**[[Home]] * [[Engines]] * Zeta** || [[image:zeta.png align="left"]] ||~ || **Zeta**, (Zeta OpenCL Chess) an experimental [[Open Source Engines|open source chess engine]] written in [[OpenCL]] by [[Srdja Matovic]]. The engine has been in development since 2010 and was first released July 13, 2011 under the [[Free Software Foundation#GPL|GNU GPL]]. Zeta supports only some basic commands of the [[chessprogramming/Chess Engine Communication Protocol|Chess Engine Communication Protocol]] ([[Winboard]]/[[Xboard]]). Main features are the use of [[Quad-Bitboards]], and its ability to run on a [[GPU]]. || || Zeta Logo ||~ ||^ || [[toc]] =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 [[Thread|threads]] on a [[GPU]], therefore they store the expanded search tree via an randomized [[Best-First]]-MiniMax search in [[Memory|memory]] . =NPS and Playing Strength= * Zeta 098c on Nvidia GeForce GTX 480, ca. 5 Mnps, est. 2000 Elo * Zeta 097x on Nvidia GeForce GTX 480, ca. 5 Mnps, est. 1800 Elo * Zeta 098c on AMD Radeon R9 290, ca. 3.2 Mnps * Zeta 097x on AMD Radeon HD 7750, ca. 800 Knps =See also= * [[Zeta Dva]] =Forum Posts= * [[http://www.talkchess.com/forum/viewtopic.php?t=33315|Zeta, a chess engine in OpenCL]] by [[Srdja Matovic]], [[CCC]], March 17, 2010 * [[http://www.talkchess.com/forum/viewtopic.php?t=39459|Zeta plays chess on a gpu]] by [[Srdja Matovic]], [[CCC]], June 23, 2011 * [[http://www.talkchess.com/forum/viewtopic.php?t=62288|ZetaOpenCL 098ew64 running on Windows OS]] by [[Norbert Raimund Leisner]], [[CCC]], November 27, 2016 * [[http://www.talkchess.com/forum/viewtopic.php?t=63719|Zeta v099a, gpu chess update]] by [[Srdja Matovic]], [[CCC]], April 11, 2017 =External Links= * [[https://github.com/smatovic/Zeta|GitHub - smatovic/Zeta: Experimental chess engine written in OpenCL]] * [[https://web.archive.org/web/20140604141114/http://zeta-chess.blogspot.com/|Archived Zeta Chess blog]], [[http://en.wikipedia.org/wiki/Wayback_Machine|Wayback Machine]] =What links here?= [[include component="backlinks" page="page:Zeta" limit="60"]] **[[Engines|Up one level]]**
