.NET GC Internals – the Concurrent Mark phase

Hi and welcome to the third episode of the .NET GC internals! Yesterday is was again 1.5h of talking about the Mark phase, this time in its Concurrent flavour. Most of the time I’ve described the solution and implementation of it to two problems:

  • Problem #1 – how to mark an object while being used? – in non-Concurrent Mark phase MethodTable pointers is used for this. But now, while the application is running and may access this pointer, it is not the best place ever 🙂
  • Problem #2 – how to get a consistent view while references are changing? – even more difficult problem, as the GC tries to discovers what is reachable while references between objects are constantly changed by the application

Enjoy watching the recording on YouTube and if you have any questions, do not hesitate to ask!

As usual, you can get the slides from our goodies page.

And do not forget to join Wednesday, February 10, 7PM CET – this time I’ll cover Plan phase, describing such internal stuff like “plugs”, “gaps”, “brick tables” and more!
