I’ve got the original Myriad-Groestl srcxxx github optimized files if anyone is interesting in forking them - basically changing the name (since they’re open source to begin with) and then posting it to github. Send me a PM if you’re interested.


Hi HR, thank you for keeping us up to date with your stats. I will have a look on the original Myriad-Groestl srcxxx optimized bins. I thougt these bins only work on his pool. Maybe i can change this to get it work on every pool. Since difficulty is dropping again i could be profitable again to put a bit more power to my cards.

He originally developed two different optimized kernels that significantly increased hashrates over the previous sph-sgminer ( https://github.com/prettyhatemachine/sph-sgminer ). His miner, grs-sgminer, allowed you to use the "-k groestlcoin" switch on any pool, or the "-k optimized" switch that only worked on his pool.

My understanding is that he depreciated the github files for his original grs-sgminer that allowed you to use either switch. I could be mistaken though, but the idea that I have is that his current grs-sgminer only works with his proprietary "-k optimized" switch. If that's the case, then I think it would be interesting to fork his original grs-sgminer making available new installs once again that permit the use of any of the non-optimized kernels on any pool of the miner's choosing (grs-sgminer, using the "-k myriadcoin-groestl" switch, more than doubles the hashrate of sph-sgminer with only about a 20% increase in electrical usage - not bad at all).

I would like to correct something in the above post (it's been a while since things have been on "autopilot" and my memory didn't serve me too well, and, today, when I was putting together some stuff for DigiByte, I realized my mistake):

It was grs-sgminer's original "-k groestlcoin" kernel that doubled sph-sgminer's hashrate, not the "-k myriadcoin-groestl".

The "-k myriadcoin-groestl" kernel quadruples the original sph-sgminer's hashrate! (I even understated it to you DigiByte in the PM I sent by saying it tripled the hash rate . . . it's actually a quadruple!)

More specifically, with a 7950, sph-sgminer ran at about 5 Mh/s, grs-sgminer with -k groestlcoin at about 10 Mh/s, and grs-sgminer with -k myriadcoin-groestl has a hashrate of 20 Mh/s.



If you wouldn't mind sending me the source code I'll take a crack at it.

It's out of my hands now as it's been sent to DigiByte to use as they see fit. Perhaps you might send them a PM offering your services.  Smiley

I think it should be relatively easy to clean up (a few AV products generate alerts for the Windows exe, for example) and turn into something DigiByte official (giving credit to previous developers of course).

It's by far and away the most profitable way to mine DGB.
