If an engine supports multiple threads, it can use multiple cores of the processor. If you don't give a configuration command to the engine, it will use whatever it thinks should be a good default, and that can well be "use all cores".

From experience, people who use open source libraries (with truly free licenses) in their closed source programs often create PRs to help fix/add new features. The GPL doesn't prohibit making PRs. And that is no "true" freedom because the added freedom of these leechers is just the missing freedom ...

Closed source is a freedom of choice as well The GPL doesn't prevent that choice. You can make closed source all day long. It's just that you can't take GPL software for that and reap where otheres have harvested. How exactly does closed source harm you? Closed source itself doesn't, but the inhere...

It takes 800ms to generate these bitbases on my pc. Marcels generator takes a few milliseconds: https://github.com/kervinck/pfkpk Is it worth using KPK as precomputed ? why not on the fly ? I've baked the resulting bitbase into my engine because my target platform has a lot of free ROM, but not RAM...

It's still not compliant with the GPL because the GPL doesn't just refer to the source text and building oneself, it refers also to the binaries. You have to be able to give the binary to anyone else on any (compatible of course) device. That is still not possible with the binary from the store. Bes...

I forgot another hurdle for iOS, and that's more serious. The usual partitioning of GUI and UCI/CECP engine is not possible under iOS, that has to be baked into one package. That's because installation is only possible from Apple's app store, and Apple doesn't allow programs that start other program...

Check in the App Store: it’s under the GPL. No mention of any other license is made. It is in violation of the GPL. See here why: https://www.fsf.org/news/2010-05-app-store-compliance Just as with GNU Go, any spoilsport, not just the authors, can contact Apple and get stockfish yanked from the App ...

How do you explain the existence of the GPL’d stockfish in the App Store? By the agreement of all Stockfish authors to tolerate the GPL violation that the additional store limitations cause. Effectively, the Stockfish team is dual licencing Stockfish. They have that right, but in order to do that, ...

One of the problems with iOS is that installation can be from Apple's app store only. Developer membership costs 99 EUR per year, and more importantly, Apple made its store incompatible with any GPL version. LC0 happens to be under GPL 3, so that wouldn't work unless all LC0 authors would agree to d...

other ideas are welcome too of course

Is the full parsing and evaluation of engine specific UCI options already implemented? If not, that would be a nice feature.
