Hi, Here is my paper for icmc 2009: http://users.notam02.no/~kjetism/rollendurchmesserzeitsammler/gc_icmc2009.pdf
It documents the garbage collector used in snd-rt, plus benchmarks, extensions, and discussions about realtime music programming. I wanted to add some illustrations, larger fonts for the pseudo code, more white-space in the item lists, more references, more information about previous work, more detailed explanations and discussions, etc., but it couldn't be included because of limited space. I hope it should be quite understandable and readable anyway. Abstract: " Garbage-producing and efficient programming languages such as Haskell, Lisp or ML have traditionally not been used for generating individual samples in realtime. The reason is a lack of garbage collector fast and predictably enough to make these languages viable alternatives to C and C++ for high performing audio DSP. This paper shows how conservative garbage collectors can be used efficiently for realtime audio signal processing. Two new garbage collectors are described. The first collector can easily replace garbage collectors in many existing programming languages and has successfully been used for the Stalin Scheme implementation. The second garbage collector has a higher memory overhead and requires a simple write barrier, but does not restrain the amount of memory. Both collectors find garbage by running a parallel mark-and-sweep on snapshots. The snapshot buffers are either copied to between soundcard interrupts or filled up by write barriers. To ensure predictability, worst-case is simulated about once a second, and all running garbage collectors are synchronized to avoid more than one garbage collector to block audio simultaneously.
