What is ChessBrain?

ChessBrain is a virtual chess supercomputer using the processing power of Internet connected machines.

On January 30th 2004 ChessBrain made history by becoming the first distributed network to play a game against a single human opponent.

Project Status

ChessBrain in German Linux User Magazine

The ChessBrain project was mentioned in the October 2002 issue of the German "Linux User" magazine. The article was entitled, "Chess with Cluster Power".

The article also ran in English at: Linux-Magazine

Oliver Otte (ootte) brought the article to our attention. He offers the following translation:


The successes of computers like Deep Blue or Deep Fritz (that will compete with 8 processors against the acting (BGN-)chess world champion Vladimir Kramnik in october) showed that computers with appropriate power can't barely be beat.

The possibilities of a high-performance chess computer is researched by the relatively young Chessbrain-Project,
which reached the first of four propagated development stages recently. But ChessBrain ought to become a real chess rival not until Phase 3. Currently the main focus of work is the distributed infrastructure. What is interesting about this project is the use of the protocol SOAP, to transfer data to the clients (so called
PeerNodes). Because FlashMX can handle SOAP ChessBrain offers viewers (besides the PeerNode software), that bases on Flash or PHP - to allow tracking of the actual game. Being a participant yourself just makes sense if you are a flat rate user [annotation by me: dial-up account with a monthly bill, no fee per gigabyte or online hour], since the PeerNode constantly accesses the server.
