Hey Daniel,

Quote:
I agree with reducing the memory usage, BUT I do not think your code is ugly at all.


Thanks for this one.
I guess the code of an GPU-Chess-Programm must be a bit arbitrary Smile

Quote:
AFAIK you and I have been trying to use each core for doing real search. So unless you think it is impossible toreach full occupancy with the current method used, there is no need to waste cores for that purpose.


I totally agree with you.
I ve tested different approaches to get multible threads working on the same item but the one-thread-one-board design outperforms them.

...actually i am happy with the performance of Zetas Move Generator...looking forward to debug and enhance the search-algorithm....
