Badges
Hello crunchers !

We are happy to announce that we rewarded 4551 of you with a brand new badge for your participation in the cactus projects, we are truly grateful of your participation and we though that having such badge would be a good way to show it.

We couldn't have done it without you !

On a side note, we are open to suggestion if you feel like we should do that more often/make more badge goals.

Cheers,

Neil

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 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 !

OneChunk CPU In Testing (X86_64 & ARM64)
This week marks the period where we finally begin creating tasks and testing the OneChunk CPU application in an actual BOINC environment. Once tonight and tomorrow's testing shows that we can validate these tasks, and that our work-gen / task data creation system is working as expected we shall be able to roll this out to our main [email protected] server as a 'Beta App'. Over the past month since my last progress post we've had yet another set of delays. Some of this is because 'Sia' has not implemented the features we were hoping to use, and also some of our developers have been travelling in 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 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

Kaktwoos version 2.13 released + reminders for Nvidia Linux OpenCL packages
We've released the latest version of Kaktwoos-cl, which is now 2.13!

In this update, we've added further checks for GPU model detection and printout for what GPU and its 'name' a given Kaktwoos-cl task is on. Please note that we highly suggest you run sudo apt-get install nvidia-opencl-dev if you are on Ubuntu or Debian (or a corresponding package + command on your distro) in order to install the missing OpenCL headers and allow Kaktwoos-cl to run. We would appreciate that all BOINC users thinking or currently running Nvidia GPUs on Linux to verify that BOINC tasks are not reporting computation errors accidentally, and leaving them running 'carelessly'. We have not truly resolved the very rare 'stuck at 100% / Infinite Task' post-crash issue, and we recommend for those tasks to be aborted manually if you encounter one at >99% for more than 10 minutes on a new GPU.

Changes:
Nvidia GPUs will use one of two kernels depending on their age and model. For example, any RTX or 16xx (Turing) GPU shall continue to use optimizations introduced in Kaktwoos v2.10. Older or weaker GPU models shall use the previous kernel, which means we should see a 5% boost to any GPUs reported to have a regression, as some of you may reported on our BOINC threads.

AMD RDNA1/2 GPUs are now detected and matched to use another set of optimizations, increasing their speed to their original (pre 2.10) or further increasing it. Due to architectural differences, changes made that improved GCN (ie RX 480, Vega 56) performance by 25-40% reduced RDNA 1/2 performance by up to 2X, which is now mitigated.

All task outputs will include the seed range searched as well (s: and e: parameters) for general interest and debugging potential. Otherwise, there is not much left I (Hy) feel there is to code for Kaktwoos-cl, and CPU projects are now more of a focus for [email protected] than before, as you may have seen with our OneChunk pre-announcement.

OneChunk CPU Pre-Announcement (X86_64 & ARM64)
Over on the [email protected] discord, Boysanic ("Boincboi"), Matt (Stronghold simulation coding), other developers and I have been discussing and planning a rollout of our first CPU application. This OneChunk project is "a BOINC project in the works. Our goal is to find all world seeds w/ at least an 11 eye portal in MC Java 1.7.10". So, if this all works out, "you'll finally be able to say you've found an 11 eye portal by yourself!"

Essentially, we are combining parts of the "SSG" (Seed-Speedrun) and 11-eye portal seed-filtering programs together to go through a large dataset. This input file is 9GB in size, but we plan to split it up into many small manageable tasks to be distributed through BOINC, which is where you come in! Going through a 320kb sample input takes a 4.8GHz Ryzen 5800 (the fastest single-core CPU) around 2 minutes, simulating and checking over 5,220 worldseeds a second. A 2GHz Raspberry Pi 4, with 64bit Raspbian manages to compute 1,370 worldseeds a second, making it around 3.8x slower but much more efficient. (45W vs 5W)

Thanks to work by other developers, I have tested and confirmed that both x86_64 ("64bit Windows and Linux") and ARM64 (64bit Linux ARMv8) configurations will work. The OneChunk 'Filter9000' BOINC application is single-threaded, but will likely have multiple tasks running concurrently on your computer to best utilize its resources and scale to your unique hardware configurations. For 'PC' requirements, we suggest Ubuntu 18.04/20.04 64bit or Windows 7 / 10 64bit, running on an CPU such as an AMD FX or Intel 1st Gen Core i5/i7 CPU or newer.

