OneChunk launch and onwards

Hello everyone,

We didn't announce the launch of OneChunk SSG here even though we teased it already so this post is announcing it officially. This is our first CPU project and 2500 credits will be awarded by tasks since all have been designed to last approximately the same time. The calculation for the reward is based on the current runtime of a task, power draw of a CPU and our past GPU credits attribution.

This is a long-awaited project that is meant to find all seeds with 11 eyes stronghold for Minecraft 1.7/1.8.

Context :

To put it in context in Minecraft, you have a portal that allows you to go to the end dimension to beat the final boss called the ender dragon. This portal needs 12 tokens (eyes of ender) to lit up, fortunately some portal have those tokens already inserted from 0 to 12. If 12 are put inside the portal lit up and you can go through, however there is a catch in Minecraft 1.8 and below, 12 pre placed tokens didn't lit up the portal automatically so we are finding the next best thing 11 tokens/eyes ones!

Technical Details :

To compute those 11 eyes portal, a lot of stuff needs to be computed, the first thing we did is we used a lattice to find all combination that makes a 11 eyes portal then we reverse it to what we call a population seed and now on Boinc we are trying to find Stronghold that generates such as the portal room have that population seed. If you didn't get that last part, let me make it a bit clearer, basically we can not reverse fully the process so we use the midpoint strategy where we know valid numbers that were reversed and then we need to simulate forward a layout such as we match the numbers we found previously.

You can find our project here: https://github.com/minecrafthome/OneChunk and the Pull Request with the binaries : https://github.com/minecrafthome/minecrafthome/pull/77

As client needs a bit more data we provide all the data from an API at ssg.seedfinding.com.

Onward :
The current tasks (around 1.9M) should last us about 100-200 days and will yield about 200GB of data that will then be processed directly on the server to give us the best seed.

Happy crunching !

Neil
