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.

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.

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.

Oh good.I don't know why some Linux distros sometimes make certain folders read only by default. If that happens then the above command gives you back full read and write authority.
