We have made some very fast progress before that release and we have also had a lot of progress in the last couple of days. That's why we want to publish Koivisto 2.0 today. Besides adding Lazy SMP which scales nicely up to 8 threads and beyond, we fixed a few bugs, improved the speed, and many more things as listed below:

The easiest way to contact us would be our Discord: (Finn) Luecx#0540 or (Kim) ChiefWiggum#1154
(I noticed that on my slow old hardware Koivisto 2 runs now at around 740kn/s compared to around 600kn/s for version 1 - checked for startpos)

We should perhaps adjust the makefile for those type of hardwares. On my hardware, Koivisto gets about 2.5Mnps there.
Let's say around depth 25-30, here it is around 640 kn/s.

Re: Koivisto 2.0
(Edit: With 'vanilla' I meant the available compile for your hardware)
You should try the fastest compile of SF11 for your hardware, except you don't have used an optimized compile of your Koivisto yourself,
otherwise the comparison is not too precise, so you should try 'modern' or 'bmi2'.
Code: Select all
SF11 Koi2
2.5 / 1.8 = 1.389
0.74 / 0.64 = 1.156

Re: Koivisto 2.0
Oh my bad! SF modern gets about 2Mnps on my hardware. So that would be a ratio of 1.2. I guess thats alrightGuenther wrote: ↑Wed Sep 09, 2020 3:24 pm(Edit: With 'vanilla' I meant the available compile for your hardware)

Re: Koivisto 2.0
My compilation I guess? So it seems it is fine.

Re: Koivisto 2.0
Yeah I guess its fine
As long as its slightly faster than most other engines, it should be fine

Wow, nice! Thank you very much It would also be really nice if Kim Kåhre would be added as an author because we both did the same amount of work
Furthermore, we only do check extensions when SEE > 0.
