I tested Scorpio2.9.1 maddex and Stoofvlees a10.
a11 at the Moment has only 200 games. Results later.
TCEC hardware is not optimal for Stoofvlees. Here 5knps on a Gtx 1650. TCEC : 11 knps ?
I just saw the last two games of Stoofvlees II a 11 and its was hitting 12.6 knps which is twice more than with a GTX 1650, to me that is great, but Scorpion was hitting three times more, closer to 37 knps :shock:

Here is the Output of scorpio with my Card:
# nodes = 399689 <0% qnodes> time = 9060ms nps = 44115 eps = 0 nneps = 5183
# Tree: nodes = 64332 depth = 19 pps = 5172 visits = 46703
# qsearch_calls = 0 search_calls = 0
Daniel says nps does not mean much, I shall compare nneps. But TCEC shows the nps I think and I saw here 100-150 knps.
I thought TCEC uses much better grafic cards - so only 2x to gtx 1650 seems to be not great ??

Hi Werner,

Yes, nps is meaningless as it counts also nodes where NN evaluation is not done.
TCEC shows the nneps/pps value which are almost the same.The difference between pps and nneps
is that pps includes cached nodes counts so pps could be 2-3x greater when there is a ponder hit.
I think it gets on average 70knps and in endgames closer to 150knps there.

Are you working on a newer version of ScorpioNN?, since it will have very tough competitors when it reach Division P against Houdini, Komodo, Alliestein, and mainly versus Stockfisk, and LCZero, In TCEC

PS: How does the INT8 works ?
