Transactional memory has been proposed as a general and flexible way to allow programs to read and modify disparate primary-memory locations atomically as a single operation, much as a database transaction can atomically modify many records on disk. Hardware transactional memory supports atomicity through architectural means, whereas software transactional memory supports atomicity through lang...

Transactional memory (TM) promises to unlock parallelism in software in a safer and easier way than lock-based approaches but the path to deployment is unclear for several reasons. First of all, since TM has not been deployed in any machine yet, experience of using it is limited. While software transactional memory implementations exist, they are too slow to provide useful experience. Existing ...

Women who engage in transactional sex are more likely to experience intimate partner violence (IPV) and are at higher risk of HIV. However, women engage in transactional sex for a variety of reasons and the precise mechanism linking transactional sex and IPV is not fully understood. We conducted a behavioural survey with a cross-sectional sample of 401 women attending 1 rural and 1 urban public...

Transactional Memory is a promising parallel computing paradigm, increasingly used nowadays, that allows easy parallelization of sequential programs and can expose a great level of parallelism. Many different approaches exist. One such approach is parallel-nested Transactional Memory, where transactions are allowed to spawn their own child transactions, effectively exposing additional levels of...

This workshop paper explores some ideas for value prediction and data speculation in hardware transactional memory. We present these ideas in the context of false sharing, at the cache line level, within hardware transactions. We distinguish between coherence conflicts, which may result from false sharing, from true data conflicts, which we call transactional conflicts. We build on some of the ...

Web transactions (e.g. buying a CD player on the Web) typically involve a number of steps spanning several pages. This task gets strenuous when the Web is accessed non-visually (e.g. when the user is a visually handicapped individual). But usually one needs to browse only a small fragment of a Web page in a transactional step such as a form fill-out, selecting an item from search results, etc. ...
