Xi Yang Australian National University Scalable Garbage Collector On Multi-core Processors Due to the power limit, the trend of developing general purpose processors has been switching from increasing the frequency to increasing the number of cores. To match the roadmap of processors, the software system has to be scalable. The synchronization between cores is one of the most important factor to limit the scalability. In this talk, I will introduce the project we are working on about improving the scalability of garbage collection by avoiding the unnecessary synchronization between parallel collectors.
