The GC book by Jones is the place to start to understand GC in general. He also has a new "GC Handbook," but I haven't looked through it yet to see how well it covers modern parallel and concurrent collectors, particularly for NUMA machines. Having spent a large portion of the last five years working on a parallel concurrent collector that scales to 48-AMD and 64-Intel cores, I can say the game's totally different on NUMA architectures. Unfortunately, not much has been written yet on it (I have an MSPC paper; the Intel folks have a paper on Pillar that was at ISMM; that's about it). Feel free to ping me directly if you get to advanced material and need more pointers. Many of the systems have not yet been published, as it's shockingly difficult to publish on modern GC implementations these days.
