- This paper is significant because it contains the first demonstration of how transactional memory (in hardware or software) can support concurrent garbage collection. Our work leverages Intel’s Restricted Transactional Memory to increase concurrent object copying speed in a high performance Java virtual machine by up to 2x over the widely adopted DaCapo. Most surprisingly, and crucially for broader adoption, our novel software transactional memory mechanism achieves the same performance gains on systems without hardware support. The compiler components of our system have been adopted by the Legato system.
