To Compute those 11 Eyes Portal

Trailer Thumbnail 2 Crack CUDA/Nvidia GPU - Released! A new boinc project called trailertcrack has been deployed, it aims at cracking the seed for the Thumbnail 2 of the Trailer video of Minecraft (https://www.youtube.com/watch?v=MmB9b5njVbA), this is currently the last one missing so we can fully reproduce the original trailer within Minecraft in higher quality right in time for the 10th anniversary of this iconic piece of Minecraft history. (we have the majority of the seeds, and this is a working project).



This app is GPU only and you will be rewarded with 3333 credits. Currently, we only support Windows and Linux 64 bits for NVIDIA GPUs (we use cuda).



Happy crunching! Cheers, Neil 30 Sep 2021, 20:04:32 UTC * Discuss Badges Hello crunchers !



We are delighted to announce that 4551 of our participants in the cactus project received a new badge. This badge demonstrates that we appreciate your participation and is a great way to show that.



We wouldn't have been able to do it without you !



Side note We're open to suggestions if you believe that we should do it more often/make higher badge goals.



Cheers,



Neil

We didn't announce the release of OneChunk SSG here even though we've teased it previously, so this post will announce it officially. This is our first CPU project. Tasks will be awarded 2500 credits. Each task is designed to last around the same amount of time. The calculation of rewards is dependent on the current task's duration, power draw of the CPU as well as the previous GPU credit attribution.



This is a long-awaited initiative which is meant to find all seeds with 11 eyes strongholds for Minecraft 1.7/1.8.



Context:



To put it in perspective In Minecraft you will find the option of using a portal to go to the end dimension to take on the final boss known as the dragon of ender. This portal needs 12 tokens (eyes of the ender) to lit up, however some portals have those tokens already inserted from 0 to 12. If 12 are put inside the portal, it lights up and you can go through, however there's an issue with Minecraft 1.8 and below, 12 tokens pre-placed in the portal did not light up the portal automatically so we're trying to find the next best thing 11 tokens/eyes!



Technical Details:



In order to calculate that 11 eye portal there are a lot of things that needs to be computed and the first thing we did was we used a lattice identify all combinations that create a 11 eyes portal then we reverse it to what we call the population seed. Now on Boinc we are trying to identify Stronghold that generates such as the portal room has the seed of a population. Let me clarify the last sentence. We are unable to reverse the process completely, so we utilize the midpoint method. This is where valid numbers are known and we then must simulate forward a layout that is in line with the numbers we previously discovered.

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



In the event that the client requires some additional information, we offer it via an API hosted at ssg.seedfinding.com.



Moving forward - The current tasks (around 1.93M) will take us between 100-200 days. They will produce approximately 200GB of data. It will be processed on the server to provide us with 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!



Neil 13 Aug 2021, 21:14:40 UTC * Discuss OneChunk CPU In Testing (X86_64 and the ARM64) This week is the time when we begin to create tasks and test the OneChunk CPU application in an actual BOINC environment. If the testing tonight and tomorrow proves that these tasks are able to be verified and that our work-gen/task information creation system works as expected, we'll be able to roll it out to our main server [email securedas a Beta Application'. In the last month since my last post about progress, we've experienced yet another round of delays. A large part of this is due to the fact that 'Sia' has not implemented the features we had hoped to use, and certain of our developers have been on the road during the past few weeks.



(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 versions 1.7 and 1.8 simultaneously, and our code has seen significant modifications to the order of filtering and how it works to identify these special seeds and spawns needed for the Super Speedruns / OneChunk challenges.



Below is a screen of my Raspberry Pi 4 (2.025GHz) running four tasks at once. We'll be tweaking the time estimate (known as a config issue), but each individual task will take 4 hours (per core) on an RPi, and for example on a 5800X, it will take approximately 1.5 hours per task per core.



For our BOINCers and those who are interested in running BOINC on a Raspberry Pi 4 (64bit) Please be aware that the latest Debian Repos / Raspbian 64bit OS images are not compatible with BOINC. This may appear as the BOINC client / BOINC manager stating that you don't have "GUI-RPC" password or permissions, and make the process of having the BOINC GUI working more frustrating than it needs to be.
