I am sure we can do better Wink

The cuda guys are saying that optimizing groestl will mean much faster X11 and quark.
I don't think so: I did some tests on X11 and groestl takes about 20% of the time; so even if you double its performance, globally you will just get 10% improvement.
Granted, 20% is much more than what is taken for example by keccak (just a couple percent).

maybe he got something else in addition to groestl. He was saying cuda gonna own groestl, x11 and quark. He seems serious and do not want to release the source code.

Groestl is useless atm, cause Cuda Miner is 2-3x faster 

no :
780ti : 11Mh/s (don't know if oc or not)
R9 290 : 9Mh/s (gpu@1100)

R9 290 9.9 Mh/s (gpu @1100)

amd sph miner beaten but not so much

how about power consumption ? If put that into consideration , which is better ?

750ti at 8 Mh/s under 75 watts per card

More like 45w most of the time :p

how do I raise the diff so i can mine quark on a pool with gpu?

--difficulty-multiplier 256

[pengoau]

Can I use this for scrypt-n & x11?

Update well specifying nfactor with zuikkis or darkcoin kernel fails to load sph-sgminer.

Atm I'm using sgminer for scrypt-n and sph-sgminer for x11. Would be good to use just the one program.

ATTENTION DEVELOPERS -----  I WANT YOU TO KNOW

I really appreciate you taking the time to add the support for simple inflation coin

I sent you all the coins (sic) I mined over almost a month as a donation as a show of thanks .....

The russian thread (via google translate) is pretty active for the coin

They got quite a kick out of the fact that the gpu showed up. 

They are also planing to launch a new coin based on proof of stake ( or so they say)  and let users of this coin keep their coins by importing their
keys into the new client !!1

Anyway , was a job well done and thanks again.  Will try to make another donation in near future for your efforts.

Can you give a link to that russian forum thread?

[phm]

did anyone find a solution to 10% hashrate drop after 10mins of mining darkcoin with r9 290s?

If I remember correctly the drop was caused by screensaver activating itself.

as req russian thread for simple inflation coin

if you have time it is quite an 'entertaining read' !!

Can you give a link to that russian forum thread?

Interested to know if sph-sgminer can mine blue midnight wish on gpu right now?

I think x11 includes blue midnight wish. But can sph-sgminer mine it if it was a standalone algo like groestl coin?

Currently it can't.

anyone with a great X11 config for R9 290 ?

anyone with a great X11 config for R9 290 ?

Go on the darkcoin thread, there are plenty of miners who can help. There are a couple of threads on r9 290s including the Tri-x.

Are you sure about this? Because for example hash of BTC block 10 (difficulty = 1) is:

000000002c05cc2e78923c34df87fd108b22221ac6076c18f3ade378a4d915e9

and hash of QRK block 600 (difficulty = 1.01576304) is:

00000096b99f154706b957c0e36cc4bf3789849e8a0684278dffac607b404641

so QRK definitely has higher target than BTC for this difficulty, otherwise this block would not be accepted. I'm not an expert in this, though.

Also take a look at:

https://github.com/bitcoin/bitcoin/blob/master/src/rpcblockchain.cpp#L36

and

https://github.com/MaxGuevara/quark/blob/master/src/rpcblockchain.cpp#L31

In BTC dDiff is multiplied/divided by 256 until nShift is 29 while in QRK it's multiplied/divided by 256 until nShift is 30 - so IMHO for two difficulties with the same value target value will be shifted by 8 bits.

Note that sph-sgminer displays network difficulty correctly for Quark and QubitCoin. It wouldn't be correct with wrong multiplier.

I compiled sph-sgminer version 4.1.0-101-g7678 on my Xubuntu system with 3 X 7850.  sph-sgminer works good but my last GPU does not work when I use export Display=:0 in my shell script to start the miner.  The GPU with the issue displays temp & RPM but hasrate remains at 0.000, and eventually the miner gets hung after a few minutes.   The only way I can get all three card mining is to comment out export Display=:0.  Should I try a prior version or is there something else I should try?

Hi guys,

I just added X11 (darkcoin kernel only for now) algo to whatmine.com !!!

[yang5034]

such a good miner thank you

as we can read there groestl implementation of sph perfirms like 3x slower thant the nvidia mining implementation of cbuchner

will we see improvement of sph regading groestl soon?
