Minecraft@home - OneChunk launch and onwards
- Détails
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 which 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 the client needs a bit more data we provide it from an API hosted 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.
You can download the current results here: https://files.seedfinding.com, those are the raw results (seeds, coordinates) and will be further processed later on but they are already 11 eyes strongholds.
Happy crunching !

Minecraft@home - OneChunk CPU In Testing (X86_64 & ARM64)
- Détails
(See; https://minecraftathome.com/minecrafthome/forum_thread.php?id=102 )
On the bright side, we shall now be checking seeds for 11-Eye dungeons in version 1.7 and 1.8 at the same time, and our code has had some significant changes for the order of 'filtering' and how it works to find these special seeds and spawns required for the Super Speedruns / OneChunk challenges.
Shown below is a screenshot of my Raspberry Pi 4 (2.025GHz) running 4 tasks concurrently. We will be tweaking the time estimate (known config issue), but each individual task will take 4 hours (per core) on an RPi, and for example on a 5800X it takes about 1.5 hours per task per core.

For our BOINCers and those interested in running on a Raspberry Pi 4 (64bit), please note that the latest Debian Repos / Raspbian 64bit OS images have an issue with BOINC. This may appear as the BOINC client / BOINC manager saying you do not have a "GUI-RPC" permissions or password, and make the process of having the BOINC GUI working more frustrating than it should be. There's a few guides and other forum posts on this issue, but I shall probably make a quick step by step guide to ensure BOINC is operating properly *if* your 64bit ARM distribution wants to not play nice
