Of course too few games to make clear statements, but it seems that Texel scales well on 60 cores compared to 12 cores.
I see 40+ at best in Fritz GUI. No way in H-E-Double hockey sticks will it show 800 BUT you could edit the UCI file IF you knew all the parameters and put them in.Damir wrote:Is there some kind of software that will make all 800 parameters visible in Fritz GUI ?![]()
I don't know how either Jonny or Texel scales on a large cluster. Texel is around 250 elo below Houdini 6 though on CCRL 40/40. The 100 elo reported earlier in this thread was in special endgame positions when TBs were in use.main line wrote:What is strongest:

time control 40/120 min + 20/60min + 45min
If Texel is 120 Elo below top 3 programs in PC with same cores, maybe Texel can be better than Houdini, Komodo or Sf, used by cluster of huge cores for ex. Texel 128 cores against Houdini 12 cores?
At that TC doubling of cores on a cluster can hardly be worth more than 25Elo. Going from 12 to 128 cores is 3.2 doublings or around 80Elo at best.main line wrote:What is strongest:

I think you are probably right about that, but it would be fun to see such a contest anyway.Milos wrote:At that TC doubling of cores on a cluster can hardly be worth more than 25Elo. Going from 12 to 128 cores is 3.2 doublings or around 80Elo at best.main line wrote:What is strongest:

Going from 64 to 2000 cores is 5 doublings but with so many cores that is probably worth less than 25Elo per doubling, i.e. most probably less than 120Elo in total. So no, neither Johny nor Texel are stronger than Houdini with 30 times more cores.
I do not think anything significant can be discovered by a tiny contest like Leiden.main line wrote:But we saw this here:

I am sure in one thing:
Texel with 2400 cores in such time control ~1hour45min/game + increment 15sec/move is unbeatable because with huge number of cores and in long time control engine will find strongest ("God's") move in any position.
No difference between 2000 cores and 10.000 cores or 100.000 cores because for strongest move in any position with nowadays strogest engines need probably 2400 cores 2-5 minutes / move.
I see no reason to believe that programs will find the strongest move in any position in the near future even if you give them 24 hours per move but note that you do not need it in order to be unbeatable because you need only to find moves that are good enough not to lose in practical game.main line wrote:But we saw this here:
