Eternity2.net
Eternity2.net is an exciting new project that uses Internet-connected computers to try to solve the EternityII™ puzzle.
You can participate by downloading and running a free program on your computer. This program is hosted by the BOINC framework - the same reliable, secure framework that is used for a large number of other distributed projects. (such as seti@home).
The BOINC framework ensures you can contribute your CPU cycles in a safe manner, within the parameters that you specify.
Eternity2.net is organised by Dave Clark in Auckland, New Zealand, when he isn't working or spending time with his wife and two young children.
The EternityII™ puzzle has a US$2,000,000 prize for the first correct solution. See the official EternityII™ website. If your computer solves the puzzle first, you will win $1,000,000!
Note by Webmaster Yoda
In my opinion, this is not a scientific project but it is driven by "commercial" (though private) interests. Our team does not generally support projects that use BOINC for other than scientific goals, but each member can decide for themselves whether to participate or not.
Be aware that you will have to buy the actual puzzle should you wish to participate.
