Abstract
Transactional programming promises to substantially simplify the development and maintenance of correct, scalable, and efficient concurrent programs. Designs for supporting transactional programming using transactional memory implemented in hardware, software, and a mixture of the two have emerged recently. However, various features and capabilities that would be desirable for debugging programs executed using transactional memory are absent from conventional debuggers. Because transactional memory implementations provide the “illusion” of multiple memory locations changing value atomically, while in fact they do not, there can be significant challenges involved with integrating debuggers with such programs to provide the user with a coherent view of program execution. We describe use of transactional memory access tracking mechanism for implementations of watchpoints on memory locations that correspond to transactional variables.