If anyone has a Raspberry Pi 3(B/B+) or 4, we would like to invite you to install the latest 64bit Raspbian on a spare SDcard in preparation. We also expect Nvidia Jetson Nano/TX1/Xavier devices with Ubuntu 18.04 64bit or newer to successfully run our Arm64 tasks, once we configure our BOINC server to provide and schedule tasks for this platform.

Please follow instructions on the Raspberry Pi website, but we suggest that more experienced Pi users join us for this experiment! OS image below:

23 tall blocks cactus found by PDW and edjotron
We've discovered the first naturally generated 23-Tall Cactus! Thanks to PDW and Edjotron, we can now confirm that the tallest is 23 blocks. To see this cacti in its natural habitat, right by a Mesa, please input the seed

184693195438010998
on 1.14 and use
/tp 16274576 64 10230656 
to teleport to it, right next to the badlands!

As some of you may have seen on the BOINC Forums News updates, developers Balint, Hy and Boincboi have confirmed stability of our new optimization updates. These optimizations to Kaktwoos will allow many models of AMD GPUs to get between 30 and 50% performance, like the RX 480 and RX Vega series. Additionally, some RTX 2000 series graphics cards may see small boost in speed, of 5-10%, while a few (such as an RTX 2060) may see up to 75% more performance!

This means almost all of you can compute cacti much faster, as we launch the next round of Kaktwoos at y=65 shortly.

The Grand BOINCale for Kaktwoos?
We apologize yet again for the lack of work over the past month and a half, since all of you had last BOINC'd to solve Minecraft’s tallest cactus mystery. Now, after improving Kaktwoos’ ease of use for our developers we are ready for one last, hopefully long round of cactus stacking and chunk smashing with our fellow cacti enthusiasts. Thanks to some changes behind the scenes, our developers no longer have to painfully modify many configuration files and verify multiple server adjustments (as mentioned in our previous post). At most now they will only have to change two numbers and send work out, as all of the preliminary seeds have been pre-loaded for BOINC to work off of! So, how much work do we expect to generate over the next few days?

Well for starters, an average run of ‘Kaktwoos’ per block layer (y-level) creates 120,000 tasks at a minimum, and each task takes a midrange gaming GPU at least an hour to complete. We have at least 10 layers planned to be checked for 23 and 24-block tall cacti, making this one of our most comprehensive searches yet. Even with 1000 users computing away 24/7, we can imagine this work, and reviewing all the data from it will take at least *60* days. This doesn’t even include that the seeds we are working on are only a fraction of the potential cacti to be stacked, though are the most likely to successfully merge into Tall Cacti at these unusual heights.

So, how high up in a desert do you think we can find tall cacti? Will ‘Superflat’ presets be the final destination for outrageously tall cacti searches? Join us now at [email protected] to find out, and bring back immense compute power to our BOINC network! We recommend anyone with a Windows 7/10 64bit and Ubuntu 18.04 or newer OS to join, and especially those with an AMD RX 460, GTX 750ti or newer/faster. Intel Graphics are supported as well, and multiple GPU systems are in high demand and very capable to assist us. If you’re in the Northern Hemisphere feeling cold and isolated this winter, why not BOINC with us and chat in our Discord server https://discord.gg/xArErFf , or pay a visit to our messaging board?

If you have already begun the penultimate search for ‘stacctus’ with us already, try to find your own tall cacti under ‘Your Tasks’ in the BOINC client’s ‘Advanced View’, then by clicking on the task number inside your browser. Inside those logs maybe there’s a chance you’ll find a 22 or taller ‘natural’ cactus of your own, that you can build by and share with us. We will be posting updates often to announce any interesting findings from your hard work, so stay tuned in the upcoming weeks for more.

From sandy valleys, up to sand dune peaks. Kaktoos rises to the challenge!
After a somewhat long hiatus, Kaktoos is coming back for another round in the ring, and this time at higher and higher heights. Many of us who contribute to the project ([email protected]) got a little busy with school/work after the Pack project concluded, so I apologize on everyone’s behalf for the silence and uncertainty as of late.

As for where we left off, the y=62 search wasn’t as fruitful as we would have liked. No taller cacti had been found at this height than were found at the slightly higher height, y=63.

With the way things usually go, we would need to create an entirely new version of the program in order to run kaktoos for different heights. We started on y=63 for the original version of the program, and then changed this to y=62 for the second run of the program.

This time around, we’ve flipped the script, and different heights can now easily be run at the same time or in series, with 0 program changes. Effectively we’ll be able to get the final answers we’re looking for from the kaktoos project much easier and without as much “red tape” as there usually is with program changes due to security reasons.

What does this mean for you?

This means more kaktoos, more often, and with less breaks between runs for the foreseeable future.

There’s some limits to how many heights we can attempt since there comes a point where you simply will not find any cactus, however, we have a fair range to work with now with these new changes in play.

What now?

We’ll be launching a run of kaktoos very shortly. We’ve been testing this in beta with a height value of 64 for a short period of time to make sure that things are running as smoothly as we would like, but we’re happy to announce that we’re ready to go!

Some have offered far more support than we ever expected during this beta, which definitely surprised us! We’re grateful for everyone’s enthusiasm, even if it’s to our own disadvantage to have this run done so quickly.

For the curious, this new run will encapsulate heights of 65, 66, and 67.

That said, happy crunching! Kaktoos runs will begin soon outside of beta. Thank you all for the support and understanding over the last couple months as we work through things.

We have found the SEED of Minecraft's title-screen background PANORAMA!
Everyone should be familiar with this world. It's the one that always appeared on Minecraft's main-menu (title-screen), blurred and slowly rotating.
It first appeared in 2011 for Minecraft Beta 1.8 and remained for many years, it was only recently replaced in 1.13 each subsequent version.



The seed was found on 18th of July 2020 at around 5:45 AM UTC.

Version: Beta 1.7.3
Coordinates: X=61.48~, Y=75, Z=-68.73~
Seed: 2151901553968352745 OR 8091867987493326313 (both work)



Why two seeds? There are actually 2^16 (=65536) seeds that will all generate the same world. Older versions of Minecraft used only 48 of the bits of the seed. Here's the formula for getting all of them, as explained by Earthcomputer:
25357015387625 + 2^48k, 0 <= k < 2^16; (k is an integer)
The two seeds mentioned are the only "valid" seeds, in the sense that they can be naturally generated by Minecraft (due to Java's random function implementation).
There is not any word/string of characters that will produce this seed, it was generated randomly.
This has nothing to do with "shadow seeds", they are not present in these versions.
What can change is placement of trees and fauna as that depends on the order chunks are generated; otherwise, there are no differences between the two seeds.

Earthcomputer, Cortex, Neil - wrote the biome and terrain checking code
DutChen18 - made multiple tools/mods to help with the recreation and gathering data for the seed checking
MC PseudoGravity - reversed the tallgrass colors and found the biome values in the panorama
Philipp_DE - hosted the recreation server and screenshot bot
Tomlacko - started the project, found the coordinates, produced the panorama viewer with recreation overlay
...many other people helped in other ways (such as building the recreation block-by-block) listed here.

Onwards to new and great (actually, lesser) heights (of cacti)
The first round of Kaktwoos processing is nearing its completion. A small number of hosts caused many errors with faulty hardware or software configurations which caused the failure of a handful of workunits. Due to these failures; several thousand new tasks have now been submitted to allow any previously failed workunits an additional chance to succeed.

All historically submitted data is currently under re-evaluation as a subset of these completed tasks has outputs which don't appear to be nominal. The re-validation of tasks will reach completion shortly, and soon a follow-up will be posted detailing the tallest cactus found during this round of Kaktwoos processing.

The Kaktwoos (kak-two-s) project was initiated by computing a small set of tall 'candidate cacti' using the single-chunk cacti stacking application Kaktoos (kak-tus). The initial cactus seed search assumed stacking began at an elevation of y=63 blocks from bedrock which is the basis of assumption for the Kaktwoos multi-chunk cacti scanning work. You have likely volunteered resources towards this effort over the past few weeks.

