Cluster Toga/Paderborn championship

[ChessAddict]

Anyone know where to get this engine or know anything about it? Maybe it's a type of the "Toga" engine. It placed third behind Rybka and Hiarcs at the Paderborn 2007 championships.

From the Rybka forum:

Indeed, Cluster Toga is a legal and fully legitimate cooperation between Fabien, Thomas and Kai. This is the good side of open source.

Hard to see it as a "good side of open source" when it's not even open source.

isn't it complete Toga which is open source?

They modified Toga to work on large numbers of processors, and as of now have not released the source to their modifications. So that's why it's not open source.

Simply put, they are not allowed to do that.
Toga is GPL, because Fruit is GPL and so Cluster Toga *must* be GPL.

This is correct, but it doesn't quite imply that Cluster Toga must be open source. The GPL states that if you distribute a program based on the original GPLed source code to someone -- even if it is just to a single person -- you have to give that person access to the full source code, and allow her to freely redistribute the source code or any work based on it.

In other words, as long as Kai only uses his tournament to participate in tournaments, he has no obligation to make his modified source code available to the public.
