Re: SPCC: Testruns of Slow Chess 2.2 and Rubichess 1.7.3 finished

From now, all engine-binaries are popcount/pext/avx2, of course, because bmi2-compiles are extremly slow on AMD. To keep the rating-list engine-names consistent, the "bmi2"-extension in the engine-name is still in use for older engines - otherwise ORDO will not calculate all played games by this en...

Re: Looking for automatic Engine Testing Software

Cutechess-cli provides the functionality to run matches, with many options. OpenBench uses cutechess-cli for that layer of functionality but adds a UI on top and coordination across multiple machines, among other features. There is some basic documentation for it on the Github page. See "Engine Com...

Re: Ethereal & Schooner seems to be "Big Monsters"

1. The 203 move problem. Very often after 203 moves (without resign mode, Shredder GUI, have a look in the tournament rules) the game ended for Schooner and Shredder GUI crashed. Frank Might be worth noting that a typical uci string of "position startpos moves ..." followed by 203 moves by both pla...

Re: GCC 8.1 vs GCC 10.1

my experience is that gcc compiles are worse and more bloated than they were with older versions. Somewhere iaround GCC 4.6 we reached the golden age of gcc, we went downhill ever since, whereas LLVM is stronger than ever. I too have had the same experience, although my "best" form is GCC4.8. For a...

Re: Java vs C. It's not like one would think.

And this is the amazing part! An interpreted language is only 30% slower. I think, this is the result of a great runtime-optimization, something a rigid machine code cannot do. I find it more likely that slow-java practices translated themselves directly to C, and that the "small" speedgain is hind...

Re: Xiphos x Ethereal: Who has the best style?

look at the actual games and critique them from a stylistic point of view. Do you really think you, or anyone else, is capable of viewing a large enough sample to be able to determine a change in (alleged) style from a change that ultimately impacts an engine by a few elo? Its not like people are r...
