A concurrent, generational garbage collector for a multithreaded implementation of ML

International audienceThis paper presents the design and implementation of a "quasi real-time" garbage collector for Concurrent Caml Light, an implementation of ML with threads. This two-generation system combines a fast, asynchronous copying collector on the young generation with a non-disruptive concurrent marking collector on the old generation. This design crucially relies on the ML compile-time distinction between mutable and immutable objects
