'''Zeta''', (Zeta OpenCL Chess)<br/>
an experimental [[:Category:Open Source|open source chess engine]] by [[Srdja Matovic]], written in [[C]] and [[OpenCL]]. 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 [[Chess Engine Communication Protocol|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 [[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
