Abstract
Major hardware and software vendors are curious about transactional memory (TM),
but are understandably cautious about committing to hardware changes.
Our thesis is that deconstructing transactional memory into separate, interchangeable
components facilitates TM adoption in two ways. First, it aids hardware TM refinement,
allowing vendors to adopt TM earlier, knowing that they can more easily refine aspects later.
Second, it enables the components to be applied to other uses, including reliability, security,
performance, and correctness, providing value even if TM is not widely used. We develop
some evidence for our thesis via experience with LogTM variants and preliminary case
studies of scalable watchpoints and race recording for deterministic replay.
