Lazy SMP gives better Elo, but clearly does not get as deep as quickly.
The new Stockfish loses several plies in the same amount of time on an hour search compared to the traditional search version.

Re: parallel search speed measurement
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: parallel search speed measurement
I don't understand why Lazy SMP gives better ELO. According to this test with Arasan 19 testsuite, the effective speed-up is worse than that of Crafty 25. Depth is irrelevant, as for Komodo and Stockfish I just counted the number of solutions and time to solutions. It is possible that tactical testsuite approach is wrong.Dann Corbit wrote:Lazy SMP gives better Elo, but clearly does not get as deep as quickly.
