Re: about the term of equal hardware
No you read the table wrong. The estimate of TCEC before the Div 4a was 3232, which was of course wrong by several hundreds of rating pointsj.korhonen wrote: ↑Sun Mar 10, 2019 4:49 pmAfter the completion of Division 4a live rating of Igel 1.2 is 3232 Elo on TCEC hardware https://cd.tcecbeta.club/archive.html?s ... =4a&game=1 (Tab Standings )CMCanavessi wrote: ↑Wed Mar 06, 2019 9:38 pmIgel is "at least" 2800-2900 on TCEC hardware.j.korhonen wrote: ↑Wed Mar 06, 2019 8:31 pmAnd what?

Such a unique engine as Zeta should be play in the TCEC
and also for most other programs of those 10 participants.

10 Igel 1.2 18 2.5 0 1 [1/0] 14 [6/8] 17.50 3372 -140 [3232]
Note that I only selected 1cpu versions for all (CCRL has only 1 and 4 anyway), but that doesn' matter
much for the order of programs, which is decisive. Adding a fantasy number to each program due to
TCEC hardware won't change it...
Even with 18 games only, Igel was clearly last, while seeded 'by lottery' clearly for #1 ;-)

Re: about the term of equal hardware
I've been inspired by this discussion to test Igel 1.4.1 (~2660) on a hardware that is close to TCEC and after executing 226 CCRL 40/40 games on the following machine:
Intel Core i7-6950X CPU @ 3.00GHz (10 cores, 20 threads)
128GB of RAM
In the following configuration:
Igel 1.3 (~2660)
Hash=16 GB
Threads=19
Tablebases: no
Book=Perfect2017.bin, 12 moves
against
GreKo 2018 (~2710)
Hash=1 GB (max for GreKo)
Threads=1 (max for GreKo since smp is not supported)
Tablebases: no
Book=Perfect2017.bin, 12 moves
I got pretty much a draw score.
P.S. I tried to attach a pgn file of the games but it tells me the file type is invalid???

Topple 0.3.5 (Vincent Tang) - 2700
Marvin 3.2.0 (Martin Danielsson) - 2850

let us assume the best software is those which makes best use of the transistors

18.6 billion transistors clocked with max 1.545 GHz
Nvidia RTX 2080:
13.6 billion transistors clocked with max 1.710 GHz
2*Intel Xeon E5-2699v4:

Even with the best black magic bit twiddling hacks you will be limited by

Re: about the term of equal hardware
Try putting them in a zip archive or a 7zip archive.
I guess that they are trying to save space by making us compress stuff.
You can attach archives and images. Not sure what else.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

In that case, (2) Intel Xeon E5-2699v4 (290W) vs (1) Nvidia RTX 2080 TI (250W) would be an interesting match with a bit of 40W disadvantage for the NN engine.j.korhonen wrote: ↑Thu Jun 06, 2019 1:56 amNvidia RTX 2080 TI: 250Wsmatovic wrote: ↑Sun Mar 03, 2019 12:46 pm Okay, another try,

Re: about the term of equal hardware
We can measure in watts.
We can measure in dollars.
We can measure in flops.
But we will always be comparing apples to oranges.
GPUs give enormous floating point operation counts.
GPUs are really, really cheap for the compute power you get.
GPUs use a lot of watts.
But these two systems play chess very, very differently.
I think that whatever it was they did for TCEC was pretty good.
The reason I say that is that the strength of LC0 and Stockfish was very similar.
So the contest was competitive.

...LC0 uses GPUs as neural network accelerators, simply cos they fit well for
this task and are relatively cheap for their performance. If in future there is
an alternative technique available to the end user, like TPUs, FPGAs, or even
Quantum Machines, then LC0 will use them too, regardless of how they compare
to CPUs.
