Zeta, (Zeta OpenCL Chess)
an experimental open source chess engine by Srdja Matovic, written in OpenCL. The engine has been in development since 2010 and was first released July 13, 2011 under the GNU GPL.
Zeta supports only some basic commands of the Chess Engine Communication Protocol aka WinBoard and XBoard.
It features Quad-Bitboards, and its ability to run on a GPU.
Details
Zeta is written in C (host) and OpenCL (device). The host handles the IO, but all chess related computations are done in OpenCL on the device. Zeta v097 and v098 were designed to run thousands of independent threads on a GPU, therefore they store the expanded search tree via an randomized Best-First-MiniMax search in memory .
