@bubus Update info regarding my effort of making fast Yespower 1.0 miner for Nvidia GPUs.

In recent weeks, as Yenten transition to new algorithm gets closer, I worked hard on my experimental prototype of Yespower 1.0 Nvidia GPU miner for all its N, R variants programing all sorts of optimizations to my Yespower 1.0 CUDA kernels. Several times I even rewriten my Yespower 1.0 CUDA kernels, redesigning algorithmic approach and even with all of this effort, with tons of time and optimization work I spend on it, the fastest where it managed to reach is 550 H/s (550 hashes) on one single 1080 Ti at Yespower 1.0 N 2048, R 32. Similar for N 4096, R 16.
It's waaaaaay tooooo slooooow.

So, I can basically say that if Yenten wants to be CPU dominant coin than Yespower 1.0 is indeed a great choice to stick to!

It's very unlikely that GPUs will be able to overtake Yespower 1.0.
Optimization techniques, tricks and CUDA speed-ups that work great for Yescrypt and other mining algorithms are basically useless for Yespower 1.0.

Despise being skeptical now for fast Yespower 1.0 on GPU, I still have more ideas in my mind about more approaches how to proceed to Yespower 1.0 on GPU which I haven’t tried so far.
Of course, as I said the last time, it is always very hard to predict hashrate of certain algorithm and various optimizations in advance – without actually implementing and running them.
Those will again require tons of programing effort and time with questionable outcome, but anyway, I actually like things like that.
When things don’t go as I expected, it gives me more strength to the challenge to find some way how I will finally twist neck of that Yespower 1.0 on GPU, one way or another. :grimacing: :smile: :wink:

But to be objective, the outcome is that Yespower 1.0 seems to be so bullet-proof algorithm that probably not even in years from now it will be dominated by GPUs, not even by the highest-end future GPUs.
