Great representation. Thank you very much!

[tpoppins]

No, thank you Andreas for all the cool tests you've done over the years. After your Stockfish - Initial position, MultiPV Mode=20, Depth=50 post I had an idea to do this very test but suspected you had it in the works already. I would only suggest a much larger hash (at least 8 GB) as an improvement, but few laptops have that much RAM.

BTW, have you ever done a scaling test for speed with NPS rather than MHz as the measure of speed?

Thanks for your kind words. 1.d4 MultiPV Mode=20, Depth=50 is currently running.
For such tests I use older laptops. Unfortunately they have usually just 2 or 4 GB of RAM.

BTW, have you ever done a scaling test for speed with NPS rather than MHz as the measure of speed?

Do you mean such a test?
http://www.talkchess.com/forum/viewtopic.php?t=54133

[tpoppins]

Yes, thank you. That brings up the main question: have you run any test to establish if there is a direct relationship between NPS and Elo? I suspect the connection to be tenuous, but it would be interesting to see the results.

[fastgm]

Yes, thank you. That brings up the main question: have you run any test to establish if there is a direct relationship between NPS and Elo? I suspect the connection to be tenuous, but it would be interesting to see the results.

No I haven't, but I think there is a relationship, depending on the time control.
For example:

Code: Select all

Stockfish 9 - nps=1.000.000 - tc=10+0.1 sec - Elo = 3000
Stockfish 9 - nps=2.000.000 - tc=10+0.1 sec - Elo = ?
Stockfish 9 - nps=3.000.000 - tc=10+0.1 sec - Elo = ?
 
Stockfish 9 - nps=1.000.000 - tc=20+0.2 sec - Elo = 3000
Stockfish 9 - nps=2.000.000 - tc=20+0.2 sec - Elo = ?
Stockfish 9 - nps=3.000.000 - tc=20+0.2 sec - Elo = ?

But is there a way to test this? We can measure the nodes per second on one thread, two threads, etc. in a certain position. Or we can calculate the average nodes per second from a match at a certain time control. The LittleBlitzer GUI can do this.
Is there a way/tool to limit an engine to a certain number of nodes per second?
