Concurrent testing, some cores are more equal than others

[Gabor Szots]

I have a CPU with 8 P and 4 E cores but I have disabled the E cores in the BIOS.

Wouldn’t it be nice if the test controller, cutechess or whatever, could manage to ensure that each matched game pair was carried out on either P core or E core. Then it doesn’t really matter about the core performance, since they’ll be balanced, and that’s all we need. Balance.

It can do it - but not on its own - as already explained.

Code: Select all

./c-chess-cli -each tc=0.3+0.1 -engine cmd="taskset --cpu-list 2 /home/christian/schach/c-chess-cli/PlentyChess-7.0.37-linux-ssse3" -engine cmd="taskset --cpu-list 3 /home/christian/schach/c-chess-cli/reckless-linux-generic-111225" -games 100 -openings file=/home/christian/schach/c-chess-cli/UHO_2024_6mvs_+090_+099.epd order=random -repeat -pgn neu-match-contest.pgn 3

You'd have to prefix a program (suitable for windows).
Case above: Third core and fourth core are exclusively used. Manpage explains how you can sort/specify. Engine-name could also be pointing to polyglot (which relies on an *.ini) and so on.

Is this really not solvable under windows?
