When admin finally updates the server version to v1.2.1 it will have the account deletion option available.
You only have an account at the forums though. You may have BOINC installed, but you don't have this project added, so your computer isn't being used. In that case you can uninstall BOINC. And if you didn't even have that installed, absolutely nothing to worry about, you then only have an account here that you don't have to do anything with.

Your Intel built-in GPU does not meet the minimum requirements, so unless you can buy an external GPU that does meet the requirements, you will have to wait for the CPU app that's coming. No ETA on that yet though.

The project admins communicate mostly via their Discord channel. I haven't taken a liking to that yet as it's very confusing for me to try to help one person while 17 others chitter between that in their own discussions. And everyone chimes in, some with completely stupid information.

I wish that admin would take 30 seconds per day to post something about the status of his project via these forums, but alas.


Need to give you moderator powers there too. The bots can only do some much. Without someone to keep things on track, it turns into a general chat except for the locked channels.
I've still got my training wheels on when it comes to Discord, I don't want to be a moderator there. I'm looking into their channel maybe once a week, usually while waiting for a livestream to start on Youtube and as soon as that does I'm off their channel.

No one seems to be getting any work at the moment, with no explanation about why from admin. Or he must've done it on Discord but I'm not 24/7 following that.

This project runs on certain GPUs on Windows and Linux only for now. It does not have an application for Android, iOS or any other handheld platform. So there is nothing you can do about that, other than use a PC.

Seems hit & miss. I did get work earlier today. See that half of that (unstarted) just got aborted by the project. "Cancelled by server". Hmmm, that'll go down well.
9) Message boards : Number crunching : Error while computing for tasks (Message 355)
Posted 23 Jul 2020 by Jord
Post:
All your tasks show "exceeded elapsed time limit" (you can click on Details of your task to see the error message). which would suggest there is either a memory leak or an infinite loop that the project needs to debug. DebugBreak() will cause the Windows Debugger to start up and dump a stack trace of the stuff the application was doing, and report it back to the project. hence the Breakpoint Encountered (0x80000003) message in the stderr.txt

Here's some scheduler contacts for this project just after it came back from switching servers:

So I got 8 tasks, at 9 scheduler contacts. Why? Why can't it download all 8 at the same time?
And are downloads even happening, because I never see any mention of a download. Or upload for that matter.

Difficult to answer with all that maintenance stuff going around.
What do you use to measure GPU load? I use GPU-Z from https://www.techpowerup.com/gpuz/

And after changing the values in app_config.xml, do use BOINC Manager->Options->Read config files, or exit BOINC and restart it.
<gpu_usage> set to 1 means 1 task, 0.5 means 2 tasks, 0.33 means 3 tasks, 0.25 means 4 tasks.
<cpu_usage> means how much CPU you want all the apps specified to use at maximum. Luckily the kaktwoos app isn't CPU heavy so you can leave that at 0.4
But your gpu_usage of 0.8 is something BOINC sees as 1 task.

So do set for two tasks
<app_config>
<app>
<name>kaktwoos</name>
<max_concurrent>2</max_concurrent>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.4</cpu_usage>
</gpu_versions>
</app>
</app_config>

Or for three tasks

<app_config>
<app>
<name>kaktwoos</name>
<max_concurrent>3</max_concurrent>
<gpu_versions>
<gpu_usage>.33</gpu_usage>
<cpu_usage>.4</cpu_usage>
</gpu_versions>
</app>
</app_config>

Or for four tasks

<app_config>
<app>
<name>kaktwoos</name>
<max_concurrent>4</max_concurrent>
<gpu_versions>
<gpu_usage>.25</gpu_usage>
<cpu_usage>.4</cpu_usage>
</gpu_versions>
</app>
</app_config>

The <max_concurrent> changes per amount of tasks you want to run on the GPU as well. If you quickly want to return to running just 1 task, set <max_concurrent> back to 1.

One thing I forgot. Set BOINC to use one less CPU core than all via the Use at most N% of the CPUs set to 99%. It's an integer, so 100% means all, 99% means all minus 1.
This one core will then run background stuff like Windows, but is also used by the GPU app. Because if you load all CPU cores with tasks and then try to run a GPU app as well, it will also try to run on a core... which there aren't any one anymore. So just instruct BOINC to use one less core and that'll fix itself.

Also, I just tested the setup myself and seen that the <cpu_usage>0.9</cpu_usage> was too high, so screwed it back down to 0.4 in my example above.
Please follow suit. And just play with the values.

When running one task, it takes 19m 45s.
Two is 35m 26s and 36m 01s. So it does help.

You'll have to find the sweet spot yourself. I don't know what it is. You won't be able to load 10 tasks at a time because that will just be overkill. But play with 2, 3 at a time. 2 at a time on my RX 5700 XT gives 99% GPU load.

You can use an app_config.xml file in the BOINC/projects/minecraftathome.com folder with the following in it:

<app_config>
<app>
<name>kaktwoos</name>
<max_concurrent>2</max_concurrent>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.4</cpu_usage>
</gpu_versions>
</app>
</app_config>
This loads two tasks at once.

Make the file with Notepad or Notepad++ and make sure when you save it that you save it in ANSI encoding format and with the XML extension.
Play around with the values. For more information on this, see https://boinc.berkeley.edu/wiki/Client_configuration#Project-level_configuration

With integrated GPU you mean an Intel GPU? Just go to https://minecraftathome.com/minecrafthome/prefs.php?subset=project (that's the project preferences from your account), edit them, uncheck "Use Intel GPU" and save the changes. That way the next time BOINC asks for work, it won't get any anymore for the Intel GPU.

I apologize for the server crash, as we had a huge increase of users due to the Panorama seed being found, causing various scheduling issues and compounded by tasks being cleaned up improperly by the server.
They're still not being deleted. I still have mention of all tasks since I started this project.
