Unofficial World Championships Of Computer Programs Rapid 2019

[BertTuyt]

A match Kingsrow 1.60b - Scan 3.1 ended in a victory for Scan.
Match result, 2 wins Scan, 1 win Kingsrow, 155 draws (so around 2% of the games decisive).
Thinking time 1 minute, 6 cores each, no pondering.
Max speed Kingsrow 80 MNodes/sec, Scan 40MNodes/s.

Based upon statistics no reason to state that the one is better.

Settings Scan:
variant = normal
book = true
book-ply = 4
book-margin = 4
threads = 6
tt-size = 24
bb-size = 6

Settings Kingsrow:
Search Mode Normal
Hash table size 256 MByte
DB Cache 30356 MByte
7p DB

Attached pdn file.

Thank you, Bert. I have a question for you (because I'm interested). Does this show you any program " Max speed Kingsrow 80 MNodes/sec, Scan 40MNodes/s."

[BertTuyt]

I don't understand your question, but let me answer it this way.
Both Kingsrow and Scan show the speed, Kingsrow in the bottom in KN/s, with Scan you can also see the output (it is the number before the pv (principal variation).

In Scan you can activate output in DXP mode with dxp-search = true

dxp-server = true
dxp-host = 127.0.0.1
dxp-port = 27531
dxp-initiator = false
dxp-time = 3
dxp-moves = 75
dxp-board = true
dxp-search = true

See attached screenshot for Kingsrow where the actual speed was 80,290 KN/s (= 80.2 MN/s)

Thank you for your answer Bert. Now please play the match Kingsrow - Damage.

[BertTuyt]

I'm now doing another Kingsrow - Scan (now with 2 minutes/game).

Will try to find the time during the week.
As the next 2 weekends I'm traveling.

Will keep you posted.

Hi Bert.

I am puzzled by your Kingsrow result 80,290 KN/s . You must have some super-computer.

[BertTuyt]

I have a i7-8700K with 6 cores, running between 4.3 GHz - 4.5 GHz.

And today there was an announcement from Intel.
The new Cascade Lake-X processors, see below.
So multi core is going mainstream.

Code: Select all

Intel Cascade Lake-X
Processor 		Cores/threads 	Clock 	All core-turbo 	Turbo Boost 2 	Turbo Boost 3 	Tdp 	Price
Core i9-10980XE 	18/36 		3,0GHz 	3,8GHz 		4,6GHz 		4,8GHz 		165W 	$979
Core i9-10940X 		14/28 		3,3GHz 	4,1GHz 		4,6GHz 		4,8GHz 		165W 	$784
Core i9-10920X 		12/24 		3,5GHz 	4,3GHz 		4,6GHz 		4,8GHz 		165W 	$689
Core i9-10900X 		10/20 		3,7GHz 	4,3Ghz 		4,5GHz 		4,7GHz 		165W 	$590

I have a i7-8700K with 6 cores, running between 4.3 GHz - 4.5 GHz.

Bert

My xeon e5-1650 v4 runs at 3.6 GHz - 4.0 GHz and reaches 69.8M nps in the opening position.

[BertTuyt]

Is that a 4 core Rein?

Bert

[Rein Halbersma]

Is that a 4 core Rein?

Bert

No, 6/12 cores/threads, just as its predecessors (v1-v3)

[BertTuyt]

Rein, ok than your speed is totally in line with mine.
Can you imagine the nodes/second, on a water cooled 4 GHz 18 core processor ?
