Where can I get more details about Julia’s Garbage Collector? I think it uses the “Automatic Reference Counting” method but I’d like to know more details about how it has been implemented and the expected roadmap, what options are going to be added, how does it compares to other alternatives… Also…

“ Automatic Reference Counting ” is an Objective-C/Swift-specific thing. Julia does not do any kind of reference counting. As @yuyichao said, it’s a non-compacting, generational, mark-and-sweep, tracing collector, which at a high level means the following… mark-sweep / tracing: when GC runs, it sta…

Very interesting. To me especial intriguing is thought that I don’t need mutable structures as often as I think I need them, i.e. 90% of time. Does something important changes in workings of Garbage Collector along the way to Julia 1.6? Compiler scheme change very much in 1.6, with great results fo…

No, the GC is pretty much the same. The compiler is somewhat better at seeing that some objects don’t escape the current function call, however, so they can be stack allocated (or even not allocated at all), which means they don’t become garbage in the first place. I think most of the improvement wi…

Comments in gc.c.

No. It’s a non-compacting generational mark-sweep collector. pretty much every part of this is googleable if you want to know more about it.

None. You don’t need to use it directly.
