Hey Daniel,

just want to mention that i doubled my move gen performance simply by using a vector datatype "long4" for the QuadBitboards.

Running a simple loop with the starting position i get about 300Knps per SIMD Unit,
if i turn of legality check it is up to 1Mnps.

How does your move generator perform?

Srdja


You're buliding a chessprogram on a gpu as well Srdje?

Can you remind us which gpu you're using Srdja and how high it is clocked?

AMD has 64 pe's per SIMD and Nvidia has at Fermi around 32 streamcores per SIMD.

SIMD also gets called compute units by the way, for those who wonder.

The tesla's i've here are 1.15Ghz it seems, 448 cores and 6GB ram.

Regards,
Vincent
