The Rybka Cluster was initiated in September 2008, when an initial version was built just in time to participate in the 2008 ICGA World Computer Chess Championship in Beijing. The first results were promising and steady improvement in both software and hardware ensued. By December 2010, the Rybka Cluster had evolved into a polished chess analysis tool.
Cumulative figures (as of December 2010) include:
- 2,000 hours of remote client logins
- 4,000 hours of direct cluster testing
- 60,000 hours of software-simulated cluster testing
- 12 major computer chess tournament wins in 12 attempts, including 2 ACCA World Championships and 3 ICGA World Championships
