Portable, Mostly-Concurrent, Mostly-Copying Garbage Collection for Multi-Processors

Hosking, Antony L.


Modern commodity platforms increasingly support thread-level parallelism, which must be exploited by garbage collected applications. We describe the design and implementation of a portable mostly-concurrent mostly-copying garbage collector that exhibits scalable performance on multi-processors. We characterize its performance for heap-intensive workloads on two different multi-processor platforms, showing maximum pause times two orders of magnitude shorter than for fully stop-the-world collection at the cost of some total mutator throughput.
