which coins use this algorithm? i see they call it "marucoin" algorithm in sph-sgminer, but is marucoin the first coin to use it or only the most famous coin?
Yep it's marucoin. it's the same as X11 it just has 2 additional sph algos (hamsi and fugue). By the way, once you earn enough from the donations (which I have nothing against), consider contributing some of your improvements to sgminer (
https://github.com/sgminer-dev/sgminer/tree/v5_0). Since it would not be possible to do this without sgminer (or cgminer in the first place), it is nice to give something back from time to time. Cheers!
are you one of the developers for the original sgminer? I'd like to ask some questions about the current opencl implementation of x13:
1- The code is based on SPH code, and as such has several tuning parameters, mainly "SPH_HAMSI_EXPAND_BIG" from 1 to 8 and "SPH_HAMSI_EXPAND_SMALL" (not sure about the valid range). Have you experimented with all the values before choosing "SPH_HAMSI_EXPAND_BIG=1"?
I'm asking because I did some experiments with Groetsl and figured out that the current parameters were actually the best ones, and didn't want to loose time with something that has already been tested.