Now, onto the exciting news: the Kaktoos application (note the missing 'w') shall be launching on BOINC.

This application will exist to scan for individual chunk seeds which produce tall cacti (7 blocks minimum) with generation elevation of y=62. Using a lower elevation parameter for Kaktoos will hopefully allow us to discover additional naturally-generated 22+ block tall cacti with Kaktwoos.

For those wondering, the next set of tasks will produce many more resultant 'candidate' cactus seeds than the previous y=63 run. We expect 120 million generated seeds despite the required minimum height of 7 blocks we chose to reduce output drastically. This dataset will be used for quad-chunk stacking (Kaktfours anyone?) and is much more challenging to manage due to the lower probability of finding 22+ block tall cacti and increased development overhead. We could theoretically find much taller cacti with this method, with a caveat of requiring significantly more processing power. Don't worry though; there are other projects brewing which will take priority. If you are a 'stacktus' superfan or a member of the 'big cactus community', you also needn't worry; there may be even more permutations of Kaktoos and Kaktwoos inputs to try which should keep us all busy along the way.

Finally, and for reference, the tallest known cactus found by [email protected] (in Minecraft: Java Edition v1.14.4) is 22 blocks, and 24 blocks tall if using a superflat world with the desert preset. We distinguish these heights as we consider "cactus naturalis" (cactus of normal generation) cacti to be the true tall cacti, as opposed to "cactus fma vi" (cactus of superflat generation).

Server outage resolved and supporting our infrastructure
Between 23:54 UTC yesterday (2020-07-20) and 15:35 UTC today, we suffered from a catastrophic SQL failure which forced us to restore from backup.

There may be some credit issues where the system granted more or fewer credits than you expect for work done during this time.
I can't apologize enough. If our BOINC deployment was architected for scale rather than for low cost, we could've avoided this.

There are several enhancements to our infrastructure and upgrades we'd like to make, such as migrating services to Kubernetes and potentially using a managed SQL service.

That was fast
The origin of the panorama image used in the Minecraft main menu from beta version 1.8.1, released in September 2011, has remained a mystery until now.

In less than 24 hours after launching the panorama application; a volunteer host for [email protected], in a sheer stroke of luck, found the world seed, 25357015387625.
This was approximately 93 days of processing time at a total of 54.5 exaFLOPs compressed into the last 24 hours.

The specific host which located the seed belongs to the user vanos0512.
Thank you to the 137 users who contributed 181 hosts with 231 GPUs over the last 24 hours. You all accomplished this.



Here are the details if you want to generate this world for yourself:
Minecraft version: Beta 1.7
Either of these two valid world seeds: 2151901553968352745 or 8091867987493326313

Enjoy the scenery
[email protected] is now over one month old! To celebrate this milestone, I present a new research focus; the panorama project.

If you were here during beta-testing, you might have received a very early version of panorama tasks, and the eagle-eyed among you may have seen the application details on the server status page.

The panorama app is a CUDA-only app for Linux and Windows with an Nvidia driver version of 418.96 or higher.

This project attempts to find the world seed of the iconic panorama image which appeared in the background of the main menu of Minecraft between 2011 and 2018. The first phase of this project will only last a few days, and we shall update you with their progress in the coming weeks.



Right now, the application is quite substantial. Unlike the OpenCL applications for the Kaktwoos project, if you allow BOINC to run tasks always; you may experience some stuttering or lag in your desktop environment while running these tasks. These tasks do not have checkpointing support, but run in around 1 hour on an average host to mitigate the majority of lost cycles.

As always, you can change which projects of which you decide to participate in your user preferences.

Let us know if you have any questions, and as always join the discussion over on the Discord server.

Kaktwoos 2.03 and Badges!
You may have seen many workunits just disappear from existence today.



Worry not! We realised there were far too many workunits scanning duplicate seeds, so we've scaled back the original workunits to the correct seed ranges (no in-progress results were touched, so none of you should have lost any credit).

We have located some promising seed candidates which were missed from processing and can be used as an input to this job, so they are currently set as the highest priority.

