Yeah, there was a concurrency issue which happened when I cleared the website cache and I didn't see that 3 daemons stopped, I made an auto script so I would get instant feedback and not miss it again. I do apologize to not have noticed it before, this has been fixed and is now mitigated so shouldn't happen ever again.

Hello,
As with all beta applications, some hiccups happened, notably two major ones, credits awarded were not in line with our previous work and multi gpu were not working correctly.
The good news is: We just fixed those 2 issues and now you are able to run the beta workunits as intended.
Current GPU unit will reward 3333 credits (fixed) which is roughly equivalent to our previous jobs for Kaktwoos and in line with the current rewards for onechunk.

As a side note, we are open to discussion about our current rules with credits and we are also making sure to stay in line with the grcpool guidelines.

Cheers,
Neil

So currently in our code we do account for a --device arg that will set the device used by nvidia https://github.com/MrSpike63/TrailerTCrack/blob/master/main.cu#L667.
However somehow your client doesn't pass that argument to the command line. I am trying to reproduce it but so far with 2,3 and 4 gpus no issues. Do you mind sending either the link to the issue on gpugrid or the version of your boinc client?

So the current planning is to filter those in a high core count server for true 12 eyes (should take out 90% of the seeds) and we will split them into 2 groups, spawn chunk ones and not spawn chunk ones. This step might actually be done on boinc also.

Yes I am aware and this got swiftly fixed, however I am waiting for the completion of the project to fix the credits as there is an issue with my current scripts.

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 do already have most of the seeds and this is an active project).

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

Happy crunching !
Cheers, Neil

We just crossed the 50% mark on this project and it took only 50 days !
A big thanks to all of you crunchers, this is huge (about 81GB to be exact)!

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

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 !

Neil
14) Questions and Answers : Web site : Account ownership keys were regenerated (Message 553)
Posted 29 Apr 2021 by Profile neilcaffrei
Post:
In our epic adventure of fixing everything boinc side, we have encountered a small issue, we are not sure how this happened but our account ownership key was corrupted (maybe even never worked before) we looked into that and we generated new ones. This means that if you generated a proof of ownership before (well please reply here with the date of that so I can investigate) then you need to regenerate it. We have still the old public key but our old private key is corrupted. We could still honor old ownership certificate but we would prefer that you update to the new ones. I am so sorry about the inconvenience.
15) Message boards : News : 23 tall blocks cactus found by PDW and edjotron (Message 501)

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.

16) Message boards : News : The Grand BOINCale for Kaktwoos? (Message 492)
Posted 27 Jan 2021 by Profile neilcaffrei
Post:
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.

As you might have noticed, the 3 heights we chose has already been done. But fear not ! We already generated new tasks for y 68-(nice)-70, we will in a few hours pregenerate all the other heights till at least y100 so everyone can have tasks for the next 2 to 3 weeks (according to the current rate).
Cheers,
