Hi all!

I made a fork of SPH-Sgminer for Groestl algorithm. See here: https://bitcointalk.org/index.php?topic=652849

If you have AMD GPU, please try it. I'm getting 16.2 MH/s on R9 290 and 7.56 MH/s on R9 270X.

In a few days I'll post 17.0 MH/s R9 290 kernel (I'll post update in this forum).

I'm planning to work on improving this miner in the future.

You don't need to specify difficulty multiplier anymore.

If you have any problems with this miner - please post directly into that forum.

PS: If you are on NVidia, you might want to check out ccMiner 1.1 (it just got got substantional speed increase for Groestl mining)

Thanks
