A fast analysis for thread-local garbage collection with dynamic class loading
Richard Jones and Andy King
In Fifth IEEE International Workshop on Source Code Analysis and Manipulation, pages 182-196, Budapest, September 2005. IEEE Computer Society.Abstract
Long-running, heavily multi-threaded, Java server applications make stringent demands of garbage collector (GC) performance. Synchronisation of all application threads before garbage collection is a significant bottleneck for JVMs that use native threads.
We present a new static analysis and a novel GC framework designed to address this issue by allowing independent collection of thread-local heaps. In contrast to previous work, our solution safely classifies objects even in the presence of dynamic class loading, requires neither write-barriers that may do unbounded work, nor synchronisation, nor locks during thread-local collections; our analysis is sufficiently fast to permit its integration into a high-performance, production-quality virtual machine.
This paper is a shorter version of our
technical report.
