This is the app_config.xml file I use when I just want to limit the number of tasks running by a project:

<app_config>
<project_max_concurrent>5</project_max_concurrent>
</app_config>

Change the number as needed but using a zero instead of a 5 in this example would let the project use every cpu core, this way I can run 5 tasks from this project, 3 tasks from that project etc until I run out of cpu cores on the pc.

That is the same Code I used in my app_config.xml file, but the project wasn't just using the Cores I defined. Instead it started as much Tasks as my CPU has Cores. And the PC was unusable instantly after they started.

That's not a Project, that's a mess.

Did you remember to click to 'read config files' under Options in the Boinc Manager? Whenever you make a change in a config file it's the easy way to get Boinc to do what we want it to do.

That is not relevant. The exe for a single task uses more than 1 CPU thread.

So you are saying they are already multi-threaded?

Are you running the Linux tasks yet? I was wondering if they were better/easier to setup. I think I've done everything I was supposed to do but I don't have a single valid task so far on 2 Windows pc's.

I am saying they are using more CPU than they should. BOINC says 1 CPU but it uses more.

No, I ran my 100 hours for WUProp. This project is useless.

That is not relevant. The exe for a single task uses more than 1 CPU thread.

Haven't tried wine or Windows in VM yet. I haven't seen any tasks using more than one thread on Linux. Yesterday, tasks seemed to use virtually no CPU at all. Today, each task is using 100% of a CPU.

They seem to work ok now. I ran a couple as well.

Does anybody know the path of the contribute folder under Linux? I can't find it...

It creates a Slots folder but no Contribute folder anywhere that I can find in Linux. Every WU has failed.

Axion runs with Linux Mint 22.3 and creates empty folder /boinc/Axiom/contribute/

Ok found it, thanks! That folder was locked on my system so if anybody runs into the same problem here is how to gain full access to it: sudo chmod 777 -c -R /var/lib/boinc/Axiom. Otherwise you can't copy any data into that folder.

I use Linux Mint but what does "777" mean? Is that where your username goes?

Each 7 is a read + write + execute for the owner, group and others. No username is needed

I didn't have add anything to the folder in Ubuntu or Windows.
