Re: Core behaviour
Further CPU scheduling tests can be followed here.

In addition I changed the number of games to 16,000 and the TC to 40/5+0.1.Rebel wrote:Further CPU scheduling tests can be followed here.
Dani (and others), how do you usually test, time control and number of games?

Re: Core behaviour
My usual testing is at 15+0.04 for stc sometimes less, and ltc ranges from 30+0.04 to 80+0.05.Rebel wrote: Dani (and others), how do you usually test, time control and number of games?
The number of games varies depending on how well is going, so similar to using SPRT but as the test runs on 5 computers at the same time, I caculate when to stop roughly by eye. Sometimes I just resume the test if I'm not convinced. Also when I'm trying to see if a patch scales well by time, I tend to do more games to be more sure that is not just luck. Most tests are between 15000-35000 games.

Re: Core behaviour
I have measured it for ProDeo, 5% faster in nodes.cdani wrote: I suppose that any high performance software will profit at least a little from the cpu scheduling, isn't it?
Code: Select all
Affinity 16:05:57 (119.360M nodes) NPS = 2.059K
Normal 16:09:42 (113.690M nodes) NPS = 1.954K
Depth Stats MIDG END0 END1 END2
Affinity 10.72 11.29 12.18 15.22
Normal 10.63 11.21 12.12 15.12

Re: Core behaviour
An amazing result of 53.9% (+27 elo) [Andscacs+affinity] vs [Andscacs without affinity]. See: http://rebel13.nl/misc/scheduling.html
Comments c.q. issues to discuss.
1. I wonder if the setup of the match is fair in the sense the [Andscacs+affinity] version is perhaps hurting the performance of the [Andscacs without affinity] version.
2. 40/5+0.1 is ultra fast and perhaps favors the [Andscacs + affinity] looking at the depths comparison.
Anyway, reason enough to test
[SF4+affinity] vs [SF4 without affinity]
[Komodo 5 + affinity] vs [Komodo 5 without affinity]
first.
And see if they produce similar results.