Also, we now have badges! If you view the forums, any comments in threads, or on the leaderboards; you will see the new badges.
We're open to suggestions for future badges, so please leave us some comments on this thread.

Profile creation and OpenCL vendor pinning
In the last news post, I advised everyone to create a profile in order to be eligible for 'user of the day' selection.
Unfortunately, there was an issue with the ReCaptcha implementation which prevented this. This issue is now resolved.

Now, you are able to create a profile here.

Also, good news for hosts with OpenCL capable hardware from more than one vendor (e.g. an Intel iGPU and an Nvidia GPU)
The latest update to the kaktwoos app should ensure the tasks run on the correct device.
If you are a user with a multi-vendor host, please keep an eye on your results and let us know if you're having any issues.

As always, please get involved with the conversation in the message boards, and join the Discord!

MultiGPU, checkpointing, and another record breaking cactus (22 blocks tall)
Finally, support for multiple GPUs and checkpointing has landed.

• If you have multiple GPUs, the research apps will now make use of all available GPUs.
• We now support Intel GPUs.
• If work is suspended, or your machine is powered off, checkpoints will now ensure work does not start from the beginning.
• You will also notice work estimates are far more accurate.
• You do not need to take any actions to enable these features.
• We are also taking steps to increase the priority of additional results added to workunits after computation errors. This in order to speed up validation of incomplete workunits.

Thank you to Hypprs, nicoboss, DutChen18, BalintCsala, and anyone else who was involved in testing and updating the app.

For the third time in 1 week, [email protected] has broken the tallest cactus height record in normal terrain generation.

BOINC Project
Many new members have joined from SalC1's announcement and the listing of our project on the BOINC site. We welcome and hope to see all members stick around to see the community's contributions, development, and achievements.

[email protected] is a research project to locate seeds, features, the unknown, and the unseen in the block game, Minecraft.

Minecraft is currently the best-selling video game of all time. Although we have no affiliation with Microsoft, Mojang, or the development of Minecraft itself; this project was born out of necessity. Many members of the community have the desire to push the game, which keeps on giving, to its limits.

The listing of [email protected] allows users to join the project more efficiently. Volunteer compute resources are essential to the success of our research, as some elements require high volumes of computing power in order to retrieve results.

As many may have seen in the latest batch of workunits, we have had a series of errors and issues. We believe these to be mostly ironed out.
BOINC is a learning experience for us all. Grid computing technology is very new to us, so there has, of course, been some teething issues.
We ask the community to bear with us as we perfect our development workflows and move to release more projects and exciting news in the coming weeks.

We are live
The beta period has ended! We are happy with the progress so far, thanks to all who contributed during this phase of the project.

We have now pushed over 1.2 million work units for processing as part of the cactus finding project.
This is following the success of locating world seeds for cactuses up to 21 blocks tall, 2 blocks higher than the existing record.

You may notice a new application, panorama; this is attempting to locate the world seed which was used for the panorama screenshot used in the Minecraft main menu.

There are plenty more applications and work units to come. Thank you all once again for taking part in this adventure.

Beta testing now live
The [email protected] server is now open for beta-testing.

Kaktwoos is the first application in test with several thousand work units available for processing.
Currently, this application only supports Windows 64-bit clients with an Nvidia GPU, this will be expanded to cover the majority of other platforms soon.

Kaktwoos uses chunk seed generation to find cactus stacks of 20 blocks or higher by locating neighbouring chunk seeds which overlap with the input chunk seed.
Cactus stacks generate when two overlapping chunk seeds generate a cactus on the same x, y coordinate.
The input seeds for Kaktwoos were generated by scanning all 281.7 trillion possible chunk seeds for cactuses of 10 blocks or higher. This yielded 42,497 seeds which were algorithmically reduced to a smaller sample (used as the input for Kaktwoos) by scoring each for the likeliness to collide with another cactus.

During beta testing, any issued credits will be cleared as the beta period ends, this is to ensure fairness once we are out of beta-testing.
Any work unit time estimates are inaccurate as we have not specified the number of floating-point operations required for work unit runtime during this stage of testing.

Computation errors during this stage are expected and should be ignored. We kindly ask you to leave your clients running for as long as possible whenever idle to allow us to take full advantage of this beta test.
