Re: McCain v10 Release

The obvious "idea" would be to create a Leela-SF hybrid, the tricky part being how to combine them. I can imagine Leela doesn't need all the CPU cores so the AB engine might check for blunders and perhaps take over in endgames, while Leela excels at openings/midgame. Also whenever AB engine finds a ...

Re: Basic automated testing

My instance is running here http://chess.grantnet.us/index/ , if you want to get an idea of the work flow. You would be able to connect any of your machines, and the results will be collected together. Time controls will be scaled per CPU, IE in the case that one machine is faster or something of t...

Re: Basic automated testing

I'd recommend OpenBench . Interesting, what does this OpenBench do exactly? It seems like a wrapper on top of cutechess-cli with some client-server functionality. If it allows me say to test on say two quads at the same time + gather the results then this would cut my testing time in half, which so...

Re: 32-core 3.3 Ghz Arm CPU

It is possible that both kernel and drivers are native on ARM, I don't know, the emulated x86 apps however, run very slow. Here are some benchmarks from emulated and native apps on a snapdragon 835. https://www.techspot.com/review/1599-windows-on-arm-performance/page2.html Anyway, why would you wan...

Re: 32-core 3.3 Ghz Arm CPU

Microsoft emulates x86 on ARM, there are already a few laptops with ARM architecture running this, the problem is that it runs so slow that it is not very usable in practice. Emulated x86 apps will be slow for sure (my guess about an order of magnitude even if JITted, just the cost of emulation its...

For now, I don't think Windows 10 runs on ARM architecture.

Re: Multithreaded batching on GPU for montecarlo and also alpha-beta

Does anybody know the exact difference between sched_yield() and usleep(0) or in windows Sleep(0) and SwitchToThread()? I don't know about Linux, but there's an attempt to recreate open source version of Windows (including kernel) called ReactOS. I'm not sure how much it resembles Windows kernel/sc...

Re: Texel tuning speed

Pawn cache helps, no doubt about that, I use it as well in my tuner. Your numbers indicate a speedup of 8% ((71.1-65.4)/71.1) for enabling eval cache. Ok, measurable at least but we can agree on the "not so stellar" :-) I think we can agree that the speedup would be 9% if you round properly :) Anyw...
