In preparation for the 2010 Chess World Championship, grandmaster Veselin Topalov rented time on a Blue Gene/P supercomputer installed in Sofia, the capital of Bulgaria, and operated by the Bulgarian Academy of Sciences and the Sofia University. Since there was no chess software for this supercomputer, Topalov hired computer engineers to modify existing chess programs for use on it.
“During my preparation for the match, my manager, Silvio Danailov, and I decided to approach something non-standard and to seek additional resources to increase the advantage over my opponent. It turned out that there is such a possibility. We found that in Bulgaria is installed and running one of the most powerful supercomputers in the world—Blue Gene/P of IBM. And because the computers and the chess software are necessary components in the preparation of the modern grandmasters, we decided to use the vast computational power of this machine.”
