Aaand it's out: https://github.com/tsiv/ccminerShould be an easy modification, right now my X13 is using the same code for the first 11 algos as the original X11. At the simplest it just takes a recompile after throwing in the new groestl version. I did end up messing with the original echo hash, it seemed to have an extraneous xor that made the full 512 bit hash come out wrong. Then using that result for the additional hamsi+fugue hashes kinda ends badly. The funny thing is that it worked fine for X11 because it was the last hashing algo in the chain and the X11 algo only takes the first 256 bits of the hash, discarding the rest and the flipped bit ended up in the discarded part. Was a bitch to track down for sure. Hi, let me take the time to congratulate you for this excellent piece of work. The fact that you were able to debug the Echo hash proves that you are developing absolutely at the same level as the C&C Hash factory at its best. Which is now unfortunately the "Cash factory" because Chris H (C. H.) just recently dropped out so he could focus more on his business. I salute you, noble contributor!!! Now back to making a killing with XMR and BBR , sorry

Seems like you've already got rid of the MAXWELL_OR_FERMI constant, superb yes, the table based Groestl is history, and so are the architecture dependent optimizations we made for it. Bitslice, baby! That's what it's doing now. More use of ALUs, much less use of the memory controller. Getting this to run was about 2 weeks of research and implementation. And then some more making the Compute 3.0 optimized Quad version you're enjoying now.

Hello, I was trying of Groestlcoin with ccminer50.exe on my 750ti, I looked at the configs for 750ti on cudminer.cc ambiohazardccminer - v1.02groestlccminer50.exe -q -s 1 -a groestlStock | Stock | Stock8800kh but I am getting no where near that hashrate , is this correct or am I doing something wrong.

so I guess now jpc algo is using a lot more groestl Previously Groestl was also eliminated in the 1st and 2nd rounds, leaving only 1/4th of the hashes to be evaluated. Now with the faster Groestl I made it run Groestl in the 2nd round too. So half the hashes are fully evaluated now. It's faster in the end - this is what counts. Christian

What about Talkcoin he ah yes, NIST5 includes Groestl, too. I amended my posting.

Getting an extra ~1Mhash/s per 780ti card mining x11 (from 4.5Mhash/s to 5.5Mhash/s) with v1.1. A nice little bump

2 770's and an 670...
Groestl: Before: 17MH After: 24MH
NIST5: Before: 20MH After: 24.5MH

Jackpotcoin with 5x750Ti Linux, stock clocks: old ccminer: 19.5MH @ 310W new ccminer: 27.5MH @ 350W so it's 41% more hashpower for 13% power usage - nice

interesting: 780ti on jpc is doing now 11.5MHash and on nist5 17MHash/s 750ti 5.5MHash 8.2MHash/s
Actually the gap between the 2 cards also decreases (before it was around 2.5 now it is getting close to 2)

So, does this seem correct for one 750ti?: -X11:2.6MH/s -Jackpot:5.5MH/s -NIST5: 8.4MH/s -Quark: 4.7MH/s -Groestl: 8MH/s (!!!!!! was 3.1MH/s before !!!!!) I used these numbers to generate following list for one 750ti: http://pastebin.com/xcFqtX9EStill old hashrates for X13. Want to see Christian's magic first Again, this list is only a snapshot for this moment, with current prices and difficulties, so lower your own estimates.

My EVGA FTW cards come overclocked with tdp raised so i'm able to get 5.5 out of those with +10 core and +400 memory, but my MSI Gaming get close and most of my Gigabyte 750Ti's look like they're averaging 5.25. Could do more but everytime I use normally stable overclocks with ccminer it spits out large hash numbers and stops working again. Happens on any of my rigs so I know it's not hardware or anything else. I've seen most people here with that issue as well, but hey if there's a fix I'd love to hear about so I can just leave them at the perfect overclock.
