[Ferdy]

To save time, instead of HT off, I am playing now with HT on and game concurrency of 6 on my 8-logical core processor.

The TC of 60m + 10s is now 75m + 10s and TC of 90m + 30s will become 100m + 30s.

To save time, instead of HT off, I am playing now with HT on and game concurrency of 6 on my 8-logical core processor.

I think it's not good : if a thread runs on a core who use HT, it gets only 75% of the core speed. If it's opponent runs on a core who doesn't use HT, it gets 100% of the core speed.

I just let the OS manage it (turbo boost off), also tested this and have not seen any problems, a stronger engine is a stronger engine and a weaker engine is a weaker engine. Also tested exactly the same engine and they can perform 50% too.

[hgm]

I think it is ot wise todo this with 6 out of 8 threads, as then most of the time 4 engines will share a core, while two will have a core to themselves. Better use 8 threads, then at leastthey will all be on equal footing.

I can run it at 7 especially when I am not using it, i.e overnight.

[hgm]

Then there still would be one engine that gets a full core, while the other 6 have to share one.It is difficult to predict how the OS will handle this. E.g. whether it will change the engine-to-core assignment fast enough so that it averages out.

Of course you could define affinities between engies and cores. If you assign matches 1-6 to virtualcores 1 to 6, virtual cores 7 and 8 (one physical core) would be left idle to handle other tasks.

There are other processes that are using the cpu including the GUI itself. This is why I prefer letting the OS managed it.

I have not tried using affinities yet, one of these days I will try to experiment it, and if I get stable results, I may go for it.

[Ferdy]

Condition changes:

VI Match GUI
1. Cute Chess
2. Concurrent games are set to 6 and engines are run on logical cores 2 to 7.
3. Draw adjudication is set to off.
4. Resign adjudication is set to off.
5. Ponder is set to off.
6. Opening suite depth is set to 100 plies.
7. Opening suite opening order is set to random.

After some tests, affinities looks fine in my system, so I will be using it.
