Live programming, originally introduced by Smalltalk and Lisp, and now gaining popularity in contemporary systems such as Swift, requires on-the-fly support for object schema migration, such that the layout of objects may be changed while the program ...

Now that the use of garbage collection in languages like Java is becoming widely accepted due to the safety and software engineering benefits it provides, there is significant interest in applying garbage collection to hard real-time systems. Past ...

We describe the Collie collector, a fully concurrent compacting collector that uses transactional memory techniques to achieve wait-free compaction. The collector uses compaction as the primary means of reclaiming unused memory, and performs "individual ...

In order for a garbage collector to concurrently move an object while an application mutator thread accesses it, either read or write barriers are necessary. A read barrier places certain invariants on loaded values that allow the garbage collector and ...

C4, the Continuously Concurrent Compacting Collector, an updated generational form of the Pauseless GC Algorithm [7], is introduced and described, along with details of its implementation on modern X86 hardware. It uses a read barrier to support concur- ...

We present a virtualisation and method specialisation framework for Java that facilitates efficient, dynamic modification of the behaviour of object accesses at run time. The technique works by virtualising all method calls and field accesses associated ...

Read barriers synchronize compacting garbage collection and application processing in a simple yet elegant way. Unfortunately, read barrier checks are expensive to implement in software, and even with hardware support, the clustering of read barrier ...
