TwistedLogic 1 CPU - Rybka Cluster 52 CPUs - [1/2 - 1/2]

Post by swami »

TwistedLogic is still single CPU, running on my Q6600. Edsel has been working on MP, sadly it couldn't utilize the extra cores in the tournament.

Book played a major part in this. Also, Rybka was searching faster, playing quicker and not thinking for too long after it was out of book. I assume that's how the pondering in a cluster is. Maybe the position was dead draw after it was out of book for Rybka?

TwistedLogic's score was dropping slightly but regained after enough piece trades.

Congrats to the bookmaker Audy Arandela, and ofcourse the author Edsel Apostol. :D

I guess this was the position after the last book move:

[d] 8/1b1n1k2/p1p1p1rP/1p3p2/5P2/2N5/PPP1R1P1/2K2B2 w - - 0 21

Indeed congrats to Edsel and looking forward to see his SMP version from TL!

A draw with 1core against 52cores...must give him a boost and motivation to make TL stronger and stronger!

Actually rybka is running on 56 cores: five Nehalem EP octals, 4 W3520 Xeons at 4.2 GHz.

With best regards,

Thanks.

The version of TL used here is 20090721. The current development version is 20090817 and I'm currently tuning the parameters. I will release it within two weeks after we've found the best settings.

SMP is not yet working. I will release it too after I could make it work correctly.
