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.

I thought I had bad luck when the wiki got deleted, but the fact that the tallest cactus seed record was broken had me think that it wasn't about my luck!

If anyone's interested in the changes we're making to kaktwoos (the optimizations), here's the github and code changes that you can hopefully try to understand

https://github.com/minecrafthome/kaktwoos-cl/pull/23 (Application code)

https://github.com/minecrafthome/minecrafthome/pull/69 (BOINC configuration code)

https://minecraftathome.com/minecrafthome/forum_thread.php?id=88 Thread on these changes, and how you can help us (if you'd like!)

Update: Have received various performance improvement reports, and some older graphics cards receiving penalties. We have also fixed a backend issue regarding Intel-Linux v2.11 application, causing some clients to not be able to work on tasks on that platform.

In another thread I compiled a report on which GPUs may need to use the older kernel, and so I must ensure I match those up with their specific chip/OpenCL ID for Nvidia now. For reference, my Vega 56 is "GFX900", which can be input or used by the kaktwoos-cl-amd to load a different kernel

Just a quick announcement:

By this weekend, we shall have all Y=65 tasks finished, and Y=66 tasks (100-150K) launched.
Sadly, there are *no new tall cacti* to report. No 24s, not even for Superflat or preliminary verification

I just try to figure out which Minecraft to install on the W10 box https://minecraftathome.com/minecrafthome/results.php?hostid=12228 for my 10 year old boy and to be able to see the tallest cactus this project will ever discover at the same time. And no, I never have played Minecraft myself.

Update!
We've found a 25 tall Superflat Cactus, which I believe means we broke our (Superflat) record after over 6 months of waiting!

To generate, please open Minecraft Java 1.14.4, choose Superflat preset -> Desert (14*sand instead of 8*sand) and input seeds:

Thanks to Vanos0512 (UID:869) and Greger (UID:12272) for calculating this record-breaker.
