Re: Laser 1.6 Release
Thanks, Jeffrey.
My testing says your last few time control changes have a big impact at STC

Re: Laser 1.6 Release
Hi Jeffrey, I've benchmarked all 3 versions and something looks suspicious with the BMI2 and the Popcount version. They have almost the same speed, which on a Ryzen processor is kind of nonsense due to the BMI2 bug, so either the BMI2 is not using BMI2, or the Popcount version is also using BMI2 and running slower than it should. The Nopopcount version is the slower of them all, as expected. Usually with other engines, the Popcount version is much faster. Maybe you can check that, or others can also test and see if they find the same?jeffreyan11 wrote: ↑Sat Jul 14, 2018 9:28 pm Laser 1.6 has now been released and is available at

Re: Laser 1.6 Release
Laser does not have BMI2/PEXT support in the sense that most expect. Usually this implies replacing the multiplication shift and step of the magic bitboard computation with a single pext instruction. Jeffrey has not done this. Here is this BMI2 support patchCMCanavessi wrote: ↑Sun Jul 15, 2018 4:59 pmHi Jeffrey, I've benchmarked all 3 versions and something looks suspicious with the BMI2 and the Popcount version.

, which just assumes you have haswell architecture, which is still a speedup I presume.
