are you not afraid to burn tablets etc which are fanless ?

A good implementation should handle this

Also this is about the ARM servers and PC's of the future

Ok that's really nice  u should also consider to make GRS a POS 3% or something, best algo + pos hype = win = next sheet 

It has been discussed. As somebody mentioned earlier the PoS thing certainly is "fashionable" atm. I dont give a  flying f*ck about fashion. Switching to PoS could mean losing our individuality imo

Oh - and did I mention…?

Im loving the cyphermonk feeling I get from mining pure PoW Groestl.

this should be in bold.

I don't give a  flying f*ck about fashion.

there, I fixed it

And also this algo doesn't produce mutch heat, does it?

[alinutu78]

Why so low price? 

[child_harold]

Why so low price?  

because GRS is grossly undervalued atm.

We have this unique algo that can be AES accelerated = reduced efficiency gaps between platforms = good performance on wide range of platforms = ultimate PoW.

What we are "selling" is more subtle than most coins and the market will take longer to appreciate its awesomeness and significance for all of crypto mining

alinutu78, need I show the „dumpers” meme again?
părerea mea e să stai pe-aproape și să minezi cât e încă ușor de făcut rost

I wont stop mining...just wondering about dumpers
multumesc frumos

ARM's 2014 processors will blow today's smartphone chips away, with 3x the performance or 1/4 the battery drain

… just sayin'


NEW! A new Grøstl-256 NEON implementation using bitslicing (48.6 cycles/byte on Cortex-A8, Hercules eCAFE) is available in eBASH.

^^ sounds promising

Why so low price? 

At this time, marketing is more important than the technical maturity

Miners not interested the possibility of mining on ARM / CPU, less power consumption, but what is the current profit.

Good performance on many platforms

To quote from the conclusion:

In this work we have proposed two optimized algorithms for MixBytes, the MDS mixing layer ofGrøstl, which allow to speed up Grøstlon on various platforms. Furthermore, byte slicing provides the possibility to parallelize the Grøstl computation if the registers are large enough and parallel AES S-box table lookups are available. This is the case for Intel processors including the new AES instructions set or in general, using the vpaes implementation. Both implementations show that Grøstl can be implemented efficiently on very different platforms.

I tried the apk on my galaxy nexus gsm:

Groestlhash: 10.4264 KH/s

So these initial benchmarks are getting ~10KH/thread
So would a 2 core ARM chip support 4 threads i.e. 40KH/s ?
Now I m sure we're gonna end up with much more than 10KH/s per thread.

Even at this early stage the power efficiencies are interesting. Im gonna make a big assumption but if 4 cores > 8 threads @10KH/thread = 80kH

R9290        150w      ~9000 KH/s
Cortex A9   1.9W          ~80 KH/s  --->> so theoretically 190w required to push 8000kH/s

So even at this early stage (permitting my assumptions about multi-thread performance are true) the Cortex is only ~30% less power efficient (hashrate/watts) then an R9290

Optimizations leading to 15kH/s or 20KH/s per thread or more should mean the Cortex A9 is more power efficient than the AMD GPU.

These new Cortex-A17 procs (2014) seems considerably more powerrful than the A9

Democratizing Mining

Yes.  But just remember - this is only going to help narrow the gap somewhat compared to SHA256.

A really good GPU implementation is still likely to be, say, 8-16x better than a CPU implementation in hashes/second/$.  An ASIC implementation will have a very big gap.

(None of the GPU implementations are any good yet compared to what they should be, at least, until C&C release theirs.)

So don't make too many strong claims about how democratized it will be.   It's better than Bitcoin's algorithm.  Whether or not it's better than, say, Momentum, is an interesting question.

[MinerSVK]

WOW, MINTPAL, what a stupid choice, you will get nothing more than dumpers! GRS will be dead like HIRO.

Remember this day, It is the day when died Tito Vilanova and GRS follows him..

Hence democratizing… not democratized

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!
