PhD Project Summary

Under the guidance of Richard Jones I am investigating concurrent Garbage Collection (GC). Commodity computer hardware is starting to require explicit multi-threaded software for performance and new NUMA architectures place a heavy penalty on non-local memory accesses. My research seeks to improve concurrent GC performance including reducing non-local GC memory accesses, improving GC work queue generation and investigating trade offs between mutator and GC synchronisation costs.


My publications are available here.

NEW: An extended version of our ISMM 2010 paper is available here The Locality of Concurrent Write Barriers (extended version)
