In this series of lectures, I introduce \u201cTransactional Memory\u201d (TM) as a technique for building shared memory data structures. As I illustrate, it can be much easier to build shared memory data structures using TM than it is to use conventional abstractions such as locks, or the atomic compare-and-swap instruction. In this lecture, I look at the semantics of programming language constructs built over TM\u2014for example, how programs using TM interact with the existing concurrency-control features of a language\u2014and some initial ideas for what it means for a program to use TM correctly.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Writing concurrent programs is notoriously difficult, and is of increasing practical importance.
