Abstract:

Transactional memory (TM) is a promising new tool for shared memory application development. Unlike mutual exclusion locks, TM allows atomic sections to execute concurrently, potentially resulting in improved performance. Commercial releases of hardware TM (HTM) brings this functionality to the mainstream.

However, these HTM implementations are built on top of existing hardware, and provide TM functionality with minimal hardware changes. As a result, there are significant gaps in performance compared to research prototypes that can work from a clean slate. In this thesis, I propose to several ideas that keep with this design philosophy, but still close this gap.
