Crystal 7 CMB

[Jouni]

Crystal 7? (name is Crystal dev) has bigger net and it's speed about 50% of Crystal 6. No wonder version version 7 is clearly worse in all test suites. I go back to version 6 .

I think I'll quit this forum.

One example. Arasan suite 15s and 6 cores. Crystal 6 solved 193/200 with time 4m29s. Crystal 7 solved 185 with time 6m42s.

Sometimes I get depressed seeing what computerchess is doing. Not just here of course.
If there is more content, there tends to be less noise. That is just a natural reaction. Always been like that. Please do not give up on Crystal! It really was a highlight and lighting up the forum to read about and use! Thanks Joseph for the new version!

Arasan- suite isn't difficult enough for engines like Crystal SMP on strong hardware with 15"/pos.
256 out of my old harder 128- suite and 128 from Dann's new one "pure.epd" with 15"/pos. and 8 threads (see end of Dann's thread about it way back then):

WDL with faster or one-sided solved ones = wins, one-sided not or slowlier solved ones = losses, rest draws, counted manually like this:



, and the numbers given into EolStat from the point of view of Crystal 7:

Code: Select all

Wins   = 76
Draws  = 142
Losses = 38
Av.Op. Elo = 3500

Also in difficult HTC suite and longer time control Crystal 6 was better and faster.OK I need probably faster CPU.
