Your approach has indeed been done for several decades.
It works at first, but then it becomes clearer that tuning for a test set is not the same as actual game strength.
Recall the early focus on WAC 300 scores...

Works just fine for me from a cmd window...

Is there a tourney manager that uses the higher precision timers?

I'm not on Windows anymore, but under Linux, c-chess-cli has very precise timing (via clock_gettime with monotonic clock).

Thanks, I have not tried that one yet.

I would be surprised if most engines would benefit from more accurate (i.e. msec) specification of the time on their clocks. The clocks they use for their own timing decisions typically also ticks only once every 16 msec. And scheduling delays would become very important at the msec level. You shou...

True. UCI wouldn't have this issue, but the Winboard side is CECP only. However, it doesn't make much sense to use a GUI for such fast games because the display will cost a disproportionate amount of time. It would make more sense to use a CLI solution. You may not know that Winboard has a no GUI o...

There are many different NN sizes and architectures.

The larger ones like Lc0 uses are only really practical on GPUs.

The smaller ones like SF-NNUE run on CPUs (and are very cleverly incrementally updated to make even faster).

This was just posted on the Discord: TilpsToday at 6:09 AM !2gpus Little TeapotBOTToday at 6:09 AM To run Lc0 on 2 GPUs: Specify the following UCI parameters: Backend: multiplexing BackendOpts: backend=cudnn-fp16,(gpu=0),(gpu=1) Threads: 3 OR add the following in command line: --backend=multiplexing...

I also have an old i920 that I was able to comfortably overclock to 4GHz (from 2.6GHz). Over the years I added more RAM, SSD, faster GPU (GTX770 to 1070 to 2060), etc. It was fine for most things. My even older Q6600 (also easily OC'd, but so old no popcnt) would get the "hand me down" components fr...
