Posted · Why is Cura not using all my CPU cores?

I have the latest Mac Pro and designing on it is amazing. But what i dont understand is that most of my designers programs are not using the full capacity of my cpu. Even Cura is not a multicore program. Why is that? I mean, it is a designers program and using the full maximum of all cores could only benefit the workflow. But when i slice my projects it takes forever before it is done. Sometimes Cure even hangs.

 

So why is Cura not made for using multicores?

    Posted · Why is Cura not using all my CPU cores?

    There are multiple reasons. First off is the compiler for OSX that is just more outdated than those for Linux and Windows, making it much harder to get certain multi threading options available. We're looking into porting it, but that is why the osx version of Cura has less multi threading options.

    Another (more fundamental) problem is that large parts of the slicing process are simply serial; The results of one layer depend on the results of the previous layer. As such, you can't calculate them in parallel.
