only carry ARM. The landscape of mining will be very different in no time at all. The ARM implementations exist and it should be doable
https://bitcointalksearch.org/topic/m.6238355

The similarity to AES might also mean Grøstl gets hw accelaerations.

Any feedback?

Hi all!

Just wanted to give you an update on what's coming up shortly...

* Paper wallet for GRS (based on bitaddress.org)

* Some experiments to find the theoretical maximum mining speed across different devices: Win64, Win32 (is it possible to make it as fast as Win64 or not?), ARM (to be tested on Google Nexus 10), iPad (iPad3 & iPad Air tests) and... HTML JavaScript (Emscripten cross-compiled output).

Please note, that it is not going to be a miner. Yet.
It'll be just a simple application that will generate lots of GroestlCoin hashes per second and print out the speed.
Once completed, I'll upload all sources to GitHub for public access.
(Hashing code will be based on SPH library)

Thanks

Primary Node: mine1.coinmine.pl:3000

feeleep

Guys who joined us from the beginning earned 20% more than expected (lucky pool) and we still have 50 GRS bonus for block finder - spread the hashpower and join us!

Could we move a bit of hashrate over here pls?

It's just me and 2 otehr guys Shocked

C'mon!

i'll be back tomorrow. Cheesy

I'm an opensource programmer and I program and mine for fun. I get money for programming on my job.
But I also think that everybody is free to ask whatever they want for their work.
There are "professional and highly skilled developers" who program for free (like myself) and bad programmers who ask for money :-D

I don't think we intend to ask for mining fees or anything like that. But we would like to see nVidia users have a bit of an advantage in the mid term at least. Because if everybody mines faster, there is no benefit for anybody. Wink

Hence we would like to take the time to make nVidia specific optimizations (e.g. I intend to make heavy use of the warp shuffle feature for Groestl which does not currently exist in OpenCL). And when needed we may also decide to do a binary only release - requiring us to find workarounds to stay in compliance with GPL terms.

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

it took us longer than a week and lots of debugging to come up with the new implementation. It took some serious brain skillz too. Wink

And no, we don't intend to open source this.

I'm still trying to wrap my head around the idea that mining with a proprietary GPU miner closed to other devs is a good thing. I can't really seem to do it.
…

I missed the part where you had a constructive suggestion for how to pay for weeks of work by two professional and highly skilled developers.

…

Not entirely sure how to respond to this except by saying Im offering a 20k bounty for AMD and thats 0.2BTC on a better day. Id hope anybody developing for GRS would see then potential growth here and enjoy the celebrity such optimizatiosn would make. Also I hope others will add to my existing bounty or create incentives of their own.

It seems to me the argument you make could apply to almost all bounties for all optimizations of new coins.

Obviously I hope devs feel properly remunerated for their time, even if not today then in a month Wink

thanks
