Hi Larry,
How old is the hardware you used for this,
I started another testrun with slightly other conditions concerning book. I used a fix testsuite (SilverSuite) now instead of Frank‘s actual FEOBOS-Book and added some more opponents, still 1400 games „only“…
For this run I used five computers:
AMD Ryzen 5 1500x @ ~3,7 GHZ (standard is 3,5) => 300 games/perf. ~3394
AMD Ryzen 5 1600 @ 3,5 GHZ (standard 3,2) => 300 games/perf. ~3360
AMD Ryzen 7 2700 @ 3,5 GHZ (standard 3,2) => 400 games/perf. ~3380
Intel i7 4770 Haswell @ ~3,8 GHZ (standard 3,4) => 200 games/perf. ~3340
Intel i5 6600k Skylake @ 4,0 GHZ (standard 3,5) => 200 games/perf. ~3345
All with AVX2-compile. I allways test previously which compile is fastest on the particular machine.
The overall result (performance) was a bit better, around 15-20 points. The testruns are hard to compare though, as I do not know anymore on which computers the first run was played. Definetely not on all these machines, I‘m sure about that at least.
My impression is – with a huge amount of uncertainty due to much too few games – that scoring on older Intels is a bit worse than on middle old Ryzen 5/7. The problem is: These two Intels are considerably faster than the Ryzens with nearly every engine, even with Komodo Dragon „default“…
On Haswell and Skylake BMI2-compiles normally are a bit faster, but in a 1-digit percentage range only, so without relevance. Random noise...
were there any crashes
No, not a single one and no time forfeits too. Komodo is one of the most stable engines I know
At the moment, I can only imagine that different GUIs are somehow the problem, though they shouldn't be.
Never ever, Larry. In this case Komodo would have a severe bug, but not the complete engine, only one part of the engine (MCTS)?! Activating the MCTS-checkbox causes problems with the GUI, but not with everyone?? And even if so, do you REALLY think this could make a difference of 50, 80 or 100 points? Sorry Larry, really no offense meant
, but that‘s nonsense.
BTW: I use same interfaces as Werner, i.e. Shredder Classic 13 and Arena 3.5.1, never had problems. Can't talk about LittleBlitzer or cutechess. Never used here and no reason to do so
