28th International Open Dutch Computer Chess Championship
Leiden, The Netherlands, November 2008
In another exciting tournament held in Leiden in The Netherlands, HIARCS was again the top single computer but ultimately came second to a 40 core 5 computer cluster. HIARCS performed very well throughout the tournament.
HIARCS was running on a single 8-core computer and it's only defeat was to a 40 core, 5 computer cluster "super computer".
big thank you to Harvey Williamson for his extensive preparations before the tournament and travelling to The Netherlands to operate HIARCS. Many thanks also to Sebastian Boehme for his book preparations and Rob Osborne for allowing use of his 8 core SkullTrail hardware.
The list of hardware used by each contestant was as follows:
Rybka 3: 5x 8 core SkullTrail (using 40 cores)
HIARCS X: 8 core SkullTrail 4Ghz
Deep Sjeng: Venom 9650 4 core (except against HIARCS X where Deep Sjeng used a 11 core cluster!)
Hermann 2.4: Core 2 Duo E6600
Ktula 9: Quad 3.8Ghz AMD using only 1 core
The King: Dual Core
The Baron: AMD Dual Opteron 270 (4 cores) 2Ghz
Pandix AI 2008: Centrino 2Ghz
Joker: Core2 Duo 2.4Ghz using 1 core
Tzunami: Quad Q6600
We started the tournament with the risky 12.192 version and after the first round draw with The King we swapped to the tried and tested 12.153 version which was used to good effect in Beijing China.
The critical game for HIARCS was the defeat against Rybka and this effectively decided the tournament. Overall, HIARCS played the tournament well and we intend to come back even stronger next year.
